Five things, and nothing that nags you about any of them.
One short affirmation, written to you rather than at you, at a time you pick. Free accounts get the morning letter; premium adds midday and evening, each at its own time.
A private journal, with voice memos when typing is too much. Free accounts can write for their first three weeks; premium is unlimited.
Rate the day with one tap — radiant, bright, steady, heavy, storm. Over months it becomes a calendar of how the year actually went, which is something a streak counter can never show you.
Every letter is set on stationery: cream, kraft, ledger, ruled. Three papers are free and the rest come with premium.
Write lines in your own words and have them come back to you on your own schedule. Premium.
No streaks. No badges. No notification telling you that you broke something. Miss a day and the next letter arrives as if nothing happened.
