When did I last water the plant? Walk the dog? Call Dad? Restock the office snacks? When was the last time I did...everything? "Just Did" answers one question: when did I last do that? No streaks to maintain. No habits to break. No guilt-trip notifications. Just a calm, simple log of the things you do, with optional gentle nudges. A minimalistic approach to logging task completions and to-dos. ONE GESTURE, ONE LOG • Tap and hold a task card to mark it done. The card fills as you hold — a small, satisfying confirmation. No accidental ticks, no forms, no checkmarks, no fanfare. It's a different feel from every other tracker, and it's the whole point. SET A CADENCE, OR DON'T • Add an interval to any task — every 3 hours, every 4 days, every 7 days — and "Just Did" will gently remind you when it's been a while. Or skip the cadence entirely and just keep a record. Reminders are always optional, never pushy. SHARED SPACES, FOR ANY GROUP THAT NEEDS ONE • Create a Space and invite anyone with a 6-character code — your partner, family, roommates, dorm-mates, coworkers, project teammates, or a group of friends. • See who did what, and when. No assignments. No nagging. No leaderboards. Just a shared sense of "yeah, that's been done." • Use it at home, at the office, in a shared studio, on a trip — wherever a small group needs to keep track of the same tasks or to-dos. FREE FOR MAJORITY OF USE CASES • Unlimited personal tasks on your device, free forever. Spaces are free for up to 2 members and 3 shared tasks — enough for some groups. • The Pro upgrades are honestly optional. • Tasks Pro — full display customisation: background packs, premium completion animations, custom card colours, personalised colour scale. • Spaces Pro — removes the member and task caps. The owner pays; everyone in the Space benefits without paying themselves. PRIVACY BY DEFAULT • Personal tasks stay on your device. Shared Spaces only sync what's shared. Sign in with Apple, Google, or email — or skip sign-in entirely and use JustDid locally. Just Did is for anyone who doesn't want another habit tracker. No streaks. No guilt. No pressure. Just a quiet record of the things you've already done — alone, or together.
