SuisTesJ

The J method

It remembers when you learned. It tells you when to review.

You note the date of a class. The J method lays down the seven review dates; the app tells you, every morning, what falls today.

The Today screen of SuisTesJ: the day's progress, the next seven days, and the first review due.

The scale

The gaps widen

Seven marks counted from the day of the class. The app holds the scale; all you need to know is which one falls today.

  5. J14+7 d
  6. J30+16 d
  7. J60+30 d
  8. J90+30 d

A Monday class falls on a Monday again at J7 and J14. That is arithmetic, not a design intention — but it is convenient.

Every morning

One question

What do I need to revise today? The app answers with a list. Nothing else asks you to decide.

And if you miss a day?

8:12
The Calendar screen of SuisTesJ: August 2026, with days needing attention, today in progress, and planned reviews ahead.

Three steps

Then nothing left to decide

  1. 01

    You note a class

    A title, a subject, the day you had it. Under a minute.

  2. 02

    It lays down the dates

    The seven marks from that day. An exam you enter truncates the series.

  3. 03

    It tells you what's due

    Do it, or push it back. Nothing moves unless you accepted it.

Your data

Without an account, nothing leaves the phone

No analytics, no tracker, no server. The whole app works in airplane mode.

If you turn syncing on, your courses and dates are stored in Switzerland, in Zurich.

What Cloud is

8:12
The Settings screen of SuisTesJ: local mode, saved on this device, and Cloud presented as optional.

Download

Coming to both stores

The app is in closed testing. These two slots will become the official badges, in the same place and at the same size.

  • Google PlaySoon
  • App StoreSoon

Meanwhile, the browser is enough: the Web app is live, for Cloud accounts.

The closed beta needs twelve testers

Google requires fourteen days of closed testing before any release. If you are on Android and want the app before everyone else, write — one line is enough.
