Honestly, when I first downloaded PeriodicTable, I was just expecting a bland table just saying what elements are on there, without even a description.
However, I was very wrong, as PeriodicTable is packed full of useful information, and even som hypothetical ones, with estimations that are genuine. It shows you all about its structure, its formation of particles and a very precise atomic weight, among a ton of other things.
You don't even need the pro version to get all the basic information (which isn't even "basic" as it already informative) but it sms like it would still help more.
The layout of PeriodicTable is also nice and easy to navigate through, and I am surprised this is not advertised at all. This would be a very good app for students learning the complex world of Chemistry.
Keep up the amazing work!
