Solo-built app just passed a bigger competitor on Google Play visibility score https://preview.redd.it/cmy3haru6veh1.png?width=1510&format=png&auto=webp&s=6c9f05bd5d22a012f123e4c4f6f26d1a7c85c5e3 Sharing this because it's a small win but it's mine.

I'm a solo dev and I just launched something I'm genuinely proud of 🧵 — AI document parsing with confidence scores Here's the problem it solves: Every day, finance & ops teams manually re-type data from invoices, receipts, and purchase orders. It's slow. It's error-prone. And it scales terribly.
