Iso2Ortho vs GeoGebra Graphing Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Iso2Ortho
This app offers a tool for projecting isometric models to display four orthographic views, automatically updating as you switch between 1st and 3rd angle projections. It also includes an educational game designed to reinforce understanding of orthographic view positioning through challenges and scoring.
- Isometric to orthographic projection tool
- Automatic view updates
- 1st and 3rd angle projection switching
- Educational game for view positioning
- Scoring based on correctness and speed
- Level progression system

This application is divided into two sections, one being a 1st and 3rd angle projection tool and the second a game. This is not a drawing tool i.e. you cannot draw in this app. The projection tool allows you to project isometric models onto a projection tool so that four orthographic views of the model can be shown. Clicking between 1st and 3rd angle changes the orthographic views automatically. The game is based on helping you understand the position of the orthographic views. Correctly answering the questions will allow you to move up a level. Points are allocated for correctness and speed.
