Here is a free app for the mobile learning tool Tec2Screen® from Festo Didactic. The app offers the following functions: within a course, you can learn more about how Tec2Screen® is structured and works in practice. Are you interested in a double-acting cylinder is actuated? No problem, you will find a small model circuit in the app, either with real components or simulated as a circuit with symbols. The integrated software iEasyLab allows you to design digital circuits by virtual means. You select symbols from a library, such as logic components, indicators, and measuring instruments, place them on the iPad and start the simulation. The program then presents the results. In conjunction with the mobile learning tool Tec2Screen® from Festo Didactic, learning and understanding will be better and faster in the future. It's the connects that make it possible: these core elements of connected learning are a seamless link between the virtual world and the real world – unique in the world of basic and further industrial training!
CO2 Modeller
Simulate the impact of reducing carbon emissions on climate change. This app generates projections for atmospheric CO2 concentration, global warming, sea level rise, and ocean acidification.
- Model carbon emission reductions
- Simulate climate change effects
- Project CO2 concentration
- Estimate global warming
- Predict sea level rise
- Analyze ocean acidification

Model the effect of carbon emissions reductions on climate change using your smartphone or tablet. CO2 Modeller uses a streamlined computationally efficient Earth system model to simulate the effect of carbon emissions reductions on climate change. It generates twenty-first century projections of atmospheric carbon dioxide concentration and global averages of surface warming, sea level rise and ocean acidification.

Verdict
The clearest difference is update cadence: Tec2Screen® at every 6 months against CO2 Modeller's every 36 months. Tec2Screen® also leads on iOS requirement (8.0 vs 12.1). CO2 Modeller's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
