What it is
= Math Solver is a handwriting-first calculus solver that turns written equations into symbolic answers. Users write with a finger or stylus rather than entering equations with a keyboard or LaTeX syntax. Its symbolic engine is powered by SymPy and handles integrals, derivatives, differential equations and other problem types. The product is built for Calc I–III, differential equations and linear algebra; listed problems also include systems of equations, fractions, arithmetic, limits and summations. Free use allows five solves per day and does not require an account. The Unlimited plan costs $19.99 a year and adds unlimited solves and priority processing. The product is available on iOS and the web, but handwriting recognition and solving require an internet connection. Signing in with Apple syncs settings across devices. The privacy policy says handwritten input is converted to text using the OpenAI API and sent to the solver service. Expressions are processed in real time and not retained after a solution is generated. Data transmission uses HTTPS/TLS, and Firebase handles authentication.

The review
= Math Solver is a handwriting-first symbolic calculator for people who would rather write equations than type them. It is best suited to students working through calculus, differential equations, or linear algebra, and its strongest advantage is the combination of handwriting input and broad symbolic coverage. The free tier is useful for occasional work, while frequent users must accept an online-only workflow or pay for unlimited solving.
Overview
Write an expression with a finger or stylus and = Math Solver turns it into a symbolic answer, without requiring a keyboard or LaTeX syntax. That makes setup substantially less fussy for handwritten equations and notation that can be cumbersome to enter as plain text.
The product has a defined academic focus: Calc I–III, differential equations, and linear algebra. It is therefore a more targeted choice for higher-level coursework than a basic arithmetic calculator. The trade-off is connectivity. Recognition and solving both require an internet connection, so it is a poor fit for flights, classrooms with unreliable service, or any workflow that must continue offline.
Key features
Handwriting-first symbolic engine
The solver uses SymPy to process integrals, derivatives, differential equations, and other symbolic problems. Its recognized problem types include definite and indefinite integrals, systems of equations, differential equations with initial conditions, fractions, arithmetic, limits, and summations. That list covers a substantial portion of standard calculus and adjacent coursework, although it should not be treated as an all-purpose mathematics environment.
Accounts, processing, and privacy
Free solving does not require an account. Signing in with Apple can synchronize settings across devices, which is useful for someone moving between an iPhone, iPad, and the web version. Handwritten input is converted to text through the OpenAI API and sent to the solver service; expressions are processed in real time and are not retained after a solution is generated. Transmission uses HTTPS/TLS. Firebase handles authentication, and the service says Firebase maintains SOC 2 compliance. RevenueCat manages subscriptions.
Support
Support is available by email at [email protected], with the maker saying replies typically arrive within 24 hours. That gives paid users a clear route for account or subscription questions.
Pricing
The Free plan costs nothing, is described as billed every day with no strings attached, and includes five solves per day, the full symbolic engine, and handwriting input. Five daily solves are enough for checking selected homework questions or occasional reference work, but they are restrictive for a long study session or repeated experimentation.
Unlimited costs $19.99 a year, billed at $19.99 /year, and adds unlimited solves and priority processing while retaining everything in Free. It can be canceled anytime. The service also presents paid access as starting from $3.99/mo; the annual Unlimited offer is the specifically stated plan and is the more suitable choice for regular users who would otherwise hit the daily cap.
Platforms
= Math Solver is available on iOS and the web. Settings synchronization through Apple sign-in helps keep preferences consistent across devices, but solving itself still depends on an active internet connection.
Who it's for
This is a strong fit for students in Calc I–III, differential equations, or linear algebra who want to write equations naturally and receive symbolic results. It also suits occasional users who can stay within five solves per day and do not want to create an account. It is less appropriate for heavy daily use unless the annual Unlimited plan fits, and it is not the right choice for offline study or users seeking a general solver with no connection requirement.
Pros and cons
Pros
- Handwriting input: Finger or stylus entry avoids keyboard formatting and LaTeX syntax.
- Broad advanced coverage: Integrals, derivatives, differential equations, systems, limits, and summations address core higher-level coursework.
- Usable free tier: Five daily solves and the full symbolic engine require no account.
- Cross-device settings: Apple sign-in can sync settings between devices.
- Clear data protections: HTTPS/TLS transmission and real-time processing without retaining expressions after solution generation.
Cons
- Five-solve daily ceiling: The free plan can run out quickly during homework or revision.
- Internet required: Recognition and solving stop being available without connectivity.
- Limited platform scope: Support is for iOS and web rather than a wider range of native platforms.
- External processing: Handwriting passes through the OpenAI API and authentication and subscriptions involve Firebase and RevenueCat.
Alternatives
Photomath is the alternative to consider for Android and iOS users who want step-by-step explanations, with a free Basic tier and an annual Plus plan at $69.99 a year.
SnapXam is a better direction when API access or step-by-step explanations across algebra, trigonometry, and calculus are priorities.
Ada+Max suits users looking for a broader study package that combines checking work, flashcards, games, and progress tracking.
AI Mathbot is an alternative for users who want a basic solver on Android, iOS, macOS, and the web, with a separate Pro subscription.
AllMath AI Math Solver is a free alternative with a 70,000-credit allowance and a basic model.
Amend is aimed at iOS users who want homework checking rather than a dedicated symbolic handwriting solver.
AskMath is worth considering if monthly access to advanced models and a larger credit allocation matters more than handwriting-first entry.

Verdict
Choose = Math Solver if you are studying calculus or related subjects and want to write equations naturally while getting symbolic results. Its focused subject coverage, no-account free tier, and handwriting workflow are the main reasons to pick it. Look elsewhere if five solves a day is too few, if you need offline operation, or if your platform is outside iOS and the web.
