A budget app called TapSheet has hit 9K downloads in about a month.
What makes it interesting is that it did not start as an app at all. It started as a simple Google Sheet built to track expenses, then slowly turned into an app once the distribution proved there was demand.
The whole thing is built and marketed by a solo founder, Avian Jonas Leung.
He runs both Instagram and TikTok and posts around twice a day on average.
Before TapSheet became a standalone app, the workflow was pretty much an iPhone shortcut connected to Google Sheets.
Back then he posted a video showing the setup and it hit 600K views and 11.6K saves. The high amount of saves showed that people had interest in his system.
Since then, his content has reached about 3.1M total views, and the shift to an actual app gave him recent virality.
On February 21, 2026, he hit 1.7M views with:

The only open question is monetization. He appears to be running a subscription model, and budgeting audiences are notoriously price sensitive.
