SARON Prep · iPhone, iPad & Mac

Support

A study aid for the ATPL(A) SARON written examination — air law and procedures, aeroplane systems and operation, and general navigation.

Requirements

iPhone or iPad running iOS 26.0 or later, or a Mac running macOS 26.0 or later. Studying works entirely offline; the internet is used only by iCloud, to sync your progress between your devices, and by the App Store for the optional Full Access purchase.

How the app works

Practise by topic with instant feedback, or sit a full 80-question mock exam under the real 3½-hour time limit with the pass mark at 70%. Every answer is tracked: missed questions come back on a spaced schedule in Smart Review, and the Home tab estimates your readiness by section and topic. The Load & Trim Trainer generates a fresh load and trim sheet with questions computed from it — zero fuel weight, per cent MAC and the weight-shift problem — and the Calculation Drills generate ISA, density altitude, fuel, crosswind, convergency, time zone and descent problems with worked solutions.

Progress and resetting

Your iPhone, iPad and Mac combine their progress through your own iCloud account: answers add up, the review schedule carries on from your latest answer, and mock exam results from every device appear together. Sign in to iCloud on each device; the switch is in Library › Sync, and it is on unless you turn it off. Every device still keeps its own copy, so studying works offline and catches up when you are back online. To start over, use "Reset all progress" at the bottom of the Library tab: with sync on it erases progress on every device, with sync off on that device only.

Full Access, restoring a purchase and offer codes

The app is free to try: 50 practice questions in any mode, one full 80-question mock exam, and the whole Library. Full Access is a single one-time in-app purchase — no subscription — that unlocks every question, unlimited mock exams and all the trainers, on your iPhone, iPad and Mac. It follows your Apple Account: on another device it unlocks by itself, or tap Restore purchases in Library › About. Have an offer code? Tap Redeem a code in Library › About or on the purchase screen. With iCloud sync on, the free questions and the free mock exam are shared by your synced devices. Downloaded the app before version 1.3? You keep everything, free.

A question looks wrong?

Every question carries an explanation and a source reference. If you believe an answer conflicts with the current TC AIM, CARs or CAP, email the question text and your reference — verified corrections ship in the next update. Always treat the current official publications as authoritative.
