Why We Tested These Five Math Solver Apps
The "snap a math problem and get the answer" category has gotten crowded. Photomath kicked it off back in 2014. Mathway, Symbolab, and Gauthmath followed with different angles — typed input, deeper symbolic steps, live human tutors. And in 2024–2026, a wave of AI-first apps (including Solver AI) rebuilt the experience around modern multimodal models that can read, reason, and explain.
If you're a student staring at the App Store right now wondering which one to actually download, every blog ranks them differently — and most of those rankings exist to push affiliate links. This one doesn't. We tested all five across the same set of homework problems and graded what they're actually good at.
OCR accuracy — how often the app correctly reads a photo of a handwritten or printed problem.
Step quality — are the steps actually explained, or just listed as algebra?
Topic coverage — algebra only, or all the way through calculus and statistics?
Free tier — what do you get without paying?
Honesty — does it gate the actual answer behind a paywall, or only the deeper explanations?
The five apps we tested
We picked the apps with the largest active install base in 2026: Photomath (now owned by Google), Mathway (Chegg), Symbolab (Course Hero), Gauthmath (ByteDance), and Solver AI. We left out toy apps, single-topic calculators, and apps that are obvious GPT wrappers without OCR. Pricing checks were done in June 2026 — promo rates change, so verify in the App Store before subscribing to any of them.
At a Glance — The Comparison Table
Before the deep-dives, here's where each app lands across the dimensions that matter most for students. Skip ahead to the section for any app you're already considering.
| App | Photo OCR | Free Tier | Step Quality | Topic Coverage | Best For |
|---|---|---|---|---|---|
| Photomath | Excellent | Basic steps free | Animated, polished | K-12 → Calc 1 | Clean printed equations |
| Mathway | Good | Answer free, steps paid | Brief, formal | Algebra → Stats + sciences | Typed input, wide STEM range |
| Symbolab | OK | Limited steps free | Deepest, most rigorous | Algebra → Diff Eq | Showing every line of work |
| Gauthmath | Good | Few free questions/day | Tutor-written | K-12 mostly | Word problems & geometry proofs |
| Solver AI | Excellent (AI-based) | Free to try | Conversational, modern | Algebra → Calc, Geo, Trig, Stats | Modern AI-first alternative |
If you're scanning printed textbook problems, Photomath still has the cleanest OCR. If you want the deepest worked steps for algebra or calculus, Symbolab. If you want a modern AI-first solver that handles photos, typed equations, and word problems in one place, Solver AI. The other two are situational picks.
Photomath — The OCR Pioneer
Photomath was the first app to nail "take a picture of math and get the answer." Google acquired the company in 2022, and the app is still actively maintained — though the pace of feature shipping has slowed compared to the early years.
What it does well
The OCR engine is still the gold standard for printed textbook problems and clean handwriting. Animated step-by-step explanations are the most polished in the category — they walk through each transformation with text annotations rather than just listing the algebra in a column. For a middle or high school student working through a textbook, that polish matters.
Algebra 1 and 2 problems from a textbook page. Linear equations, factoring quadratics, simplifying expressions — Photomath nails the scan and gives you a smooth, animated walkthrough that's friendly enough for younger students.
Where it falls short
Word problems remain a weak spot — Photomath is fundamentally an equation-recognition engine, not a problem-comprehension engine. You usually need to extract the equation yourself before scanning. Coverage of higher-level calculus topics (series, multivariable, differential equations) is thinner than Symbolab. And the most useful step-by-step depth is gated behind the paid Plus tier.
The free tier gives you the answer and basic steps. The detailed "why this step" explanations and the more advanced topics require Photomath Plus. Check current pricing in the App Store before subscribing — Plus pricing changes frequently with promos.
Best for: Middle and high school students working through algebra textbook problems with clean printed equations. Skip if: you do a lot of word problems, or you're in college-level calculus.
Mathway — The Topic-Breadth Champion
Mathway is the textbook-input cousin of Photomath. It started life as a website back in 2002, got acquired by Chegg in 2020, and remains popular thanks to its very wide topic coverage and fast typed-input experience.
What it does well
Topic breadth. Mathway covers basic math, pre-algebra, algebra, trigonometry, precalculus, calculus, statistics, finite math, linear algebra, chemistry, and physics — broader than any other app in this lineup. The symbolic keyboard for typed input is fast and well-designed; punching an equation in is often quicker than aiming a camera.
Where it falls short
The free tier shows you the final answer but gates step-by-step explanations behind a Premium subscription. That's a real friction point if you're using the app to learn rather than just check answers — and learning is the whole point. The OCR works but isn't as clean as Photomath. And the step explanations themselves are brief and formal — less hand-holding than Photomath's animations.
Mathway's paywall pushes harder toward Premium than Photomath's. If you only want to verify a final answer, the free tier is fine. If you actually want to learn the steps, the paywall hits fast.
Best for: Students who prefer typing problems and want one app that covers chemistry and physics alongside math. Skip if: you mostly want to scan, or you want step-by-step explanations without paying.
Symbolab — The Step-by-Step Algebraist
Symbolab (now owned by Course Hero) is the algebra and calculus heavyweight. It's been the go-to for serious math students since the early 2010s because of one thing: the depth of its step-by-step engine. Nothing else in this category shows as many intermediate lines of work.
What it does well
Symbolab shows more intermediate steps than any other app. For a tricky integration by parts or a partial-fraction decomposition, Symbolab will walk through the substitution, the chain rule expansion, and the simplification — line by line — exactly the way a TA would write it on the board. It also has dedicated calculators for almost every standard problem type: limits, derivatives, integrals, series convergence, matrix operations, ODEs.
