TorqueWise Terms of Use

Last updated: November 15, 2026

These Terms of Use (“Terms”) are an agreement between you and Omnis Dragon LLC, doing business as Journey On (“Journey On”, “we”, “us”). They cover the TorqueWise app for iPhone and iPad (“the app”) and the TorqueWise web app at torquewise.journeyon.co (“the web app”; together with the app, “TorqueWise”). Please read them in full, and especially section 4 (Using the results), section 11 (No warranty) and section 12 (Limitation of liability). By downloading or using TorqueWise, you agree to these Terms. If you do not agree, do not use TorqueWise.

1. Who we are

TorqueWise is made by Omnis Dragon LLC, a Tennessee limited liability company doing business as Journey On, 116 Agnes Rd, Ste 200, Knoxville, Tennessee 37919-6306, United States. Email: support@journeyon.co.

2. Apple’s license agreement, the web app, and these Terms

You get the app from Apple’s App Store. Your license to use the app comes from Apple’s Licensed Application End User License Agreement (the “Standard EULA”, https://www.apple.com/legal/internet-services/itunes/dev/stdeula/), with Journey On as the licensor. These Terms add terms that are specific to TorqueWise. They do not replace the Standard EULA, and you should read the two together. If they conflict, the Standard EULA governs your license to the app, and these Terms govern everything else. Apple’s Media Services Terms and Conditions govern your Apple Account and any payment to Apple.

The web app does not come from the App Store, and the Standard EULA does not cover it. We give you a personal, non-exclusive, non-transferable right to use the web app under these Terms, for your own work and for the work of the organization you work for.

3. Who may use TorqueWise

• You may use TorqueWise if you can form a binding contract where you live. If you are under the age of majority where you live, use TorqueWise only with the permission of a parent or guardian. That parent or guardian agrees to these Terms for you and is responsible for your use.
• You may not use TorqueWise if you are in a country that is subject to a U.S. Government embargo or that the U.S. Government has designated as a “terrorist supporting” country. You may not use it if you are on any U.S. Government list of prohibited or restricted parties.
• If you use TorqueWise for an organization, such as your employer, you agree to these Terms for that organization as well.

4. Using the results

4.1 What TorqueWise is for. TorqueWise works out a tightening torque and the preload it gives for a bolted joint, from the bolt, the joint, the preload target, and the tool you choose. It also checks bearing pressure, thread engagement, bolt length, corrosion, and lock nuts, and gives a tightening sequence. It is a calculator for mechanics, technicians, and engineers, who decide whether and how to use its results.

4.2 The manufacturer’s specification comes first. Where the maker of the equipment, vehicle, machine, structure, or fastener specifies a torque, a preload, a tightening procedure, or that a bolt must be replaced and not used again, follow that specification and not TorqueWise.

4.3 Joints whose failure could cause harm. TorqueWise does not replace the design, verification, and procedures required for joints whose failure could cause injury, death, or serious damage. These include joints in:

• aircraft and spacecraft;
• the wheels, brakes, steering, suspension, and seat belts of vehicles;
• cranes, hoists, and lifting and rigging equipment;
• pressure vessels, boilers, piping, and flanged joints with gaskets;
• buildings, bridges, towers, and other structures;
• medical devices, and machines that people ride in or work inside.

For these joints, a qualified engineer specifies the joint and its tightening, and the code or standard that applies is followed, including its installation, inspection, and test requirements (for example, the RCSC Specification and EN 1090-2 for structural bolting, and ASME PCC-1 for flanged joints). Results from TorqueWise may help with that work, but they are not a substitute for it.

4.4 Torque does not guarantee preload. The same torque gives a different preload when friction changes. TorqueWise uses the friction of the finish and thread condition you choose, or the friction value you enter. Real friction varies with the batch of parts, their surfaces, the lubricant and how it is applied, the tool, and the speed of tightening. The preload range TorqueWise shows is an estimate from the tool’s tightening factor (α_A in VDI 2230), not a measured or guaranteed range. Where preload matters, measure the friction of your parts (ISO 16047) and enter it, or measure the preload directly.

4.5 You are responsible for how you use the results. You decide whether and how to use anything TorqueWise shows, and you bear the risk of that decision. Check that the inputs match your parts and your joint before you use a result. If you give results to others, do not present them as an engineer’s approved or certified values.

4.6 No warranty, limited liability. TorqueWise and its results are provided “as is”, without warranty of any kind, including any warranty of accuracy (section 11). To the maximum extent permitted by law, Journey On is not liable for any loss, damage, injury, or claim that results from using or relying on TorqueWise or its results (section 12). For the app, these sections add to the “No Warranty” and “Limitation of Liability” sections of Apple’s Standard EULA and are consistent with them.

