One purchase. No subscription.
Start free in the app. Unlock everything with a single one-time purchase.
Not a static question dump
Practice that’s generated fresh. Every time.
Memorising one sample answer won’t help when the exam hands you a new document. So the apps build new ones on every run.
Charts, plates and weather maps
INRAT and CPL Prep draw a new fictional chart for every run, then mark the solution on it.
Nav logs and loading sheets
PPL and Private Pilot Prep generate VFR cross-country logs, weight-and-balance, METARs and TAFs.
Computer flight plans
SAMRA, SARON and Dispatch Prep build fresh flight plans and load and trim sheets to compute from.
Spaced review
Missed questions return on a schedule until they stick. The dashboard shows you against the pass mark.
Questions? Straight answers.
Is the web version the full app?
No. PSTAR and ROC-A are complete and free on the web. For the other exams the web shows real sample questions; the full trainers live in the iPhone, iPad and Mac apps.
What does it cost?
PSTAR and ROC-A are free. The apps are free to try, and unlocking everything is a single one-time purchase, not a subscription.
Where is my progress saved?
On the web, in your own browser only. Your answers are never sent to us, and clearing your browser data clears them.
Do I need an account?
No. There are no accounts and no ads.
Are you connected to Transport Canada, the FAA or ISED?
No. This is independent study material. Always check figures against current regulations and official publications.
