GainsAI

Personal training platform

Plan a training block, log the sets you actually complete, and read where your training is going.

Programs, workout logging, progress analysis, check-ins, meal planning and backup in one Android app. The point is to connect what you planned with what you did, so the next suggestion has something to stand on.

Features

From a training plan to the next useful decision

The app reads the training you logged and puts recommendations next to it, instead of only drawing charts.

  1. AI-assisted training plans

    Build a first plan around your profile and training preferences. Keep programs in a library and go back to the one that fits the current block.

  2. Log the work you did

    Record exercises, sets, reps and loads during the session. Workout history turns completed sessions into a record you can actually use later.

  3. Progress with context

    Exercise signals, estimated 1RM trends, body metrics and weekly check-ins read together. The app can point at consistency, recovery or training priorities that need attention.

  4. Plans beyond the workout

    Multi-day meal plans, weekly check-ins and body metrics sit alongside the training data when those tools fit your routine.

How it works

Plan, train, review, keep

  1. Set the direction

    Your training profile and preferences start a program that gives the sessions a structure.

  2. Train and log

    Do the session and capture what happened, from the working sets to the exercises you swapped.

  3. Review and adjust

    Progress analysis, check-ins and Coach guidance help you pick a sensible next focus.

  4. Keep the data

    With Pro, connect Google Drive for backup and restore under a Google account you authorise separately.

Coach

What the recommendations are, and what they are not

GainsAI Coach

Coach uses the app's own backend, your current training context and deterministic coaching logic to explain program, progress and training-priority signals.

It is built to help you understand possible next actions. It does not diagnose, treat or replace a doctor, physiotherapist, dietitian, personal trainer or other healthcare professional.

Adaptive, not absolute

Recommendations can draw attention to exercise progress, training consistency, recovery check-ins and body-trend context. They are suggestions to assess, not promises of a result.

Training decisions stay yours. Use your own judgement and seek qualified professional advice when your circumstances call for it.

Prices and availability are shown in Google Play before purchase and can vary by country or region.

Subscriptions are managed through Google Play. You can restore purchases in the app; an active Google Play subscription can also be managed in Google Play. Pro access is shown in the app as a securely checked entitlement.

Privacy

Account, data and backup

Privacy and account controls

GainsAI uses authenticated backend services for account-linked features. Google sign-in, Firebase Authentication, the backend and Google Drive are used only for the functions you choose to use.

You can delete a GainsAI account from the app. The flow covers backend and local account data, can include the GainsAI Drive backup, and attempts Firebase Authentication cleanup where possible. Deleting an account does not cancel a Google Play subscription.

Google Drive backup and restore

Pro includes Google Drive backup and restore. Drive is authorised separately, and backups are stored in Google Drive's app-specific storage area.

Before replacing an existing backup, the app can ask you to review recovery and account-mismatch information, so changing device or account is a decision you make with the facts in front of you.

FAQ

Questions people ask first

Does GainsAI replace a healthcare or fitness professional?

No. GainsAI is a fitness and wellness tool. It does not provide medical diagnosis, treatment, emergency assistance or professional healthcare advice.

How is Pro access handled?

Purchases are made through Google Play. The app sends the purchase for secure backend verification, then shows the backend-confirmed Pro entitlement. You can restore purchases and manage a Google Play subscription through the app or Google Play.

Can I back up or restore my data?

Yes. GainsAI Pro includes Google Drive backup and restore after you authorise a Google account for Drive. The Drive connection is separate from your GainsAI sign-in.

How can I delete my account and data?

Use the in-app account deletion flow or the published deletion instructions. The app can delete account data and optionally remove the GainsAI backup from Google Drive; a subscription must be managed separately in Google Play.
