Tubbie

The platform board for your pocket.

You already know the route. What you need at 8:47am (standing at the top of the stairs, or even before you leave your house) is one answer: is my train coming?

Tubbie shows what your station's board shows. Every line, every direction, the way the platform boards do it. On your Lock Screen while you're walking. In a widget while your phone sits on your desk. Without opening anything.

FEATURES

• Board view: every train at your station, grouped by line and direction. Bakerloo, Central, Circle, District, Elizabeth, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria, Waterloo & City, DLR, and the six named Overground lines.

• Lock Screen Live Activity: tap a train and the countdown appears on your Lock Screen and in the Dynamic Island. When the train is gone, the activity ends itself — no stale countdowns, no manual cleanup.

• Home Screen Arrivals widget: pick a station and a direction; it shows what's coming next, with a per-station direction picker that learns which directions your station actually serves.

• Home Screen Status widget: every line's disruption state at a glance, so you see trouble before you leave.

• Lock Screen widgets: accessory widgets (rectangular, circular, and inline) so the next train is visible on your Lock Screen even without a Live Activity running.

• watchOS companion: the station arrivals board and the soonest upcoming train, right on your wrist. Requires watchOS 10.0 or later.

• Watch complications: four families — circular, corner, inline, and rectangular — each showing the time until the next train with a per-second countdown on the watch face.

• Status view: every line, every disruption status, before you go underground and find out the hard way.

• Four themes: classic amber, orange, white, and a high-contrast theme designed for outdoor reading and low-vision users.

• iOS 26 fluid tab bar with Liquid Glass refractive lensing (degrades cleanly to a Material pill on iOS 17–25).

PRIVACY

The platform board at your station doesn't need your email address. Neither does Tubbie.

No accounts. No analytics SDK. No crash-reporting service. No advertising network. No third-party trackers. No push tokens sent anywhere. There is no server that knows you installed this app.

Your TfL API key lives in the iOS Keychain and talks only to api.tfl.gov.uk. Location is requested once if you tap "Find nearest station," used immediately, and never stored.

SETUP

Tubbie uses the free TfL Open Data API. Get a key in two minutes at api-portal.tfl.gov.uk, paste it into Tubbie's settings, and the board lights up. The same key powers the Live Activity, widget, and Status view.

If you're visiting London and need routing help, Citymapper will serve you better. Tubbie is for commuters who already know the way.
