Math Vale is a role-playing game where the world runs on mathematics. Every kingdom is a branch of it, every Keeper guarding a gate is a set of real problems, and the only way forward is to understand the idea — there is nothing to grind and nothing to rush. • 141 skills across eleven kingdoms, from counting and fractions to trigonometry, calculus and linear algebra • Lessons that explain, hints that nudge without giving the answer away, and a Journal that keeps every mistake so you can fix it later • Problems that adapt to what you know, and reviews that come back when a skill starts to fade • A homestead to build, quests, dragons and hidden caves of competition problems • Play alongside classmates and family, spar with a friend, or defend a castle together Four kingdoms are free for ever — counting, number sense, fractions and algebra — with no limit on how much you play. The other seven, geometry through calculus and linear algebra, open with a subscription or a one-off unlock, and a free fortnight begins the first time you reach them. Nothing inside the game is ever for sale: no coins, no lives, no hints. Built for children, so it asks for very little: a username, a display name and a password — no email, no phone number, no date of birth. No adverts, no analytics, no tracking. Subscription and purchase terms • Math Vale, a year: an auto-renewing annual subscription that opens every kingdom. • Math Vale, for good: a one-off purchase that opens every kingdom and never renews. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically at the same price unless it is cancelled at least 24 hours before the end of the current year. You can manage or cancel it in your Apple Account settings at any time.

Verdict
The clearest difference is in-app purchases: AR PiaMia at none against Math Vale's 2. AR PiaMia also leads on iOS requirement (9.0 vs 17.0). Math Vale's advantage is update cadence (every 4 days vs every 13 months). On price, ads and device support there is nothing between them.
