Simple Digital Loyalty Punch Card App for a Restaurant

Project Description:
I’m looking to create a simple, user-friendly loyalty punch card app for my restaurant. The app should allow customers to collect digital stamps each time they make a qualifying purchase (e.g., 1 stamp per full roll of sushi).

I prefer the app to be built using a no-code platform like Glide, Thunkable, or Adalo to keep costs low and allow me to manage updates easily.

Basic App Features:
Customer login via phone number or email

Digital stamp card showing progress (e.g. 0/10 stamps)

Staff can issue a stamp manually at checkout (via button or admin access)

When 10 stamps are reached, a reward is unlocked (e.g., free roll)

Simple interface with restaurant logo and theme colors

Customers can install the app on their phones (PWA or native app)

Preferred Tools:
Glide (preferred), Thunkable, or Adalo

Google Sheets backend (if using Glide) is a bonus

Deliverables:
Fully functional app (PWA or Android/iOS, depending on platform)

Admin instructions or short tutorial on how to manage and update it

Optional: help publishing to App Store/Google Play (if native app)

Budget:
Looking for a cost-effective solution under $100–$300 depending on complexity. Please include samples of similar apps if available.

Let me know if you have questions or need help deciding the best platform for this.
