Jetseen

I live across borders, and every tool I tried did one piece of the problem. A Schengen calculator that ignored my UK and UAE days. A tax-residency tracker that knew nothing about my visa expiries. A spreadsheet I kept forgetting to update. None of them could answer the one question that actually kept me up at night: across every country, where do I stand right now?

So I made the app I wanted. Jetseen tracks your days against the rules that matter at once, Schengen 90/180, the US Substantial Presence Test, the UK Statutory Residence Test, UAE residency, 13 in total, and shows days used, days remaining, and your status at a glance. It tracks both directions, staying under a limit or hitting a minimum to keep residency. It keeps your visas with their expiry and max-stay per entry. It logs every trip on a calendar and a timeline, and exports clean records when an accountant asks. All of it manual entry, stored only on your device, no GPS.

Then I started showing people, and it turned out a lot of others were stuck with the same scattered tools and the same quiet worry. The demand made it clear this wasn't just my problem to solve.
