iDynamics is an app for teaching and learning purposes. With this app any vibration and shock measurements and system identification analyses (e.g. determination of frequency and damping) can be performed. Furthermore, the app can be used for condition monitoring of the structure "Structural Health Monitoring". Thus, changes in the dynamic properties of the structure (e.g. due to damage) can be detected and evaluated. The application and use of the "iDynamics" app is intended for teaching and learning purposes only. The app will be further developed as necessary for the above-mentioned purposes. Other uses of the app outside of teaching, especially for legally binding and obligatory measurements as well as commercial use are not allowed or excluded.

Verdict
The clearest difference is review sentiment: GeoGebra Graphing Calculator at 54% against iDynamics's 0%. GeoGebra Graphing Calculator also leads on update cadence (monthly vs every 3 months). iDynamics's advantage is iOS requirement (12.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