5. Accuracy and limits of the calculation

5.1 Results are estimates from published methods. TorqueWise calculates with the method of VDI 2230 Part 1 (2015) and the values of the standards and references listed in the app under Sources and method, for example ISO 898-1, SAE J429, the RCSC Specification, EN 1090-2, and ASME PCC-1. Where a value is an estimate rather than a value from a standard, TorqueWise says so.

5.2 What the calculation leaves out or simplifies.

• Temperature. Values assume room temperature. Thermal expansion, relaxation, and creep are not calculated.
• Materials. Steel and stainless steel bolts, and the clamped materials listed in TorqueWise. Other materials are entered by their limiting bearing pressure and engagement factor.
• Friction. One friction value is used for the thread and under the head or nut.
• Loads. External loads on the joint, joint stiffness, fatigue, and embedding (the settling of surfaces after tightening) are not calculated. For short grips, TorqueWise shows a note about embedding only.
• Geometry. Heads, nuts, washers, and holes are taken to be of standard sizes. The bearing diameters under the heads of inch bolts are estimated from the head width; TorqueWise says so.
• Structural bolting. The Structural target gives a starting value. The RCSC Specification and EN 1090-2 require the installation method and the verification they specify.

Sources and method in TorqueWise describes the method in more detail.

5.3 Checked against published values. Each time you open Sources and method, TorqueWise runs 27 checks against published values (VDI 2230 Table A1, Fastenal clamp-load tables, RCSC Table 5.2, EN 1090-2 preload values, ISO 2320, and others) and shows each result. These checks show that the calculation reproduces those published values. They do not show that a real joint reaches the preload shown.

6. Your saved joints

• They stay on your device. Your inputs and saved joints are stored on your device or in your browser. We do not receive them. The Privacy Policy describes what TorqueWise stores.
• Keeping copies is your responsibility. Deleting the app, or clearing this website’s data in your browser, deletes the saved joints stored there. TorqueWise does not sync them between devices. Keep a record of any value that matters to your work.
• Feedback. If you send us ideas or suggestions, we may use them without any obligation to you.

7. Acceptable use

You agree not to:

• use TorqueWise in breach of any law, or of the rights of others;
• copy, modify, reverse-engineer, decompile, or try to extract the source code of the app, except as the Standard EULA, the license of an open-source component, or the law allows;
• copy, publish, or host TorqueWise or its pages elsewhere, or offer it as a service to others;
• resell, rent, or redistribute the app;
• interfere with this website or with other people’s use of it;
• present results from TorqueWise as an engineer’s approved or certified values, or use them in place of the work described in section 4.3.

8. No purchases inside TorqueWise

TorqueWise has no account, no subscription, and no purchases inside the app or the web app. If the App Store shows a price for the app, Apple takes the payment and handles refunds under its own terms; we never see your payment details. Nothing in these Terms limits any right to a refund that the law gives you.

9. Services and terms of others

• Apple. Apple runs the App Store and your Apple Account, under Apple’s own terms and privacy policy.
• GitHub. GitHub, Inc. hosts this website, the web app among it. The Privacy Policy says what GitHub receives.
• Your network provider. You must follow the terms of your mobile or internet service, and you are responsible for any data charges when you load the web app.
• Links. Sources and method in TorqueWise links to the websites of the standards’ publishers and other sources, and this website links to our Instagram page. In the app, links open in your browser. We are not responsible for websites or services we do not run.

10. Our rights and third-party software

TorqueWise, its calculations, texts, drawings, 3D views, and design belong to Omnis Dragon LLC or its licensors. They are protected by copyright and other laws, and all rights not granted to you are reserved. TorqueWise includes open-source software and fonts under their own licenses, listed in TorqueWise under Third-party notices, at the bottom of the page. For those components, their licenses apply. “TorqueWise” and “Journey On” are names of Omnis Dragon LLC. The standards and references named in TorqueWise belong to their publishers and authors; naming them does not mean that they endorse TorqueWise. Grade and product names, such as “8.8”, “A325”, and “B7”, name grades, not suppliers.

iPhone and iPad are trademarks of Apple Inc., registered in the U.S. and other countries and regions.

11. No warranty

You use TorqueWise and its results at your sole risk. To the maximum extent permitted by applicable law, TorqueWise, its results, its reference values, and any services provided through it are provided “as is” and “as available”, with all faults and without warranty of any kind. Journey On disclaims all warranties and conditions, whether express, implied, or statutory, including any warranty or condition of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, quiet enjoyment, and non-infringement. In particular, we do not warrant that a joint tightened to a torque TorqueWise shows reaches the preload shown, that it will not loosen, slip, leak, or break, that the reference values match any real part or material, or that TorqueWise will be uninterrupted or free of errors. No advice or information from us creates a warranty. Some jurisdictions do not allow the exclusion of implied warranties or limits on statutory rights of consumers, so some of these exclusions may not apply to you.

