Set up your diary once, before you qualify

Most trainees start with a paper diary or the notes on their phone, then move everything when they qualify. Start in Lesson Diary and there is nothing to move: your pupils, lesson history and progress records stay in the same account when you become an ADI. A free account needs no card, so you can try it on real pupils first. Already qualified? See the ADI diary.

Your week in one place

One-off and recurring lessons, with a warning when two of them clash.

Notes after every lesson

Record what you covered against the DVSA syllabus while it is fresh, and see what each pupil needs next.

Every pupil on record

Contact details, lesson history, test dates and what they owe, all one tap away.

Nothing to move when you qualify

Pass Part 3 and carry on in the same account. Add your ADI badge number and keep every pupil and record.

See the diary in action

Your week and your pupils on one screen, on the web and in the apps.

See the gaps before they cost you

A free hour between two lessons is lost income. We flag it on your diary so you can fill it — or bin it and go home early.

Common questions

Can a PDI use Lesson Diary?
Yes. If you teach pupils on a trainee licence, you can run your diary, pupil records and progress notes in Lesson Diary, the same as a qualified ADI.
Is Lesson Diary free for PDIs?
There is a free account for every instructor, with no card needed. It is a limited version of the diary. The full plan is one price for everyone, and new subscribers get a free trial first.
Do I need an ADI badge number to sign up?
No. You can leave the badge number empty and add it when you qualify.
What happens when I qualify as an ADI?
Nothing changes. You keep the same account, the same pupils and the same records.
Is there an iPhone and Android app?
Yes. The full diary works in any browser and in the native iPhone and Android apps (Android on request).
