Terms of Use
The things Apple’s standard licence does not say, and this app needs said.
Last updated
These terms apply to the Metrics Nest iPhone app, published by Ricardo Cerqueira. Installing or using the app means you accept them. Apple’s Licensed Application End User License Agreement also applies; where the two disagree, these terms govern the app itself and Apple’s terms govern your purchase and download of it.
Not medical advice
Metrics Nest is a personal tracking and motivation tool. It is not a medical device, it does not diagnose, treat, cure or prevent any condition, and nothing in it — including the Balance score, the detail pages and any notification it sends — is medical advice. The Balance score is a judgement the app makes from broadly published general guidance, and it explains on screen exactly how it reached it; it is a prompt to think, not a verdict on your health.
Talk to a qualified healthcare professional about anything that concerns you, and about any change to your exercise, diet or sleep. If you think you are having a medical emergency, contact your local emergency services.
Your data is on your device
The app keeps what it holds on your phone rather than on a server. That is deliberate, and it has a consequence worth stating plainly: if you delete the app, lose the device, or restore it without a backup that includes app data, what the app had recorded is gone. We cannot recover it, because we never had a copy. Your Health app data is unaffected — it was never ours.
Accuracy
Readings come from your own sources — the Health app, connected services, and Bluetooth heart rate monitors. The app presents and combines what those sources report, and cannot be more accurate than they are. Where it cannot say something honestly, it says so rather than estimating.
Paying for the app
The app is free to use. The dashboard draws your last seven days, recording a workout is free, and the badges, the 3 weekly challenges and the leaderboards cost nothing at any tier. Nothing inside the app is sold separately and there is no advertising.
Unlimited lifts the dashboard’s seven-day window to your whole history and reads a heart rate monitor live during a workout, with the Exercises and Analytics views over everything you have logged. It is sold three ways, and each one unlocks exactly the same two things:
- A monthly subscription at £4.99 per month. It renews automatically at the end of each period until you cancel.
- A yearly subscription at £39.99 per year, which is a third less than twelve months of the monthly one. It renews automatically at the end of each period until you cancel.
- Lifetime access at £79.99, paid once. It does not renew, and it lasts as long as the app does. It covers the app on your phone: everything Unlimited unlocks today and every feature added to the app afterwards. It does not cover anything that runs on a server, such as an API, a connection to another service, or an add-on sold separately, whether offered now or later. Lifetime holders can add any such add-on as a subscription of its own; it is the only thing they would ever pay for again.
The two subscriptions are the same app at two billing periods, and you can move between them whenever you like in Settings → your name → Subscriptions. Apple handles the change and credits whatever you have already paid for against the new period.
Prices are the UK App Store’s. Apple sets the equivalent price in every other storefront, and the price you are shown before you confirm is the price that is charged.
The free month
The free month belongs to the subscriptions; lifetime access is a one-time purchase and cannot carry a trial. It is offered once per Apple Account across both subscriptions rather than once on each — taking the free month on the monthly plan and then moving to the yearly one does not begin a second one. Unless you cancel at least 24 hours before it ends, the subscription you started begins and Apple charges the Apple Account it is attached to. Cancelling during the free month costs nothing, and you keep the app until the month runs out.
Cancelling, and what happens after
A subscription is cancelled in Settings → your name → Subscriptions on your iPhone, which is the only place it can be — Apple holds it, not us. Deleting the app does not cancel it. When a subscription ends you do not lose the app — it returns to the free tier: the dashboard goes back to seven days and the monitor is no longer read. The readings on your device are untouched. Nothing is deleted at any point, on any tier: the seven days are a window over what is drawn, not a limit on what is kept, so everything you logged is drawn again the day you subscribe again. Your Health app data was never ours to affect either way.
Refunds
Apple is the seller for everything bought through the App Store, so refunds are Apple’s to give — request one at reportaproblem.apple.com. We have no access to the transaction and cannot issue a refund ourselves. If you are a consumer, your statutory rights are unaffected by anything in this section.
Price changes
The subscription price may change. Apple will tell you before a change affects you and, for an increase, will ask you to agree to it — if you do not, the subscription ends rather than renewing at the new price. Lifetime access, once bought, is never charged again, whatever the price of the app becomes afterwards.
If the app stops
“Lifetime” means the lifetime of the app, which is the only thing it can honestly mean from a one-person publisher. If Metrics Nest is ever withdrawn, the copy on your phone keeps working for as long as your device and iOS let it — it needs no server to run, because it has never had one. That is also why lifetime stops at the app: a server costs money every month for as long as it runs, and a one-time payment cannot honestly promise one, so anything we ever offer that runs on a server is a subscription of its own.
Fair use
Do not attempt to submit falsified scores to the challenge leaderboards, interfere with other players, or use the app to harass anyone. Game Center behaviour is also subject to Apple’s terms, and Apple may act on its own leaderboards independently of us.
Third-party services
Game Center is provided by Apple, as is the App Store that takes your payment. Open Food Facts answers the barcode and food-name lookups. Neither is under our control, and each is governed by its own terms and privacy policy.
Warranty and liability
The app is provided “as is”, without warranties of any kind to the extent the law allows. To the extent permitted by law, Ricardo Cerqueira is not liable for any indirect or consequential loss arising from your use of the app, or for lost data. Nothing here limits liability that cannot be limited by law, and if you are a consumer, your statutory rights are unaffected.
Changes
These terms may change as the app does. The date at the top says when they last did, and continuing to use the app after a change means accepting it.
