$54.99 once. Not $139 for 30 days. Not a 90-day pass that expires if your test date slips. Adaptus gives you 4,800+ NCLEX-RN questions with rationales, NGN case studies, and an adaptive engine that predicts whether you'll pass — for one payment, forever. WHY ADAPTUS • 4,800+ NCLEX-style questions with clear rationales across every major nursing domain — med-surg, pharmacology, maternity, pediatrics, mental health, fundamentals, management of care, and more. • An adaptive engine that estimates your ability from every answer and steers you toward the questions that will move your score. • A readiness gauge that forecasts your likelihood of passing as you study — no more guessing whether you've done enough. • Next Generation NCLEX (NGN) practice: six-phase case studies and the newer item formats you'll see on today's exam. STUDY THE WAY THAT WORKS FOR YOU • Daily Drill — a fresh, quick set every day to keep your streak alive. • Boot Camp — longer, focused sessions when you want to grind a domain. • 3,500+ flashcards with spaced repetition — lock in the facts that keep slipping. • Weak-area review — the app tracks what you miss and lets you drill exactly that. SEE YOUR PROGRESS • Topic-by-topic mastery so you know precisely where you stand. • Session history and streaks to keep you honest and motivated. • Every question explains itself, so you learn from misses instead of just scoring them. PAY ONCE — NO SUBSCRIPTION Try it free, then unlock everything with a single lifetime purchase. Cheaper than one month of the big Q-banks, and it never expires. Test date slips? Retake? You still have access. Built for the exam that decides your license. Put in the reps, watch the readiness gauge climb, and walk into test day knowing where you stand. — NCLEX® and NCLEX-RN® are registered trademarks of the National Council of State Boards of Nursing, Inc.

Verdict
The clearest difference is update cadence: Adaptus at every 5 days against Chaipang Subtraction's every 3 months. Chaipang Subtraction's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
