Browse data sources

19 sources publishing 156 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 — many sources need no key at all, and where an upstream only offers a personal API key, the chip says so.

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 — if you own a Mac. Apple's own Screen Time API is still sealed inside a sandbox that may display the numbers and nothing else, so the route goes around it rather than through it: your iPhone and iPad hours sync to your Mac through iCloud, and the screentime exporter reads them there and writes a CSV you upload here. That means an exporter to run, Full Disk Access to grant it, and iCloud Screen Time sharing switched on — not a toggle in an app store. With no Mac in the chain there is still no route off the phone.

    235 votes on Exist.io, closed there as not possible. Apple Developer Technical Support confirmed the sandbox in March 2026; what changed is the detour, not Apple's mind.

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.

    The half of the 235 votes Exist.io received for phone usage that no Mac detour reaches. RescueTime covers the desktop, and the Screen Time source now covers Macs, iPhones and iPads.

“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.
