Don't let yourself forget what you want most.
People forget even the thing they want most. binta reminds you of the goal you set through periodic notifications (a "slap").
Every time you remember, a little more of your day goes to that goal — a quiet, sometimes blunt, reminder.
Free to use. "binta Pro" (300 JPY/month or 1,800 JPY/year, auto-renewing — local equivalents apply in other regions) unlocks all looks, unlimited scenes, several goals at once, record analysis, and "words to yourself."
