Purpose-built for pilots who refuse to leave their checkride to chance. CheckPrep is a checkride oral prep app for the Private, Instrument, Commercial and Commercial Multi Add-On practical tests, built around the FAA Airman Certification Standards (ACS), the exact framework your DPE uses to evaluate you. This is not written test prep. This is oral prep. STUDY THE WAY YOUR DPE TESTS YOU Every question, answer and reference is organized by ACS Area of Operation and Task, the same structure your examiner follows. Every card maps to an ACS task, so every minute of study maps to your oral exam. THE FAA LIBRARY, FREE FOR EVERY USER Full FAR, AIM, Advisory Circulars, the ACS documents themselves, FAA letters of interpretation, InFOs and the FAA handbooks: PHAK, AFH, Instrument Flying, Instrument Procedures, Aviation Weather, Risk Management, Weight & Balance, Chart Users' Guide and the AMT handbooks. Tap a citation on a study card to open the exact paragraph, page or ACS element. Bookmark passages, search by keyword, read offline after download. AIM paragraphs also open on the FAA website, so you never have to wonder whether it is current. KNOW WHEN YOU'RE READY Mastery is tracked from 0 to 100% for every ACS task. Flash cards and multiple-choice quizzes are built from the same cards. Switch on the Needs Review filter to limit a session to the cards you still miss and leave the mastered ones out. When every task reads 100%, you know where you stand before the examiner does. DECODE REAL-WORLD WEATHER METAR, TAF and PIREP decoding practice with live data from aviationweather.gov. Included free. TRAIN YOUR EAR Departure (CRAFT) and approach (P-TAC) clearance trainers read the clearance aloud. You give the readback by voice. Beta, included with the Instrument guide. BUILT FOR YOUR CERTIFICATE Start with the free Private Pilot Sample: four complete ACS tasks with flash cards, quizzes and tappable citations.

Verdict
The clearest difference is update cadence: CheckPrep at every 3 days against CROSSorCHECK's monthly. CROSSorCHECK's advantage is iOS requirement (15.1 vs 26.2). On price, ads, in-app purchases and device support there is nothing between them.
