Build a mobile app turning photos and voice into reminders

The poster built Loopi, an app that turns photos, text and voice into reminders, notes and expenses, in about 45 days using Replit and AI agents.

What they did

The poster used Replit and its AI agents to build Loopi, a mobile app that takes a photo, pasted text, or voice input and turns it into reminders, notes, and expenses. They say they had no prior mobile app development experience, used TestFlight for over a month with a handful of testers plus their own daily use, and stepped in to judge the agents’ output because earlier agents could overdo changes or break things.

How it went

Loopi reached a live App Store release in about 45 days. The poster says coding was not the main bottleneck; App Store submission, in-app purchases, reviews, and iteration around release slowed things down most.

Worth knowing

They estimate spending about $500 on Replit for Loopi, and say the app was tested extensively for over a month before publishing.
