School Planner App That Handles A/B Weeks

A paper planner has one thing going for it: everyone gets one. What a school diary can’t do is tell you that this is a Week B, that Tuesday’s Chemistry has moved to the lab, or that the assignment set two weeks ago is due tomorrow.

Weeklie is a school planner built around the part most apps get wrong — the shape of the timetable itself.

Timetables that don’t repeat weekly

Plenty of schools run something other than a plain Monday-to-Friday week that repeats:

• A/B or fortnightly weeks, where two different weeks alternate all term
• Block scheduling, with fewer, longer lessons on a repeating pattern

A generic calendar app can represent any of these, but only by making you enter every single week for the whole year. Weeklie stores the cycle instead: set how many weeks it repeats over, fill each one in once, and the app works out which week today falls in. If a holiday shifts the pattern, correcting it is one setting rather than an evening of re-entry.

It supports cycles of up to four weeks, which covers A/B weeks, three-week and four-week rotations. A cycle has to be a whole number of weeks, so a six-day rotation is outside what it can model.

Homework attached to the lesson it came from

Assignments live with due dates and get ticked off when they’re done, so nothing is discovered the night before.

Reminders come in two kinds: before a lesson starts, and before an assignment is due. Both are set per item rather than globally, so the app isn’t generating a stream of notifications that get swiped away unread. Reminders and photo attachments are part of the one-off purchase.

On the home screen, not in another app

The widget is the point. Today’s lessons appear on the home screen of an iPhone or Android phone, so checking what’s next doesn’t mean unlocking the phone and opening anything. There’s an Apple Watch app for the same reason, and Siri can answer “what’s my next lesson?” without the app being opened at all.

For most people, the app is something you fill in during the first week of term and then rarely open again.

What it doesn’t do

Weeklie tracks lessons and assignments. It doesn’t record grades, exam results or attendance, and it isn’t a revision timetable — if that’s what you’re after, this isn’t the right app. Keeping the scope narrow is why the timetable part works properly.

Free, offline, and without an account

There’s no sign-up. Your timetable is stored on your device, which means it works in a building with no signal and there’s no account to lose. The timetable, homework tracking and the widget are free, with ads; one optional purchase, paid once, removes the ads and unlocks reminders and photo attachments.

Weeklie has been on the App Store since 2014, and the app itself is fully translated into 12 languages.
