Original Summary

Hey everyone, I spend a lot of time traveling around Europe and always hated trying to calculate the Schengen rolling 90-day window in Excel. Half the time I was worried I miscalculated an entry date or risked an overstay. So over the past few weeks, I vibecoded a small Android app called viflo to handle this properly. What it does: - Accurately tracks the rolling Schengen 90/180-day rule so you always know your remaining days. - Counts days per country to keep an eye on the 183-day tax residency threshold. - Keeps a clean chronological log of all your past trips and border crossings. - "Travel Footprint" card: Generates a sleek, visual summary of all the countries you've visited, formatted to share on social media. How it was built: Mostly vibecoding with Google AI Studio / Gemini. The stack is a lightweight web core + Tailwind, Firebase Firestore for sync, and packaged as a Trusted Web Activity (TWA) with Google Play Billing integration. Honestly pretty surprised at how far you can take a production app with AI prompting once you dial in the core logic. The basic tracker is free, and it just went live on Google Play: https://play.google.com/store/apps/details?id=app.vercel.visaflow_mu.twa Would love some honest feedback on the UI and flow. Also happy to answer questions if anyone is curious about the vibecoding process or shipping a TWA to the Play Store.   submitted by   /u/ozguryaman [link]   [comments]