AP Calc BC, college Calc 1–3, linear algebra, differential equations. If the problem has a symbolic answer, Symbolab will derive it and show every line of work — perfect when your professor wants the full derivation, not just the final answer.
Where it falls short
The OCR is the weakest of the five — for photo input, you're often better off retyping. Word problems are not its specialty. The interface feels dated compared to Photomath and the modern AI-first apps. And the most useful step-by-step detail is gated behind a Pro subscription that's pricier than most competitors.
Best for: College students or advanced high schoolers who need rigorous, complete worked solutions and don't mind typing the problem in. Skip if: you want a fast snap-and-solve experience, or you're working below Algebra 2.
Gauthmath — AI Plus Live Human Tutors
Gauthmath is the hybrid: AI for instant answers, live human tutors for harder problems. Owned by ByteDance (TikTok's parent), the app is positioned squarely at K-12 students and has grown fast since 2020.
What it does well
The human-tutor backstop is genuinely useful for word problems and geometry proofs — areas where pure AI engines still occasionally trip up. The free tier is more generous than Mathway or Symbolab for asking real questions (within a daily limit). The UI is polished and student-friendly, and the in-app community features make it feel less transactional than the older apps.
Geometry proofs and tricky word problems. The tutor explanations are written by people, so they read more like a tutor's note than a machine's output — which makes them easier to follow when you're stuck on a concept rather than an equation.
Where it falls short
Calculus and higher math coverage is thinner than Symbolab — Gauthmath's sweet spot is middle and high school. Tutor turnaround time is fast but not instant. And the credit/ticket system means heavy users hit a soft paywall quickly.
Best for: Middle and early high school students, especially anyone struggling with word problems and proof-style geometry. Skip if: you're in college-level calculus, or you want instant AI responses on every question without queuing for a tutor.
Solver AI — The Modern AI-First Solver
Solver AI is the newest app in this lineup — built from the ground up around modern multimodal AI models rather than the legacy OCR-then-symbolic-engine pipeline that the older apps still rely on. Available on iOS.
What it does well
The AI-first design means it doesn't matter much whether your input is a photo of a printed problem, a typed equation, or a screenshot of a word problem — Solver AI parses the intent and walks you through the solution in plain language. Because it uses a modern multimodal model, it handles word problems, mixed-media questions, and multi-step prompts that trip up the legacy OCR-only apps.
Mixed-input homework sessions — some scanned, some typed, some word problems — without app-switching. Algebra, calculus, geometry, trigonometry, and statistics all covered with conversational step-by-step explanations that feel like a tutor walking you through the problem rather than a computer dumping symbols.
Where it's still growing
Brand recognition. Solver AI hasn't been around as long as Photomath or Mathway, so you won't find it on a "top 10" list from five years ago. It's only available on iOS. A few highly specialized features in the established apps (like Symbolab's differential-equations module or Gauthmath's live human-tutor backstop) aren't there yet.
The legacy math solver apps were designed for an era before large language models could read and reason about problems. Solver AI rebuilds the experience from scratch with a modern model at the core — so a single app handles scan-and-solve, typed equations, and conversational word problems without the rough handoffs you can feel in older apps.
Best for: Students who want a modern alternative to Photomath that handles word problems as cleanly as it handles equations, with explanations that read like a tutor's. Try Solver AI free on the App Store to see how AI-first math solving compares to the old guard.
How to Pick the Right Math Solver App
There's no single "best" math solver app — the right one depends on what you're solving, how you want to interact, and how much you're willing to pay for the deeper steps. Here's the decision tree that fell out of our testing.
- If you mostly scan printed textbook problems
Photomath — best OCR, polished animations, friendly for younger students. Solver AI is the closest modern alternative with comparable scan quality.
- If you want a single app for math + physics + chemistry
Mathway — widest topic coverage across STEM subjects. Just expect to pay for steps.
- If you want the deepest worked steps for calc or higher
Symbolab — nothing else shows as many intermediate steps for symbolic math. Best for serious college calculus and beyond.
- If word problems and geometry proofs are your pain
Gauthmath (for the human-tutor backstop) or Solver AI (for the modern AI parsing of natural-language problems).
- If you want a modern AI-first experience
Solver AI — built around current multimodal AI rather than legacy OCR pipelines. Best fit if you've outgrown how Photomath handles word problems.
Frequently asked questions
Yes — Photomath shows basic steps free, and Solver AI is free to try with step-by-step solutions. Mathway and Symbolab gate detailed step-by-step explanations behind subscriptions, though both let you see the final answer for free.
For scanning clean printed equations, Photomath's OCR is still the most reliable. But modern AI-first apps like Solver AI now match or beat it on word problems and conversational explanations, and Symbolab still leads on raw step-by-step depth for calculus. "Best" depends on what you're solving.
Symbolab for raw step-by-step depth on Calc 1–3, linear algebra, and differential equations. Solver AI for a faster, conversational experience that handles word problems and applied math more naturally. Many college students keep both installed.
No — phones aren't allowed on the digital SAT. But the digital test has a built-in Desmos calculator, and apps like these are great for SAT prep at home in the weeks leading up to test day.
The math solver category isn't winner-takes-all anymore. Photomath still owns clean OCR, Symbolab owns step depth, Mathway owns topic breadth, Gauthmath owns the human-tutor angle, and the AI-first generation (Solver AI) is the most natural fit for word problems and conversational learning. Try the one that matches the work you actually do — and don't be afraid to keep two installed for different jobs.
