Angles Calculator vs Resolve AI
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Angles Calculator
This app helps users understand and calculate angles and lengths in right-angled triangles. It provides step-by-step workings for each calculation, aiding comprehension of trigonometric ratios and triangle properties. It also calculates the triangle's area with explanations.
- Calculates triangle angles and lengths
- Explains trigonometric ratios (sine, cosine, tangent)
- Shows step-by-step workings
- Calculates triangle area with explanation
- User-friendly input via touch diagram
- Clear all function for resetting

Do you need to learn how to determine the angles and lengths of a Right Angle Triangle? Need to clearly understand which of the sine, cosine and tangent ratios to use? Need to know how to determine the angle when you know two of the sides. If the answer is Yes to any of these questions then this App is for you. The Angles Calculator not only calculates the answers for you but it also tells you how it did it so you can understand how and when to apply the rules for right angle triangles. New this version: Now the area of the triangle is calculated for you. An explanation of how this was done is also given. The App is simple to use. Just enter an angle and a side or two sides and all the others will be calculated for you. To see how the answers were arrived at just select the 'Workings' button and a page is shown with a comprehensive set of steps to show how each was calculated. To enter a value for an angle or a side just touch the diagram on or near the one you want to specify. The keypad pops up. Enter the value you want and select OK. Select the other value and do the same. When you press OK this time the App calculates the other values. To start over select 'Clear All'. All values are reset. You can now specify two other values. Note: The App cannot calculate the answers if you specify two angles and no sides. It is mathematically impossible. You have to specify an angle and a side or two sides.

Resolve AI is a study assistant that explains instead of just answering. Photograph a problem or type it in — and get a full walkthrough, the way a patient tutor would write it out on paper. HOW IT WORKS • Snap the task with the camera or paste the text • Get the solution broken into steps, with the reasoning behind each one • Ask follow-up questions right in the chat until it clicks WHAT IT DOES • Geometry drawings — flat figures and 3D solids, built with correct proportions, labels, and cross-sections • Function graphs — plotted from the formula, with intercepts and extrema marked • Physics laid out properly: Given / Find / SI / Solution / Answer • Quizzes on the topic you just studied, so you can check yourself • Code and algorithms — Python, C++, Java: explained line by line, with flowcharts • Languages — grammar, translation, essays, and writing help SUBJECTS Math, algebra, geometry, trigonometry, calculus, physics, chemistry, biology, computer science, English and foreign languages, literature, history, social studies, geography. WHY IT ISN'T A CHEAT SHEET Every solution is worked out from scratch, not pulled from a database of ready answers. You see the path, not just the final line — which is the part that actually shows up on the test. If your input has a mistake in it, the app points at the exact step and explains what went wrong. BUILT FOR PHONES Diagrams and graphs render natively — you can zoom, rotate, and inspect them. Formulas are typeset properly. Your chat history is kept, so you can come back to a solution weeks later. SUBSCRIPTION New users can try Resolve AI for free — depending on the offer shown in the app, with a free trial of the weekly plan or with free solutions. Plans: weekly, monthly and yearly; the price and any trial terms are shown before you confirm. Subscriptions renew automatically at the displayed local price unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple ID settings.

Verdict
The clearest difference is price: Resolve AI at Free against Angles Calculator's $0.99. Resolve AI also leads on update cadence (every 2 weeks vs every 2 months) and review sentiment (100% vs 82%). Angles Calculator's advantage is ratings volume (10 vs 2) and iOS requirement (14.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
