Isoletics
Terms of service
Last updated 25 October 2026.
These are the terms you agree to by using Isoletics. The short version: the app measures what you can do and tells you what to train next, it is not a physiotherapist, the tests and your ladder are free, and the training plan is a subscription you buy from Apple and can stop at any time.
Who you are agreeing with
Isoletics is operated by Gilvara Ltd, a private limited company registered in Scotland, company number SC854313, registered office 5 5/4 Nova Scotia Place, Edinburgh, Scotland, EH12 9FU. In these terms, "we" and "us" mean Gilvara Ltd, and "you" means the person using the app.
Contact: support@isoletics.app. For anything about your data, privacy@isoletics.app and the privacy policy.
Training is physical, and this is the part to read
Isoletics is a training tool, not medical advice. We are not doctors, physiotherapists or your coach, and the app cannot see you. It takes numbers you type in and returns a progression based on them. It cannot tell whether your form is safe, whether an ache is ordinary or an injury, or whether a movement is wrong for your particular body.
Calisthenics skills load joints heavily — the planche and the front lever put a large share of your bodyweight through the wrists, elbows and shoulders, and the weighted tracks go up to 1.5 times your total bodyweight. You train at your own risk.
- Stop at pain. Not discomfort you have decided to push through — pain. The app says this in the wrist check and it means it everywhere else too.
- Get medical advice before you start if you are pregnant, recovering from or being treated for an injury, or have any condition affecting your joints, heart or blood pressure.
- See someone qualified if something hurts during or after training, rather than re-testing to see whether the number has moved.
- The app will refuse you once. If the wrist check is not passed it will not give you a plan until a re-test clears. Do not work around that.
Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be limited.
What the app is, and what it does not claim
Isoletics assesses your current ability on a skill, places you on a progression ladder, and prescribes the next step. We want you to know exactly how solid that is:
- The order of the progressions follows established calisthenics coaching, and the level-and-track model is adapted from the published progression charts in Steven Low's Overcoming Gravity 2.
- The specific difficulty level and the pass and mastery thresholds on every exercise were set by us. They are our best judgement, they have not been validated against user outcomes, and some of them will be wrong. We correct them as we learn.
- We do not promise you will reach any particular skill, in any particular time, or at all. Whether you do depends on your training, your consistency, your body and your history, none of which the app controls.
Free and paid
| Part of the app | Cost |
|---|---|
| The tests, your placement and your ladder | Free, with no account and no card |
| The training plan and the session logger | Subscription |
If we change what sits on which side of that line, we will tell you in the app before it takes effect, and anything you have already paid for stays available for the period you paid for.
The subscription
Trial
New subscribers get a 14-day free trial. If you do not cancel before it ends, it becomes a paid subscription at the price shown to you when you started it.
Price and renewal
The price is shown in the app before you buy and is charged in pounds sterling. Subscriptions renew automatically — monthly or annually, matching the plan you chose — until you cancel.
Your price does not go up. If we raise prices for new subscribers, you keep the price you signed up at for as long as your subscription runs without a break. If you cancel and come back later, you join at whatever the price is then. This is a commitment we make in the app and we are repeating it here so it is part of the agreement.
Apple takes the payment, not us
Purchases are made through the App Store. Apple is the seller of record, which means:
- You cancel in the App Store — Settings → your name → Subscriptions on your device — not in Isoletics. We cannot cancel it for you.
- Cancelling stops the next renewal. You keep access until the end of the period you have already paid for.
- Refunds are requested from Apple, at reportaproblem.apple.com, and are Apple's decision. We do not hold your payment and cannot issue a refund ourselves. If you think something went wrong, tell us anyway — we will help you put the request together.
- Your payment details never reach us. We are told whether a subscription is active, and nothing else about the card.
Your right to cancel
Because this is digital content supplied immediately, the 14-day right to change your mind under the Consumer Contracts Regulations 2013 does not survive once supply begins — which is what starting the trial does. That is a statutory position, not a term we are imposing, and it does not affect your rights if the app is faulty or not as described. Those rights are set out below.
If the app is faulty
Under the Consumer Rights Act 2015 digital content must be of satisfactory quality, fit for purpose and as described. If Isoletics is not, you are entitled to have it repaired or replaced and, where that is not possible or not done in a reasonable time, to a price reduction. These rights sit alongside anything in these terms and nothing here takes them away.
Tell us first, through You → Report something in the app or at support@isoletics.app. A report from inside the app arrives with the screen, the app version and your device attached, which is usually the difference between a fix this week and a fix eventually.
Your account
You can use the app with no account at all; everything is stored on your device. An account exists only so your numbers survive a new phone, and it is an email address and nothing else — no password, because signing in is a link we email you.
- You must be 16 or over to use Isoletics.
- Keep access to your email secure. Anyone who can read your inbox can sign in as you.
- Do not share one account between several people. The plan is built from one person's test results and mixing two people's numbers produces a plan that fits neither.
What you may not do
- Copy, scrape or republish the ladders, thresholds, cues, photographs or videos. They are the product, and they took a long time to make.
- Reverse engineer the app, or try to unlock paid features without paying for them.
- Resell, sublicense or redistribute any part of Isoletics, or present its progressions as your own coaching product.
- Use the app to harm anyone, or to build a competing product from its data.
You may, of course, use what you learn in your own training, tell people what level you reached, and share the cards the app makes for exactly that purpose.
Who owns what
The app, its design, the written cues, the imagery and the progression data belong to Gilvara Ltd or are licensed to us. You get a personal, non-transferable right to use them while your subscription or free use continues — not ownership of them.
Your training numbers are yours. We use them to produce your plan and, in aggregate and anonymised form, to improve the levels and thresholds for everyone. The privacy policy is the detail, and it is the binding statement on data.
Sharing cards
The app can produce an image of a result for you to post. It carries no name and no personal detail, only the skill, the step and a photograph of the position. What you do with it is yours; what it says about you is only what you chose to share.
Limits on our liability
Read this with the injury section at the top, which is the part that matters most and which we do not limit.
Subject to that, and to anything else that cannot lawfully be limited: we are not liable for loss that was not reasonably foreseeable when you started using the app, for lost training progress, or for loss arising from a progression being rated at the wrong difficulty. Where we are liable, our total liability to you is limited to the amount you paid us in the twelve months before the claim — and if you have never paid us, to £100.
We do not promise the app will be available without interruption. It depends on Apple's services, on our hosting provider and on your device, and any of them can fail.
Ending it
You can stop using Isoletics at any time, delete the app, and delete your data from inside it — You → Start over wipes your tests and plans on the device, and the privacy policy explains how to delete an account entirely.
We may suspend or end your access if you break these terms in a way that is serious or repeated. If we do, and you have paid for a period you have not used, we will arrange a refund of that part through Apple.
Changes to these terms
If these terms change in a way that affects you, the app will tell you before the change takes effect. The date at the top always reflects the current version. Continuing to use the app after a change means you accept it; if you do not, stop using it and cancel.
Law and where disputes go
These terms are governed by the law of Scotland, and the Scottish courts have jurisdiction. If you live elsewhere in the United Kingdom you keep the right to bring proceedings in your own country's courts, and you keep the benefit of any consumer protection that applies where you live.
Complaints
Write to support@isoletics.app and we will reply. If a complaint is about your personal data and you are not satisfied with our answer, you can complain to the Information Commissioner's Office at ico.org.uk.
