What’s inside

One sheet, one scan, the app does the rest

Here is what Check by Check actually does today. If it isn’t on this page, it isn’t in the app yet.

Three freshly printed A4 weekly sheets spread across a sunlit desk, next to an iPhone showing the app home screen, a pen and a cup of matcha.
Monday morning Print it once, then leave it on the table Pick the tasks, print one A4 page, put it where your child will see it.

Print a sheet that belongs to your home

One A4 per week

Tasks down the left, Monday to Sunday across the right, point values printed in the boxes. Up to 24 tasks fit on one sheet — a full week for one child.

AirPrint, or save the PDF

Print straight over AirPrint, or export the PDF and send it to a print shop or another device. Use A4, portrait, at 100% scale — not “fit to page”.

A line just for them

A short dedication can be printed along the bottom, and a rotating habit hint sits near the top. It’s paper — it may as well feel personal.

One photo closes the week

Recognition never leaves the phone

Black corner markers straighten the image, the QR code tells the app which printout this is, then each box is checked for ink. All of it runs offline.

Review before it counts

A scan never edits points on its own. The app lays the reading out day by day, flags the boxes it wasn’t sure about, and waits for you to correct and confirm.

Rescans post only the difference

The same sheet can be scanned as often as you like. On the second pass the app compares day by day with the previous reading, lists the newly filled boxes, and supersedes the old record instead of counting twice.

Filled boxes turn into visible progress

Ledger and rewards

Every credit and redemption stays in the ledger, always reviewable. You write the reward list yourself: half an hour more reading, a trip to the park, whatever your family values.

Weekly brief and trends

A short weekly note: how the week went, what might explain it, what to try next. Alongside it, trend charts by week and by month, plus a growth calendar.

Eight milestones

First sheet, first week past half, first perfect week, three weeks rising, starting again after a gap — eight markers tied to what actually happened, not badges to hoard.

Built for a household, kept in your hands

Several members, separate tracks

Each member gets a mascot, their own tasks, points and sheets. Adding two more chores for the older one leaves the younger one’s sheet untouched.

Share a template by QR code

A task set you like can be turned into a QR code and sent to the other parent or a friend. They scan it in the app and the same sheet is set up on their side.

Local by default, iCloud optional

Everything lives on this device by default. Pro members can turn on iCloud sync so an iPhone and an iPad share one record — through the private library under your own Apple ID, which we cannot read. Scan photos never take part in sync.
