The web app

app.interstatetracker.com is the same account in a browser. It does not record — that is the phone’s job — but it is where you claim road you drove before the app existed, edit trips, download your data, and sign a device out.

An account is optional. A phone that never signs in keeps everything locally and sends nothing.

Logging in

The page is headed Log in, and the Sign up control on this site reaches the same page. Type your email address and choose Email me a sign-in link. Opening the link logs you in, and creates an account if that address doesn’t have one yet: there is no account to make first, and no password.

A link is good for one use and 15 minutes. Opening it brings up a page with a Log in button, and pressing that is what spends the link — so a mail scanner that opened it first has not used it up. If the page says “This link has expired or has already been used”, ask for another.

Once you are in, Settings, then Passkeys, then Add a passkey puts your fingerprint, face or screen lock in place of the inbox on that device. A passkey’s private half never leaves the device it was made on.

The phone signs in its own way: an email address and a six-digit code, in the app’s own Settings.

The screens

• Dashboard — the headline figures, recent achievements, recently clinched stretches, the routes closest to done, and a breakdown by state. Reached by the wordmark at the top of the page.
• Map — your coverage drawn on the Interstate network. The key names every line by shape as well as color, and Showing filters the map to all credited travel, GPS-verified only, or manual claims only. There is no basemap behind it and no map tiles are fetched: the roads and your coverage are the whole picture.
• Routes — every route in the release, with clinched miles, total miles and share. Open a row for the state-by-state breakdown, that route’s drives, and its exit-to-exit ledger.
• Trips — every trip on the account, with its date, evidence, miles, stretches and whether a trace is held. Rename a trip, write notes on it, delete it, or open its trace.
• Awards — the achievement catalog by category, unlocked and locked, with progress on the ones in reach.
• Add a claim — road you drove but never tracked. See below.
• Settings — your account, passkeys, signed-in phones and browsers, your exports, Delete account, and a light-theme switch.
• A state’s page — the same figures and route roster for one state, reached from a state’s name on the dashboard or a route row.

A footer runs under all of them: this site, the privacy policy, donate, and Report a problem. That last one is the browser’s version of the phone’s form: type what happened and press Send, and nothing is gathered or sent before you do. It does not name your account, so a report you want answered needs a way to reach you in the message.

An edit made with no connection waits in that browser and goes up when the connection returns. Signing out discards anything still waiting, and warns you first.

Adding a drive by hand

Add a claim records road you drove before you started tracking. Four shapes of claim:

• Whole route — every state a route runs through, end to end.
• State section — one route through one state, end to end.
• Measure range — part of one route through one state, by route measure.
• Between places — a start and an end place. The network proposes the Interstates between them and you edit the rows before recording.

Record claim writes it. A claim counts toward your Interstate miles the same as a recorded drive, and it stays labelled Manual claim wherever it appears: how a mile was earned never stops being visible.

Measures in the claim form run from the state line and are marked ≈: they are route measure, not mileposts.

Trips, traces and deleting

A trip’s row on Trips shows whether a trace is held for it, how many points it has and what it spans.

Delete the trace, keep the trip erases the line and keeps every mile that trip earned. It is permanent in a particular way: a trip with no trace can never be matched again, not by a better matcher and not by a better map.

Delete removes the trip itself — its miles, the coverage it credited, and its trace — from your account and from every signed-in device on its next sync.

Your data

Settings, then Your data, has three downloads:

• Everything, as JSON — the complete copy.
• Trips, as GPX — one track per trip.
• Coverage, as GeoJSON — one line per clinched stretch.

Importing and exporting says what is inside each one. There is no import in the browser; GPX files are imported on the phone.

Phones, browsers and passkeys

Settings lists every phone signed in to the account, every browser with a live session, and every passkey, each with when it was added and last used. Any of them can be revoked there, and revoking a phone stops it syncing until it signs in again.

Only a signed-in browser can revoke; the phone app cannot. If you lose a phone, revoke its sign-in here.

Delete account

Delete account, under Your data, takes the whole account in one step: trips, traces, claims, achievements, passkeys and every signed-in device. There is no undo and no grace period. Trips still stored on a phone stay on that phone.

Your data is the short version of what is held where; the privacy policy is the long one.

What it can’t do

It doesn’t record a drive, and it doesn’t import a file. The footer’s Report a problem is where something you found in the browser goes; getting help is the longer answer.
