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.

ZenLocks helps you put your phone down and return to the life in front of you. Not every quiet moment needs another scroll. Morning coffee with your partner, an afternoon with your child, a patient conversation with your parents, or a few minutes alone with your own breath. ZenLocks turns focus into a clear commitment: choose a duration, start a session, and let system-level blocking keep distracting apps out of reach. Why ZenLocks - Strict focus timer: set a session and stay with it. - System-level app blocking: built on Apple Screen Time APIs to block selected distractions. - Deliberate exit friction: no simple cancel button during a session, so your first decision has a little more weight. - Focus stats: see your sessions, streaks, and reclaimed time. - Privacy first: your focus data stays on device and can sync through your private iCloud account. - No ads, no third-party analytics, no tracking. ZenLocks is not here to punish you for using your phone. It is here for the moments worth protecting: love, family, rest, deep work, and the quiet attention you keep meaning to give back to yourself. Lock screen, unlock life.
