Stimy review
A free mobile math solver that scans work, explains steps, and checks handwritten solutions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Stimy is a mobile math solver for students who want help moving from a problem to an explanation, or checking their own work. Its photo scanning handles printed and handwritten math, and the app returns step-by-step worked solutions with multiple solution methods. Beyond solving, it can assess handwritten answers for accuracy, method, and clarity, generate practice questions, provide topic lessons, and answer follow-up questions through a math chatbot. Official materials cover arithmetic, algebra, calculus, statistics, and probability. Support for 40+ languages makes it a fit for multilingual study, though access is limited to iOS and Android.
The learning loop is broader than answer lookup: students can scan a question, examine the reasoning, ask a follow-up, then reinforce a topic with generated practice or lessons. Handwriting checking adds a distinct use for students who have already attempted a solution and want feedback on both the result and the approach. Multiple methods can also help when one explanation does not match a learner's preferred way of working. Stimy is most suited to individual mobile practice and checking; it is less appropriate for someone looking for a desktop or web-based workflow, or a general study app spanning non-math subjects.
Stimy is freemium, with a free offering and optional in-app purchases for Stimy AI+ features. The vendor's official website promotes AI+ and a free trial, while Google Play confirms free availability and in-app purchases. Published materials do not provide subscription prices, so buyers should check the current in-app offer before deciding whether paid features fit their budget. Choose Stimy if photo-based math explanations, handwritten work checking, and multilingual practice are priorities on a phone. Consider an alternative if platform choice beyond iOS and Android is essential or if you need a broader subject scope.
