Good for Instruments
The only issue that I have is that when it comes to contamination it seems to be that the background is at 0cpm. You cannot also practice calculations such as inverse square law, stay time, etc.
I feel like this app has a fantastic ability to help someone practice their readings, however there is plenty more room for adding new content to practice.
Is it worth the $4.99? Not yet but I hope that more gets added.
I will definitely keep up with my practice in the meantime.
