$1K From a 24-Hour App (Built With AI)

  • Igor Cuiumju

  • Indie Developer, Seasonia
  • $990+ in sales in first 3 weeks

On February 1st 2026, Igor Cuiumju decided to run a small experiment.

He gave himself less than 24 hours to build and ship a very simple iOS app.

📝 From a recent interview…

There was no launch plan, no marketing budget – and honestly, no expectations.

The app is called Seasonia – all it does is show how much of the current season is left. ❄️🌸

A calm little widget on your home screen. No accounts, no subscriptions, no complex features.

He priced it at $0.99 and used AI tools throughout – for both development and design.

A few hours after launch, the app unexpectedly climbed into the charts.

Since launch, it’s consistently ranked Top 10 in its App Store category across several European countries 👀

As of today, he has 1,000+ paid customers.

Priced at $0.99, that’s $990+ in sales in just 3 weeks.

It’s not a massive success by startup standards, but considering it was built in under a day, it feels surreal.

What surprised me the most is how much people appreciate small, focused apps without subscriptions or noise.

Growth mainly came from App Store Optimization (ASO) – updating screenshots, descriptions, and keywords to rank higher in search.

A dead-simple app, built in a day, earning real money. What tiny app idea could you ship this weekend? 🤔
