Pocket Prep is a popular, cheap mobile question-bank app — bite-sized quizzes, mock exams, and analytics across hundreds of exams (including the CCMA, CET, and CPT). Trelos is a mobile retention engine that teaches each concept, drills it, and schedules spaced review. Both are affordable and mobile-first — the difference is that Pocket Prep reinforces, while Trelos teaches and retains.
Pocket Prep has been a go-to mobile study app since 2011, and it's the largest provider of app-based practice questions for professional certifications — covering hundreds of exams across medical, financial, fitness, IT, and behavioral health, including NHA allied health exams like the CCMA, CET, and CPT. Its strength is convenient, bite-sized drilling: expert-written questions with detailed explanations and textbook references, mock exams, and study modes like Question of the Day, Quick 10, Build Your Own Quiz, Missed Question Quiz, and Level Up, plus performance analytics and peer comparison. It's cheap — roughly $16–$21 per month or about $96–$125 per year depending on the bundle — with a free tier and a pass guarantee. It's genuinely handy for squeezing in practice on a phone. The key thing to understand is what it's for: it's a question bank designed to reinforce and self-assess material you learn elsewhere, which is why many users pair it with a textbook.
Trelos is also mobile-first and affordable, but it's a complete prep engine rather than a question bank. Instead of only quizzing you, it teaches each concept, drills it with exam-style questions, and then schedules your reviews using spaced repetition — resurfacing each concept right as you're about to forget it. It adds hypercorrection (re-teaching confident wrong answers immediately) and interleaving (mixing topics) on top. The aim is to take you from not knowing the material to durable, exam-ready recall — built around each exam's specific blueprint — without needing a separate textbook or course alongside it. Tracks: HESI A2 180 questions across 30 concepts, TEAS 180 across 30, CCMA 180 across 30, CPT 168 across 28, CET 180 across 30, all standard multiple choice with an explanation on every answer.

Choose Pocket Prep if you've already learned the material (from a course, textbook, or program) and want a cheap, convenient way to drill practice questions on your phone, track weak areas, and take mock exams. Its breadth of exams and low price make it an easy add-on, and the bite-sized format is great for studying in spare minutes.
Choose Trelos if you want one tool that both teaches the content and makes it stick — teaching each concept, drilling it, and automatically resurfacing it so it's retained through test day. For a broad exam like the CCMA, having the learning and the spaced review handled together, rather than drilling questions on top of a separate textbook, is the core advantage.
Pocket Prep is a genuinely useful, affordable app, and for someone who's already studied and just wants extra question practice, it's an easy recommendation. Its limitation is by design: it's a question bank, not a course, so it reinforces rather than teaches, and its review is centered on missed questions rather than a full spaced-repetition schedule across everything. Trelos is built to be the complete tool — it teaches, drills, and retains in one mobile-first system — which is the better fit if you want to learn the material and lock it in without assembling a textbook plus a question app.
Pass guarantee: learn every concept in your track and keep up your scheduled reviews, and if you still don't pass, your access is extended free — three more months per attempt — until you do. It's an extension, not a refund.
If you’re preparing for the HESI A2, TEAS, or an NHA certification — Trelos has a dedicated track for each: short lessons, exam-style questions with explanations, and spaced review that brings back what you got wrong. Every track’s first topics are free with no sign-up to start. Pick your exam:
