Most tracking apps make you write in boxes someone else decided on. ProofKit works the other way round. You pick the buttons and cards, and build the way you want to keep records. What you end up with is a record book that exists nowhere else. Start on your own and keep it to yourself, or send one link and keep it together with family and friends. ▪ Want to start right now? 14 templates are ready Basics - Shared car · Travel · Budget Family & care - Childcare · Pets · Caregiving · Plants Health & habits - Workout crew · Diet/weight · Habit challenge · Mood diary Groups & home - Meetups · Household chores · Couples Pick one and the buttons and summary cards are already laid out, so your first record takes no setup. ▪ Not there? Build it Make a button (name, icon, color, recurring reminder), then choose the cards that summarize what you logged. Last record / who did it how many times this week / totals / ranking / streaks / days since / goals / trends / full history - nine card types to choose from. Keep the template to yourself, or publish it to the market so other people can pick it up. You can bring in other people's templates too. ▪ On your own Drinking water, days since your last cigarette, today's mood, when you last watered the monstera, your weight. One tap and it's logged. From the home screen widget it's logged without even opening the app. Streaks and days-since show up on cards, so you can see it at a glance. ▪ Together Send the invite link over a messenger. It expires after seven days on its own, so nobody wanders in later through a link left in an old chat. Who did what, and when, stays exactly as it was logged. Trip costs and household spending are split by person and category automatically. People you invite pay nothing. ▪ Records don't get rewritten You can't quietly change a record after the fact. If you got it wrong, you log a correction, and it sits next to the original. On your own that's proof you really did it that day. Together it's where you look when people remember it differently. ▪ Logging shouldn't be a chore · One tap logs it, with no form to fill · Log from the home screen widget without opening the app · For the car, it asks after the drive ends before saving - it never saves without asking ▪ ProofKit Pro (monthly or yearly) · 11 more templates, plus building your own and the template market · Attach photos to records · Restore a deleted space within 30 days · Six app icons, with the app's colors changing to match · No ads Yearly costs less than monthly. Check the store for the price where you are. Text records stay free, with no limit on how many you keep.
