Know exactly when to leave.

No. TransitTempo is an independent app built by one person. It isn't affiliated with, endorsed by, or connected to the Metropolitan Transportation Authority, the Port Authority of New York and New Jersey, or any transit agency. It uses the data those agencies publish openly.

Those apps plan a route anywhere in the world using the schedule the agency publishes. TransitTempo does one city and one job: it learns how your specific stops behave at the hour you travel, and corrects the arrival time accordingly.

The other difference is direction. Most apps answer “how do I get there?” This one answers “when do I need to leave?” — and then tells you, unprompted, at that minute.

A random account number, the nicknames you gave your places (“home”, “school”), the routes you built, and public stop numbers. Not your addresses, not your coordinates, not your name, not an email address.

If you switch on trip history, it also keeps the times of trips you complete so it can show you your own statistics. That's off by default, and turning it back off clears what was kept.

No. The app creates an anonymous ID on first launch and gives you a recovery code to save. That code is the only way to move your setup to a new phone, so keep it somewhere safe — we can't reset it for you, because we don't know who you are.

Build it yourself. The route builder lets you choose each leg — the stop you board, the line you take, where you get off — including the odd shortcut no routing engine would suggest. Once saved, it's treated exactly like any other route.

Subway, all five boroughs of MTA bus, and PATH.

Notifications are the product — without them the app can't tell you when to leave. Location lets it follow a trip in progress, time your transfers and power Go Home.

Each permission is asked for separately, with a plain explanation, and you can decline any of them. Anything the app can't do without a permission you declined is hidden rather than left on screen as a dead end.

Everything runs through the Discord server — join it and you'll get a TestFlight invite from there. It's also where bugs get reported, where the weekly reliability figures are posted, and where you can ask for a route or a feature.

Nothing during the beta. If a paid tier arrives later it'll be announced clearly and in advance — and the privacy design described on this page isn't something a subscription would change.

Honestly, less accurate than it'll be in a month. A route through stops with plenty of measurements is corrected precisely; a brand-new one starts from the published schedule and improves as observations accumulate. The app marks which is which, so a number you should trust looks different from one you shouldn't.
