Online Labs Customer Insights

1. I got this only for the simulation purpose trust it has the best simulation good graphics of tools and all.... But when we try to drag any thing in it the whole interface is moving we can do nothing ... Its like you have made a excellent thing and its of no use.... It is very simple like so many apps doing making the simulation full screen and we can interact with the tool easiliy .**c* piece of s**t.

2. This is not mobile friendly at all because while we move any required item during the performance of any practical experiment through simulator, the whole screen moves causing inconvenience.Some Simulations are not working and While opening animation its requiring login option everytime.

3. If in viva option there will be point or grade system than it will be very interesting for students.One of the worst apps that I had seen and whenever I try do an experiment the screen rolls away the table is not working properly This app is the worst while doing.

4. Whenever we try to drag some item the screen keeps on moving, making it impossible to do the experiment.Can't connect circuit in physics as we try to connect circuit screen scrolls.

5. experiments in physics and chemistry I don't want this app anymore and don't want to do experiments in it .Many times it needs to login And it's good I am not complaining for this app It's absolutely fine for students to learn how to perform an activity or practical.

6. It's my positive review One improvement review is that some more video or practical for which I was looking for I didn't get in physics of cardboard and coin one for class 9.

7. While using the simulator, moving objects and scrolling act simultaneously which makes it harder to shift the objects to their intended positions.

8. Its worth 7 star rating but due to this silly thing negetive ..Really appreciate the effort; something like this aids practical oriented education.

9. Don't download if you want to do physics experiment.Very irresponsive app... the app looks awful and is very difficult to operate.

10. However, the developers should fix a minor problem with the interface: scrolling should be automatically locked while using the simulator.

11. Ya, it creates problem when it comes to be used with touch screen devices and that what lost my 1 point(out of 5).
