Vitals Terms of Service

Last updated 30 August 2026

Vitals is a personal fitness tracker, provided as-is. By using it you agree to the terms below. Read the Privacy Policy too, which covers what data goes where.

Subscription

Vitals is a subscription. Everything in the app is included: tracking, targets, workouts, the exercise library, your supplement stack, and the AI features.

• Price. $4.99 per month, or $39.99 per year. Prices are in US dollars and may differ in your local storefront.
• Renewal. The subscription renews automatically at the end of each period unless you turn off auto-renew at least 24 hours before it ends. Your Apple Account is charged when it renews.
• Managing it. Cancel or change your subscription in the App Store, under your Apple Account, not in Vitals. Cancelling stops the next renewal; it does not end the period you have already paid for.
• Changing plan. You can move between monthly and yearly at any time from Settings, which opens the App Store's own subscription screen. Moving to a longer or more expensive plan starts straight away and the App Store credits the unused part of what you already paid. Moving to a cheaper one takes effect when your current period ends, and until then you keep exactly what you paid for.
• Cancelling. You can cancel whenever you like. Pro keeps working until the end of the period you have already paid for, and is not cut off early. Nothing is charged after that.
• No refunds. Payment for a period that has already begun is not refunded, including if you cancel part way through it, switch plans, or stop using the app. What you get instead is the rest of the period you paid for. Apple operates the store and handles all payment, and Apple may at its own discretion grant a refund under its own policies at reportaproblem.apple.com. That is Apple's decision, not ours.
• AI actions. The AI features are limited to 120 actions a month, which resets on the 1st. Everything else in the app is unlimited. The cap exists because those features cost real money per use.

Health disclaimer

Vitals is not medical advice. The nutrition targets, macro estimates, supplement information and training guidance in this app are general, educational information, not a diagnosis, a prescription, or a substitute for a doctor. Talk to a doctor before changing your diet, starting or stopping a supplement, or changing your exercise routine, especially if you have a medical condition, take medication, are pregnant, or are under 18.

Where the app describes a supplement or peptide, it is describing what the compound is and what the research says about it, for your own reading. That description is not a recommendation to take it. Several compounds referenced in the app are research chemicals with no approval for human use anywhere, and nothing in the app should be read as encouragement to source, dose, or use one.

Targets, doses and upper limits

Every number in Vitals is a target, not an instruction, and you use it at your own risk. Calorie, macronutrient, vitamin and mineral targets are calculated from figures you enter and from published reference intakes. They are estimates for a healthy adult. They cannot know your medical history, your medication, or anything a blood test would show.

Where a nutrient has a tolerable upper intake level, the app warns you when a day's intake goes past it. It does not print that limit as a number next to the target, so it is not a substitute for looking up the figure yourself for anything you supplement.

A target is not a safe maximum. Most sit well below the applicable upper limit, but not all: some reference intakes are themselves more than half of the limit, and some limits apply only to supplements and are deliberately not compared against food at all. As a specific example, the app may raise a vitamin C target to 1,000 mg on a day you record being unwell, and to 200 mg on a day of heavy training. The upper limit for an adult is 2,000 mg a day, and it is lower under 19. A raised target is not a claim that the nutrient treats, prevents, cures or shortens any illness, and nothing in this app should be read as one.

If you are pregnant or breastfeeding, under 18, have kidney disease, haemochromatosis or any condition affecting how you absorb or clear nutrients, or take any prescription medicine, the reference intakes this app uses may not apply to you and some of them could be actively wrong for you. Ask a doctor or a registered dietitian rather than an app.

Tracking what is left in a vial

For anything that arrives as a powder and is mixed before use, Vitals can count what is left: how many doses a vial holds at the dose you entered, how many of them are gone, how much is still in the vial, and roughly the date it runs out. It is a stock counter, the same idea as counting the capsules left in a bottle.

It does not work out doses. It will not tell you how much liquid to draw, what dose to use, how often to use it, or what to use at all. It has no view on any of that. If you are looking for a number to put in a syringe, this app does not give you one.

All of it is arithmetic on numbers you typed in. The app cannot know what is actually in your vial, how strong it really is, whether it matches its label, or whether it is sterile. If what you entered is wrong, everything it counts back is wrong, and it will not look wrong.

The amount it reports as remaining assumes you kept to the schedule you entered. It reads that schedule, not what you actually did, so it is an estimate and can be wrong in either direction.

Many compounds sold in this form are not approved for human use, are prescription only where you live, or both. Using them carries real risks. Nothing in this app is encouragement to do so, and the decision and its consequences are yours. Talk to a doctor rather than an app.

The AI features are estimates, not measurements

Describing a meal, photographing a label, and asking about a claim all go through Claude, Anthropic's AI model, as described in the Privacy Policy. AI output can be wrong: a macro estimate can miss, a label can be misread, a research summary can be incomplete or out of date. Treat every number the AI gives you as an estimate to sanity-check against the label, the scale, or your own judgment, not as a lab measurement.

Using the shared AI service

The AI features run through a server Vitals operates, paid for out of Vitals' own budget, not yours. Use it only for what the app's own features ask of it: describing food you ate, reading a label you photographed, or checking a claim you typed. Don't script it, batch it, or use it for anything unrelated to your own fitness tracking.

To keep the service usable for everyone, each device carries a daily request cap, and a request can be declined or delayed when the service is under load. That cap may change without notice. Access to the shared service can be rate limited, throttled, or withdrawn at any time, including for a device that abuses it.

No warranty

Vitals is provided "as is" and "as available," without warranty of any kind, express or implied, including any warranty of accuracy, merchantability, fitness for a particular purpose, or that the app or the AI features will be uninterrupted or error-free.

Limitation of liability

To the fullest extent the law allows, Vitals and its developer are not liable for any indirect, incidental, or consequential damages arising from your use of the app, including any decision about diet, supplements, peptides, or exercise made using information from it. Use your own judgment, and a doctor's, for anything that affects your health.

Governing law

Vitals is available to anyone, anywhere. This clause is only about which courts would hear a dispute: these terms are governed by the laws of the State of Colorado, United States, without regard to conflict of law principles.

Changes

If these terms change, the date at the top will change and the app will be updated to point here.
