What Gainsmith does

Five parts that work together: what you lift, eat and weigh ends up in one place.

  1. Training

    Every set has a plan.

    Build plans with days, sets, rep ranges and target RIR. During a workout, last time’s numbers are already filled in, along with the next weight and the reason for it.

    • Progression that explains itself
    • Records for every exercise
    • Rest timer with notifications

  2. Nutrition

    Log food without the typing.

    Scan a barcode, search the food database or snap your plate. The AI estimates the meal, you check it and save.

    • Barcode scanner
    • AI meals from a photo or text
    • Macros against your daily goal

  3. Progress

    See what’s changing.

    Weight, measurements and body fat over 30 days, 90 days or a year. Put progress photos side by side; for now they stay on your device.

    • Body stats and measurements
    • Progress photos side by side
    • Weekly review

  4. Coach and phase

    Suggestions, not pep talk.

    Once a week the coach looks at your training, food and weight. It only speaks up with a concrete suggestion and a reason. Nothing changes without your okay.

    • Bulk, maintain or cut
    • Calorie goal from your weight trend
    • Ideas when an exercise stalls

  5. Health

    All your numbers in one place.

    Connect Apple Health or Health Connect. Sleep, steps, weight, resting heart rate and HRV come in on their own; your workouts and nutrition go back.

    • Apple Health and Health Connect
    • Sleep, steps and weight
    • Choose reading and writing separately

When is the app coming to the App Store and Google Play?

There is no date yet. Until then, Gainsmith runs in your browser. Join the waitlist and we’ll email you at launch.

Where is my data stored?

On your device first. With an account, the app also syncs it with the Gainsmith server, so your phone and browser show the same. Progress photos are not synced for now and stay on the device. For the AI features, the app sends only what needs to be analysed to Claude by Anthropic. The details are in the privacy policy.

Do I need an account?

No. You start without an account, and everything stays on your device. You need an account to sync between your devices and for the AI features.

Does the app work offline?

Yes. On your phone, Gainsmith works with no connection at all. In the browser you need a connection to open it; after that you can keep logging offline. Only sync, the online food search and the AI need a connection.

Which devices and languages are supported?

Gainsmith is built for iPhone and Android and already runs in any current browser. Apple Health works on iPhone, Health Connect on Android. The app speaks German and English.
