How to make an app for a gym

A gym's money depends on renewals: who joined when, which plan they took, and whose membership ends this week. An app keeps every member, their plan, payments and check-ins in one place, so the counter knows whom to remind before a membership lapses.

Who uses the app

Usually the owner and the front desk. If the desk and the trainers use it on different phones, or members should see their own plan and diet chart, connect your own Supabase database and turn on sign-in.

The screens a gym app needs

Members: Search by name or phone; each member's plan, start and end date, payments, trainer and photo
Renewals: Memberships ending in the next 7 days and those already expired, with a WhatsApp reminder button
Check-in: Mark members in as they arrive and see today's attendance and members who stopped coming
Plans: Your membership plans with duration and fee, and add-ons like personal training
Payments: Fees collected by day and month, pending balances and receipts as PDFs
Trainers: Each trainer's members, and the workout or diet chart given to each member

Features worth asking for

A renewal list with a WhatsApp reminder filled in with the member's name and end date
A list of members who haven't checked in for two weeks, to call before they quit
Freeze a membership for a set number of days when a member travels
Workout and diet charts as PDFs to share with a member
Receipts as PDFs for every payment
Member sign-in to see their own plan, end date and charts
Online renewal payment through your own Razorpay account, if you want it

Where the data lives

If only the front-desk phone uses it, the data can stay on that phone. For trainers on their own phones or member logins, connect your own Supabase database; to let members renew online, connect your Razorpay account as well, and the money goes to the gym.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Members, Renewals, Check-in, Plans, 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 gym, and paste it into AppCub:

Make an app for my gym, Iron Fit Gym in Kharadi, Pune. Plans: 1, 3, 6 and 12 months, plus personal training. Each member has a plan, start date, end date, payments and a trainer. Show memberships ending in the next 7 days with a WhatsApp reminder, and members who haven't come for 14 days. Add check-in for attendance, a freeze option for travel, PDF receipts, and workout and diet charts trainers can give to members. Show daily and monthly collection. Black and orange colours.

AppCub has a ready-made app you can start from: see it here.

Tips for a gym app

You can start from the ready-made gym app and change it in the chat.
Enter your current members' end dates first; the renewals list is often the screen that pays for the app.
Decide your freeze and refund rules before asking AppCub, so the app follows them exactly.
Take members' photos only with their consent, and keep health notes short.
Run the app beside your register for one week before you stop the register.

What it costs

Describing your app and seeing AppCub’s plan for it is free.

Google Play needs a paid plan (it includes the Play Store bundle and your app’s signing key) and your own Google Play developer account, a one-time US$25 fee to Google.
Work that fails or is rolled back costs no credits.

Good to know

AppCub doesn't connect to biometric or RFID door machines, treadmills or fitness bands, and it doesn't send automatic SMS. Check-ins are marked in the app, and reminders go out when the desk taps the WhatsApp button.
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

Is there a ready-made gym app?

Yes. The ready-made gym app starts free in about 5 minutes with members, plans and renewals, and you change it by asking in the chat.

Can the gym app remind members before their membership ends?

It shows who is due and opens WhatsApp with the reminder ready; the desk taps send. It doesn't send messages by itself.

Can members check in with a QR code at the gym?

Yes, if you ask for it: the installed Android app on the desk phone can scan a member's QR code with its camera (not in the web link). It doesn't connect to turnstiles or separate scanner machines; members can also be marked in from the check-in screen.

Can trainers give diet charts through the app?

Yes. Each trainer can add a workout or diet chart for a member, and it can be shared as a PDF or seen by the member after sign-in.

Can members pay renewal fees in the app?

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

Can I put the gym app on Google Play?

Yes, from your own Google Play developer account with a paid AppCub plan. AppCub's team can do the Google Play steps for a fixed quote.
