10 micro apps you can build on your phone while sitting in your car or on a coffee break. No coding. No laptop.
Starting with a daily expense tracker.
Here’s the exact prompt:
Build me a mobile-friendly daily expense tracker. Let me add an expense with an amount, a category (Food, Transport, Bills, Entertainment, Other), and an optional note. Show my total spent today at the top with a clean bold display. Show a scrollable list of all today’s expenses below with a delete option for each entry. Include a simple category breakdown showing each category as a share of today’s total with progress bars. Save all my data using window.storage so it is still there when I come back. Clean minimal design with plenty of white space, easy to use on a phone.
Now build your own.
