How to make an app for a personal trainer

A personal trainer juggles clients in different places, each with a package of sessions, a workout plan and measurements to check every few weeks. An app keeps each client's sessions left, plan and progress on your phone, so you walk into every session prepared.

Who uses the app

Usually only you, and the data can stay on your phone. If clients should open their own workout plan and progress, or you work with another trainer, connect your own Supabase database and turn on sign-in.

The screens a personal trainer app needs

Today: Today's sessions by time and place: the client's home, the gym or online, with a Google Maps link
Clients: Each client's goal, health notes they shared, package, sessions left and fee status
Workout plans: Each client's plan by day: exercises, sets, reps and weights, changed as they progress
Progress: Weight and body measurements by date, and progress photos the client agreed to
Payments: Packages paid and due, receipts as PDFs and a list of renewals coming up

Features worth asking for

A session package that counts down each time you mark a session done
A WhatsApp reminder when a package has two sessions left
Workout and diet plans as PDFs to share with a client
Measurements over time to show the client in a session
Google Maps links to each home client's address
Client sign-in to see their own plan and progress
Online package payment through your own Razorpay account, if you want it

Where the data lives

If only you use the app, the data can stay on your phone and works offline. For client logins, or to share clients with another trainer, connect your own Supabase database; to take package fees online, connect your Razorpay account too, and the money goes to you.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Today, Clients, Workout plans, Progress, Payments.
Describe it to AppCub. Paste the request below, changed to your own business and details.
Check the plan. AppCub shows the screens and features it will build. Change them in the chat until they are right; seeing the plan is free.
Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
Share it. Share it as a web link, an APK file, or publish it on Google Play from your own developer account.

Copy this request, change the details to match your personal trainer, and paste it into AppCub:

Make an app for my personal training work, Aman Srivastava Fitness in Lucknow. Clients train at home, at the gym or online. Each client has a goal, health notes, a package of 12 or 20 sessions and a fee. Show today's sessions with time, place and a Google Maps link. Mark a session done and count down the package; remind me on WhatsApp when 2 sessions are left. Keep each client's workout plan by day with sets and reps, and weight and measurements by date. Make PDF plans and receipts. Dark blue and lime green.

Tips for a personal trainer app

Start with clients, sessions left and payments; add measurements and plans once that works.
Clients' health details and body photos are personal: store them only with their agreement and use sign-in if clients log in.
Ask for an exercise list you can pick from quickly, so building a plan takes a few taps.
Use a test client for a week before you enter your real clients.
Ask for the client screens in Hindi as well if some clients prefer it.

Good to know

AppCub doesn't connect to fitness bands, smart watches or weighing machines, and it doesn't run video sessions. Measurements are entered by hand, and online sessions stay on your video-call tool.
AppCub builds Android apps. You can also share the app as a web link that opens on any phone; for the iPhone App Store, AppCub’s team can do it for you.

Questions

Can clients see their own workout plan in the app?

Yes, with your own Supabase database connected and sign-in turned on. Each client sees only their plan, sessions left and progress.

Can the app track sessions left in a package?

Yes. Each session you mark as done comes off the package, and the app shows who is close to renewing.

Can I track a client's weight and measurements?

Yes. Ask for a progress screen with weight and measurements by date, and the app shows the change over time.

Can the app sync with a client's smart watch?

No. AppCub doesn't connect to fitness bands or watches; measurements and notes are entered in the app.

Can I share a diet plan from the app?

Yes. Make the plan in the app and share it as a PDF on WhatsApp, or let the client open it after sign-in.

Can I take payments for training packages in the app?

Yes, with a pay button using your own Razorpay account; connect Razorpay and Supabase from the chat first.
