You forget.
Alter remembers.
A 42-question survey teaches Alter your rhythm,
so each notification carries one sentence only you would recognize.

A manual just for you
Chronotype, focus duration, procrastination pattern, depth of relationships. Built on 12 behavioral psychology frameworks, Alter assembles a manual for you, just you.
No two pushes alike
Afternoon-type? 1–3 PM gets conclusions only. Procrastinator? "Just one thing, right now." Tone shifts automatically for promises, exams, funerals.
Answer once, Alter learns
Tap "Nailed it / Tight / Passed" once. Alter adjusts the intensity and timing of the next reminder.
Apple & Google Calendar sync
Keep using the calendar you already use. Alter does not move your events.
Weekly "What Alter sees in you"
Every Sunday, Alter shows what it has learned about you in one screen. Correct anything that feels off on the spot.
