I used this ap last year and it was great- now it doesn't let you type in the number of subatomic particles to add, so you can't do anything! Please fix this! I've tried re-installing it, but it didn't help.
Help me a lot!!!!!
I was having problems using the real deal till this came into the App Store. I'm in the eighth grade and it still helped me!!!!!!!!!
Gives you no way to add electrons proton or neutrons. Screen says "Drop to Add" but there's nothing to drop anywhere. There are no instructions on how to use this app which is why the title is Worthless! What a complete waste of time. Deserves negative stars
With Family Sharing set up, up to six family members can use this app.
