How to make an app for a swimming pool

A swimming pool sells passes for hourly batches, each with only so much room in the water, plus a rush of summer courses. An app at the gate shows whether a swimmer's pass is valid, how full the batch is, and which course students have paid, without a thick register.

Updated 2026-11-09

Who uses the app

The office or gate staff, usually on one phone, with the data on it. If the office and the gate use different phones, or members check their own pass, connect your own Supabase database so everyone sees the same members.

The screens a swimming pool app needs

Batches: Each hourly batch with its group, such as ladies or kids, its limit and the number booked
Members: Name, phone, photo, batch, pass type and valid-till date; children with a parent's phone
Gate: Search a member by name or phone; see pass valid or expired and mark them in
Courses: Summer and learn-to-swim courses with students, days attended, coach and fee paid
Renewals: Passes ending this week or already expired, with a WhatsApp reminder button
Payments: Fees by day and month, by pass type and course

Features worth asking for

Batch limits, so the office stops adding swimmers once a batch is full
A gate screen that shows the member's photo and whether the pass is still valid
Per-session entries for visitors who don't hold a pass
Course attendance and coach for each learn-to-swim batch
A renewal list with a WhatsApp reminder showing the pass end date
A pass or course receipt as a PDF to share on WhatsApp

Where the data lives

With one office phone, the data stays on it. If the gate and the office use separate phones, or members check their pass on their own phones, connect your own Supabase database; to sell passes and courses online, connect your Razorpay account too.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Batches, Members, Gate, Courses, Renewals.
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 swimming pool, and paste it into AppCub:

Make an app for my swimming pool, Neelkamal Swimming Pool in Bhilai. Screens: batches, members, gate, courses, renewals and payments. Hourly batches from 6 AM to 9 PM, each with a limit of 30 swimmers; ladies-only batches at 10 AM and 4 PM. Members have a photo, batch, pass type (monthly ₹1,200, quarterly ₹3,200) and valid-till date. Gate screen: search by name or phone and show valid or expired. Per-session entry ₹100. Summer courses of 21 days with attendance and coach. WhatsApp renewal reminders and PDF receipts. Blue and white colours.

Tips for a swimming pool app

Set each batch's limit to what your pool and coaches can really handle, and give AppCub that number.
Add a member photo when someone joins; it makes the gate check quick and fair.
Enter summer course batches before the season opens, so enrolments go straight into the right batch.
Keep children's details private, and save the parent's phone for messages.
Run a busy summer evening with test members before moving your register in.

Good to know

AppCub doesn't connect to turnstiles, card readers or QR scanners at the gate, and it sends nothing by itself. Staff search the member on the gate screen and tap the WhatsApp button for reminders.
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 the app stop a batch from getting too crowded?

Yes. Give each batch a limit, and the batches screen shows when it is full so the office stops adding swimmers.

Can the gate staff check if a pass is still valid?

Yes. Search by name or phone on the gate screen, and it shows the member's photo and whether the pass is valid or expired.

Can members scan a QR code at the gate?

Not with a gate machine: AppCub doesn't connect to scanners or turnstiles. If you ask for it, the installed app on the staff phone can scan a member's QR code with its camera, or staff search the member by name or phone.

Can I manage summer course enrolments in the app?

Yes. Each course has its students, coach, days attended and fee paid, separate from regular passes.

Can parents pay for the summer course in the app?

Yes, if you connect your own Razorpay account and a Supabase database. The money goes to your account.

Can I keep a record of water testing and cleaning in the app?

Yes. Ask for a simple log screen with the date, what was checked or cleaned and who did it.
