Browse data sources

26 sources publishing 266 distinct metrics into one shared namespace. Names shown in this colour are written by more than one source — they land on a single series, with each source’s contribution still identifiable. Each card also notes what connecting takes and which sources stay in the permanent free tier.

Ask for a source

Sources authenticate as you, so a new one only needs an account you already have — there is no partner agreement to negotiate and no approval to wait for. That is why this list grows in weekends rather than quarters, and why requests that other trackers close as impossible are usually just unwritten here.

Everything below is asked for, on the way, or — in one case — already answered by a source that carries a condition worth reading first. Sources ship to everyone at no extra cost, because there is only one plan.

Ships today, with a catch

  • iOS Screen Time

    Ships today, with a catch

    Ships as the Screen Time source above: the phone measures itself and the companion app sends the numbers, so there is nothing to install and no second machine in the chain. The catch is fidelity. Apple's Screen Time API will not hand any app the exact figures, so an iOS minute count is a floor rounded down to a fixed step — 45 means at least 45, under 50 — and it covers what the OS agrees to release rather than every app. How often you opened an app never leaves an iPhone at all.

    235 votes on Exist.io, closed there as not possible. Apple Developer Technical Support confirmed in March 2026 that the extension holding the exact numbers is sealed, and it still is; what changed is that the monitor extension next to it is not, which is enough for a coarse total.

On the list

  • YouTube

    On the list

    Watch and search history, by Takeout export and the Data API — the same two-route shape apple_health already uses.

    The most-requested integration Exist.io has ever received (312 votes), closed there as not possible.

  • Bank transactions

    On the list

    Balances and spending straight from the bank over SimpleFIN, alongside the Lunch Money sources rather than replacing them.

    Exist.io's second-highest integration request was Mint, at 250 votes; Mint itself has since been retired.

  • Android screen time

    On the list

    Per-app usage from Android's usage-stats permission, collected by the companion app the way it already syncs health data. Exact minutes and app-open counts, both of which an iPhone withholds.

    The half of the 235 votes Exist.io received for phone usage that Apple's sandbox cannot answer honestly. The Screen Time source already accepts this data; the Android half of the companion app is what is missing.

Not planned

  • Desktop screen time

    Not planned

    Not planned. Screen time here means phones: the collector is the phone itself (ADR 0143), which measures its own use with no second machine in the chain. A desktop needs an always-on agent on every computer you use — RescueTime and ActivityWatch both do it, so this is a scope decision rather than a technical wall. The rescuetime source was removed in August 2026 and is not coming back.

“On the list” means exactly that — it is not a date. “Can’t be built” means the data has no route off the device or out of the vendor, and the reason is written next to it rather than left for you to guess. “Ships today, with a catch” means a request that has been answered, with the catch spelled out where the request was made.

Honest correlations need months of overlapping history, so the best time to start collecting was months ago. The second best is now.
