Certly prepares you for all four AI certification exams: Associate, Developer, Architect and Architect Professional. 415 practice questions, all built from the official exam guides. ▸ Four Exams, One App Pick the certification you're sitting and the whole app follows it: its domains, its weights, its exam length. Switch any time. Your progress is kept separately for each. ▸ Weighted Like the Real Thing Every question is filed under the domain it tests, at the percentage the official guide publishes. Your projected score is weighted the same way the real score report is, so it means something. ▸ Realistic Practice Exams Full-length, at each exam's real item count, scored 100 to 1000 against the same 720 passing line. Both question formats are here. Multiple-choice, and multiple-response items that tell you how many answers to select and grade on an exact match, with no partial credit, exactly as the real exam scores. ▸ Explanations That Teach Every question explains why the right answer is right and why each wrong one is wrong. No lettered cross-references to decode. Explanations name the answers by what they say. ▸ Prompt Lab Hands-on prompt-writing drills graded instantly and offline. Spot the flaw in a weak prompt, build a strong one block by block, or write your own against a precision rubric. ▸ Smart Review with Spaced Repetition Questions you miss come back at widening intervals until they stick. ▸ Study by Domain, or in Ten Minutes Target a single domain, or take ten mixed questions on the way to work. ▸ Daily Challenge, Streaks and Achievements A fresh question every day, accuracy tracked per domain, and milestones as you climb. HOW IT WORKS 1. Choose your certification 2. Study by domain, take a quick session, or run a prompt drill 3. Review the explanation on every answer 4.

Verdict
The clearest difference is in-app purchases: Cashflow Engineers at none against Certly's 1. Cashflow Engineers also leads on device support (3 vs 1) and iOS requirement (15.1 vs 26.2). Certly's advantage is update cadence (every 2 months vs every 5 months). On price and ads there is nothing between them.