12. Limitation of liability

To the maximum extent permitted by applicable law, Omnis Dragon LLC, its members, managers, employees, and contractors are not liable for:

• personal injury or damage to property;
• incidental, special, indirect, consequential, exemplary, or punitive damages;
• loss of profits, revenue, data, or goodwill, or business interruption.

This applies to any of these arising out of or related to your use of, inability to use, or reliance on TorqueWise or its results, however caused and under any theory of liability, even if we were told they were possible. Our total liability to you for all claims is limited to fifty U.S. dollars (US$50), as in the Standard EULA, except where the law requires otherwise. These limits apply even if a remedy fails of its essential purpose. Some jurisdictions do not allow these limits, so some of them may not apply to you. Nothing in these Terms limits liability that cannot be limited by law, such as liability for fraud, or where the law does not allow it, for death or personal injury caused by negligence.

13. Indemnity

To the extent the law allows, you agree to defend, indemnify, and hold harmless Omnis Dragon LLC and its members, managers, employees, and contractors from any third-party claim, loss, or cost (including reasonable legal fees) that arises from:

• joints you design, assemble, tighten, or approve, or work you do for others, using results from TorqueWise;
• your breach of these Terms;
• your breach of any law or of the rights of others.

14. Apple

For the app, you and Journey On agree to the following:

• Parties. These Terms are between you and Journey On only, not with Apple Inc. (“Apple”). Journey On, not Apple, is solely responsible for the app and its content.
• Maintenance and support. Journey On is solely responsible for any maintenance and support of the app, as described in these Terms or required by law. Apple has no obligation to provide maintenance or support for the app.
• Warranty. Journey On is responsible for any product warranty, express or implied by law, to the extent it is not effectively disclaimed. If the app fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, to you. To the maximum extent permitted by law, Apple has no other warranty obligation for the app. Any other claims, losses, liabilities, damages, costs, or expenses from a failure to conform to a warranty are Journey On’s responsibility.
• Product claims. Journey On, not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession or use of it. These include product liability claims, claims that the app fails to conform to a legal or regulatory requirement, and claims under consumer protection, privacy, or similar laws.
• Intellectual property. If a third party claims that the app, or your possession and use of it, infringes that third party’s intellectual property rights, Journey On, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of that claim.
• Legal compliance. You represent that you are not in a country that is subject to a U.S. Government embargo or that the U.S. Government has designated as “terrorist supporting”, and that you are not on any U.S. Government list of prohibited or restricted parties.
• Third-party terms. You must comply with applicable third-party terms when you use the app, such as your network provider’s terms.
• Third-party beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms. Once you accept these Terms, Apple has the right, and is deemed to have accepted the right, to enforce them against you as a third-party beneficiary.
• Contact. Journey On’s name, address, and contact details for questions, complaints, or claims about the app are in sections 1 and 20.

15. Export and sanctions

You may not use, export, or re-export TorqueWise except as U.S. law and the law of the place where you obtained it allow. You may not use it for purposes U.S. law prohibits, including the development, design, manufacture, or production of nuclear, missile, chemical, or biological weapons.

16. Changes to TorqueWise and to these Terms

We may update TorqueWise and these Terms. When we change these Terms, we post the new version at https://torquewise.journeyon.co/terms/ with a new “Last updated” date. If a change materially affects you, we say so in the app’s update notes or in TorqueWise before it takes effect. If you keep using TorqueWise after a change takes effect, you accept the new Terms. If you do not accept them, stop using TorqueWise.

17. Ending these Terms

You may end these Terms at any time by deleting the app and no longer using the web app. Your rights under these Terms end automatically if you breach them. Sections 4, 5, 6, 10, 11, 12, 13, 14, 18, and 19 continue to apply after these Terms end.

18. Governing law and disputes

These Terms are governed by the laws of the State of Tennessee, United States, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. Before you start a legal claim, email support@journeyon.co and give us 30 days to try to resolve it. Any claim not resolved that way goes to the state courts in Knox County, Tennessee, or the U.S. District Court for the Eastern District of Tennessee, and you and we consent to their jurisdiction. If you are a consumer, you keep any protection that the mandatory law of your country of residence gives you, including the right to bring a claim in your local courts where that law provides it. The governing-law clause of the Standard EULA continues to apply to the license it grants.

19. General

These Terms, the Standard EULA for the app, and the Privacy Policy are the whole agreement between you and us about TorqueWise. If a court finds part of these Terms unenforceable, the rest stays in effect, and that part is enforced as far as the law allows. If we do not enforce a right, we do not give it up. You may not transfer your rights under these Terms. We may transfer ours to a company that takes over TorqueWise. These Terms are written in English, and the English version controls.
