What you struggle with (staying focused, forgetting, planning, rushing into mistakes, reading and writing), how much time you have, and when you want to train — your daily set is built from that. ・Trainings that match your struggles come first ・Your daily amount follows the time you have ・Reminders are set for the time you chose ・Redo it anytime from Settings ◯ Built for adults who struggle to stay consistent ・Sessions start at 10 seconds ・Quiet by default — no pressure notifications ・Daily completion stamps ・Streaks won't shame you if you miss a day ・Ad-free, distraction-free ◯ What users say "I can finally keep a habit."
