Three steps, about five minutes.

1. Install it on your phone.

WhatNext.Pro is a web app — no App Store, no download. Open whatnext.pro on your phone, tap “Add to Home Screen,” and it lives on your phone like any other app.

2. Enter your dates.

Read the dates off your own documents — your visa, your 90-day slip, your passport, your licences — and enter them. The app suggests which reminders to set based on your visa type, but you type in every date yourself. It never fills one in for you.

3. Get reminded — early, and twice.

Each deadline nudges you 30, 14, and 7 days out, by push notification and email. Even if a notification gets swallowed by your phone, the email still lands, and every reminder waits for you in the app’s inbox. One tap adds any date to your calendar.

The one rule that shapes everything

You tell WhatNext.Pro your dates. It never guesses, calculates, or advises — it simply makes sure you see them coming.

That’s deliberate. It means the app is never wrong about the rules, because it never claims to know them. It’s a reminder you can rely on, not advice you have to double-check.

What you can keep track of

90-day reports · visa extensions and expiries · passport renewals · health insurance · car and motorcycle licences · vehicle registration and insurance · Thai tax filing · US tax / FBAR · plus any custom “name it, date it” reminder you want.

Your vault, on your phone

Snap a photo of a document and it’s stored — encrypted — on your phone only. Nothing uploads. Because it lives on your device and not our servers, only you can open it, and you can export a backup copy any time. (If you delete the app, the vault goes with it — so keep an exported copy somewhere safe.)
