What it measures
Everything Heurika tracks, what it reads automatically, and what it still has to ask.
A wristband counts two or three things well and calls the result your health. Heurika assesses seven dimensions and reads them as one system, because a short night shows up in tomorrow's appetite, and a heavy week of sitting shows up in how you sleep.
Every reading is a short scale in plain words, never a free-typed number. You are choosing between things you can actually judge, so the data stays honest.
How weighting works
Readings are not equal. Each carries a weight reflecting how much it actually moves your health, so the arithmetic matches reality rather than treating every line as the same size.
A doughnut costs more than a missed vegetable. Ten hours seated costs more than a short day outdoors.
The readings
How rested you feel is not something a sensor can know, so Heurika asks. Everything else it reads.
If you log food anywhere, three of these arrive on their own. The other two nothing measures.
Read from workouts, exercise minutes and active energy, and measured against what your week actually called for. A walk on a rest day counts in full.
Read from heart rate variability against your own recent baseline, never against anyone else's. Absolute figures mean nothing across people.
iOS keeps detailed usage private, and rightly. Heurika asks instead, or reads only which threshold you crossed on apps you pick, and never learns which apps they were.
Both come from a watch if you wear one. Daylight in particular does more for sleep than most people expect.
How readings arrive
Connect what you already use and most of the day is taken before you open the app. What is left is what no sensor can see.
One connection
Around forty six apps write into it, so connecting it once brings in all of them. MyFitnessPal, Cronometer, Cal AI, Lose It, Peloton, Nike Run Club, Hevy, AutoSleep, Sleep Cycle, Calm, Headspace, Garmin, Oura, Whoop, Fitbit and most wearables.
Coverage
9 of 14 readings
One connection
Whatever you sync to your phone, whether that is Apple, Google, Outlook, Fantastical or Notion. Heurika reads when you are committed and plans training around it, without being asked.
Event names stay on your device unless you choose otherwise. Times are enough to schedule around.
Direct
Every ride and run with the full activity detail, counted by moving time rather than elapsed, so waiting at a junction is not recorded as training.
Google Health, WHOOP and Oura are next.
A watch, a ring and a sleep app will not agree on last night. Heurika takes the most reliable reading, breaks ties by whichever is most recent, and treats anything you state yourself as final.
Correct any reading and it stays corrected. Later syncs will not quietly overwrite it. You know if you were awake at three.
It covers all seven dimensions, then asks what you are actually trying to change.
