Terms
Plain language. Last updated August 2026.
By using Limber you agree to these terms. They are short because the app is: there is no account, no server holding your data, and nothing here that needs three pages to say.
What Limber is
Limber is a mobility app. You measure your own range with a small battery of self-tests, it computes a score and a datum from those readings, and it builds short sessions from them. It is not a medical device, it does not diagnose, and it does not treat anything. Nothing in the app or on this site is medical advice.
If you have sharp pain, numbness or tingling, a recent injury, or you are recovering from surgery, see a qualified professional before using it. Stop if a movement hurts. A stretch should read four to six out of ten, never sharp.
No account, and your content
There is nothing to sign up for. The readings, sessions and notes you enter are yours, they are stored on your own device, and we neither hold a copy nor claim any licence over them. Keeping them is your responsibility: if you delete the app or lose the phone, they are gone, because there is no cloud backup to restore from.
Fair use
Do not try to break, overload or reverse-engineer the app, and do not redistribute its content. You must be old enough to enter into a contract where you live.
Free core, and Limber Pro
The measuring is free and stays free: the full test battery, your Range Score and every reading behind it, re-tests as often as you like, one session a day of up to ten minutes, your streak, your whole record, and writing sessions to Health. None of that is a trial and none of it expires.
Limber Pro is an optional subscription that adds longer sessions, the full routine library, every day of every track, and the deeper hold grammar. It is billed through the App Store or Google Play, renews until you cancel, and is cancelled there rather than with us. The price is shown before you buy, and the price the store shows is the price you pay. If a subscription lapses your history stays; the paid features simply switch off.
The score
Your Range Score and your datum are computed from readings you take, with a wall and a tape, by a fixed protocol. That makes them repeatable and comparable with your own earlier readings. It does not make them a clinical assessment, and they are not a diagnosis, a fitness certification, or a prediction about injury.
Availability
We work to keep Limber running but do not promise it will always be available or error-free, and we may change or discontinue features. Limber is provided "as is", without warranties, to the extent the law allows.
Ending it
Stop using Limber whenever you like. Deleting the app removes everything it holds — see deleting your data. There is no account for us to suspend or close.
App Store
If you got Limber from the Apple App Store, a few things are worth stating plainly:
- This agreement is between you and Must Have Apps SIA, not with Apple. We — not Apple — are responsible for Limber and its content.
- Apple has no obligation to provide any maintenance or support for Limber. If something is wrong, write to us.
- Limber comes with no warranty beyond what the law requires. If it ever fails to conform to an applicable warranty, you may tell Apple and Apple will refund the purchase price, if any; beyond that refund Apple has no warranty obligation whatsoever, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform are ours to answer for, not Apple's.
- We, not Apple, are responsible for handling any claim that Limber or your use of it infringes someone's intellectual property, and for any product-liability claim, any claim that Limber fails to meet a legal or regulatory requirement, and any claim under consumer-protection or similar law.
- You confirm you are not in a country subject to a US Government embargo or designated as terrorist-supporting, and that you are not on any US Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms, and on your acceptance of them Apple has the right to enforce them against you as a third-party beneficiary.
Changes
We may update these terms; when we do, we will change the date above. Continuing to use Limber means you accept the update.

TODO(launch) This page still needs the publisher's registered company number and address, and the governing law and venue for any dispute. Must Have Apps SIA is named because it is the publisher; the rest has deliberately not been guessed at, and a lawyer should read the finished page before it is linked from a store listing.
