@leofluxTidemark is the most niche productivity app I've used in years and I cannot put it down. It takes your habits — gym, journaling, deep-work blocks — and schedules them around the sun + tide phases of where you live. Hard to describe why it works but it just does; the body knows the rhythm and the app stops fighting it. UI is gorgeous, sync is instant, no ads. Three weeks in, my streak is at 19 days, the longest I've ever held. Recommend. #ad
