  • Who's test ready

    A readiness score out of 5, from all 27 skills of the DVSA's driver's record. Calculated, never typed in.

  • What's next

    Today's lessons in order, each with its focus and pickup postcode.

  • Who owes what

    Unpaid lessons add up on their own. Review them, then send a polite reminder in one tap.

What it does

Everything you need. Nothing you don't.

Know when they're test ready.

All 27 skills of the DVSA's driver's record, in its 8 groups, marked at the same five levels: Introduced, Helped, Prompted, Independent and Reflection. Your pupils see the same words on Ready to Pass.

Peak ADI turns them into a readiness score out of 5. Always calculated, never typed in. So when you say "not ready to book yet", you've got the evidence.

  • "Test ready" means every skill that counts is at Independent or Reflection, with a mock test pass in the last 60 days. Motorways, driving in the dark, weather conditions, and passengers and loads are tracked, but don't hold a pupil back.
  • A quick check-in after each lesson, with skills suggested from its focus. Your note goes into the pupil's log.
  • Mock tests with driving, serious and dangerous faults. Pass or fail, instantly.
  • See what's moved up this week. Share a friendly progress summary with your pupil.

                  Your day

                  The calm way to run your diary.

                  Day and week views, with your working hours shaded. Weekly repeats, mock tests and practical tests, all in one diary.

                  Drag to move

                  Press, hold and drag a lesson to a new time. Clashes are caught. Any move can be undone.

                  Reminders, if you want them

                  A reminder before each lesson, and an evening summary of tomorrow. Both optional.

                  Directions in one tap

                  To any pickup or test centre, in Apple Maps or Google Maps.

                  Drive times, if you turn them on

                  Between today's lessons, see the drive to the next pickup, with expected traffic from Apple Maps, and whether it fits the gap. Off by default. When it's on, only today's pickup postcodes and leaving times go to Apple Maps. Never pupils' names.

                  Since 12 May 2026

                  Your pupils book their tests now. Peak ADI keeps the record.

                  Only learners can book and manage practical tests now, so it's easy to lose track of who's going when. When a pupil tells you their date, add it to the diary as a driving test. Their page counts down to it, and Today reminds you as it gets close.

                  Peak ADI doesn't connect to DVSA. You add the date. Peak ADI does the remembering.

                  Straight answers

                  Questions instructors ask.

                  Is there an Android version?

                  Sorry, iPhone only for now. Leave your email below, tick "I use Android", and we'll tell you if that changes. There's no iPad-optimised layout, and no web or desktop version.

                  Is there an app for my pupils?

                  Not yet, and there's no online booking. You can share a friendly progress summary with a pupil in one tap. If you need a pupil app, some other instructor apps have one, and one of those will suit you better.

                  What if I lose my phone?

                  Back up to iCloud Drive in one tap (More, then Backup and export), then restore on your new phone. A backup is a file you save, not a live copy, so make one every so often. Automatic iCloud sync is on the way.

                  Where is my data stored?

                  On your iPhone. Peak ADI doesn't have a server, so your pupils' details never reach us. You can lock the app with Face ID or your passcode.

                  Backups go wherever you choose, such as iCloud Drive or Files. Peak ADI doesn't sync between devices yet.

                  Is it Making Tax Digital software?

                  No. Peak ADI isn't MTD filing software, and it doesn't submit anything to HMRC. It keeps your records straight, so whatever software you use has clean numbers: every payment in a UK tax year, in one spreadsheet, for your Self Assessment or your accountant.

                  Can pupils pay by card through Peak ADI?

                  No. Peak ADI records payments. It doesn't process them. Pupils pay you however they do now, and you mark it as cash, bank transfer or card.

                  I've got lots of pupils in another app.

                  Adding a pupil takes about 20 seconds, and the free plan lets you try Peak ADI with three before you commit.

                  Does it sync with my calendar?

                  No. Peak ADI has its own diary, and it works with no signal.
