Why every app here is a map, not a log.

Dev and the mood app
Dev — sixteen, a rough few weeks, a friend recommending a mood-tracking app with a big streak counter
The app looks friendly: tap an emoji a day, keep a streak, watch a mood graph climb. Dev's friend swears it helped. Dev opens the app store page, thumb over "Get".
Some of what the app promises is real: noticing that a mood dips every Sunday, or lifts after a run, is genuinely useful, and naming a feeling has a small steadying effect on its own.
But the streak is not for Dev — it is for the app. And when you are already low, checking in on how bad you feel, day after day, can deepen the low instead of lifting it (that is rumination, and a tracker can feed it). The rawest data about you would also leave the device.
The honest answer is not "trackers are good" or "trackers are bad." It is: what is this one optimising for, and is that what YOU need right now?
What does Dev do?
Should you track your feelings? It depends — on the design, the reason, and you. That is exactly why every app here is a map, not a log: we teach you to decide, and we keep nothing.
