Designs by Duhart · Vitals for iPhone and Apple Watch
Short, because the app is simple. Using Vitals means you agree to these terms. Last updated 18 September 2026.
Vitals is an interval training, journaling and nutrition app for iPhone and Apple Watch, published by Designs by Duhart. It is licensed to you, not sold, for personal use on Apple devices you own or control, under Apple’s standard licence terms for apps in the App Store as well as these.
Vitals has no free tier. Access requires an auto-renewing subscription, chosen inside the app:
Checkout and billing are handled by Stripe on this website, not by Apple, and the subscription is linked to the phone that started checkout. Each plan renews automatically at the same price until you cancel. You can cancel at any time from Settings, then Subscription, then Manage Subscription in the app; cancellation takes effect at the end of the period already paid for, and no further charges are made. Prices are shown in US dollars; your bank or card issuer may apply currency conversion. If a price changes, you are told in advance and the new price applies only to renewals after that notice.
If a renewal payment fails, access continues while Stripe retries the charge for a few days, then ends. Update the card in Manage Subscription to restore it.
If something is wrong, contact us within 14 days of a charge and we will put it right or refund it. Nothing in these terms limits any refund right you have under the law of the place you live.
The weekly plan is ad-supported. Ads are shown only after you have been asked for consent, and never during a workout. The monthly plan shows no ads.
Vitals is a training tool, not medical advice. Pace zones, energy estimates, macro targets and meal plans are estimates from published formulas and the numbers you enter; they can be wrong for you. Talk to a healthcare provider before starting or changing a training or nutrition programme, and stop if you feel unwell. You are responsible for training safely.
Your workouts, records, measurements and food log belong to you and stay on your phone. How the small amount of data we do hold is handled is set out in the privacy policy, which is part of these terms.
Do not reverse engineer the app, interfere with the subscription service, or use it in a way that breaks the law. We may suspend access for abuse of the service, with a refund of any unused period unless the abuse was deliberate.
We work to keep the subscription service available, and the app keeps working offline for a week if it cannot reach it. We do not promise the service will be uninterrupted or error-free. To the extent the law allows, our liability to you is limited to the amount you paid for the subscription in the twelve months before the claim. Nothing here excludes liability that cannot be excluded by law.
We may update these terms; the date at the top changes and the app tells you on the next launch. If you do not agree, cancel and the old terms apply until your period ends. You may stop using Vitals at any time by cancelling and deleting the app.
