Only kept sessions count. Faded ones feed nobody.
Everything that matters is free. The key unlocks the other colours and a second dragon, and it is how this stays free for everyone else.
A focus timer. You choose a length, you stay with it, and a small dragon is fed by the minutes you kept. If you leave the app while the ember is lit, the session fades. That single rule is the reason timers like this work: the cost of checking your phone becomes visible.
It makes no claims about productivity, attention or anything else. It is a creature that is hungry when you are distracted.
Everything stays in this browser on this phone. No account, no server, no analytics inside the app. Export a file if you change phones.
