Very good application
Fantastic. It’s useful to IGCSE students and teachers! (The only problem is you can’t fasten the block by the jaws on the caliper. That’s why I didn’t give it 5-stars. )
Doesn't work. I always get an incorrect answer even on 0
Never shows a correct answer when setting a value. Even setting 0 on the main and 0 on the vernier you get incorrect answer.
