Notes
Notes that live where they belong
Attach a note to a single occurrence, or step back and write one for the whole day, week, or month. Your reflections stay next to the thing they're about.
Switched to the lighter roast — way less bitter than the usual one.
Slept badly, skipped the run. Moved it to tomorrow morning.
Cut coffee to one cup a day. Headaches on day two, fine after.
Best running month this year — 62 km total, zero knee pain.
Metrics
Measure habits down to the last detail
Give any habit its own metrics and fill them in as you log. Eight types cover everything from grams and minutes to gut feelings — and numeric ones add up per day, week, and month.

Keep count of the things your habits use
Some habits consume real, countable stuff. Add a stock — a bag of beans, a box of gels — and Habitrack depletes it automatically every time you log, prefilling your metrics with each item's defaults.

Costs
Know what a habit really costs
Every log inherits its cost from the stock it consumed. Habitrack adds it all up per habit and per day, week, and month — in every currency you buy in.
