Getting started
- Point the camera at the problem and tap the shutter — printed or handwritten both work. You can also pick a photo, or type the problem in yourself.
- Two AI models solve it at the same time. Watch both finish on the processing screen.
- The Compare tab shows both solutions side by side. Switch tabs to read one model in full.
- Tap play to hear the steps read aloud, or ask a follow-up question about any step.
The two answers disagree — which one is right?
A disagreement is useful information: it usually means the problem is ambiguous, the photo lost a symbol, or one model slipped. The App highlights the step where the two solutions diverge. Tap Ask a third model to break the tie to get an independent verdict, and check that step yourself. Disagreements are exactly the moments worth learning from.
The problem was recognised wrongly
Fill the frame with just the problem, avoid shadows and glare, and keep the page flat. Exponents and fractions are the first things lost in a blurry shot. If recognition is still off, type the problem instead — typed input skips recognition entirely.
Free limit, Pro, and restoring a purchase
The free tier solves a limited number of problems per day. TwinSolve Pro removes the limit and unlocks the third model and all voice languages. If you already paid — on this device or another one signed in to the same Apple Account — open the paywall and tap Restore.
To cancel a subscription: Settings › your name › Subscriptions › TwinSolve. Deleting the App does not cancel it. Refunds are handled by Apple at reportaproblem.apple.com.
Voice explanations
The explanation language is chosen separately from the App's own language, so you can read the interface in one language and listen in another. If nothing plays, check that the device is not in silent mode and that a voice for that language is installed in Settings › Accessibility › Spoken Content › Voices.
Privacy in one line
No account, history stays on your iPhone, and your picture is sent only to solve that one problem. Full detail in the Privacy Policy and Terms of Use.
