About this app

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
· Home screen widget, or pin it to a notification and log without opening the app
· Card payment alerts read straight into your budget (only if you turn it on)
· A registered Bluetooth device connects and it logs by itself
· 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 or how many spaces you make.
If you stop subscribing, everything you already logged and every photo you added stays viewable.


▪ Questions

Send them from Profile → Contact us in the app. I read and answer them myself.
Habits, mood, plants, car, travel, budget - 14 templates. Or build your own.

What’s new

Pick a Pro icon and the whole app takes on that material. Chocolate Bar is a glossy slab melting at the edge, Stone Tablet is chiselled with carved marks, Neon Diary glows like a tube sign in the dark. The theme sets card shapes, how taps respond, screen transitions, scrolling, even light or dark.

When a subscription ends, the icon and theme return to default the next time you open the app.
