A travel journal
Tie each entry to a place, not just a date. What the day looked like, sounded like, what it cost. What surprised you. A record you will actually want to read on a grey day back home.
Part of Innerholm+. $40 a year, or $5 a month. The free editions stay free because Plus pays for them.
No ads. No trackers. Nothing trains on what you write. Search across years, sync between your devices, and export everything as Markdown, Day One, or PDF whenever you like. How privacy works.
