Well designed, but...

A few bug fixes should be done and a few extra resources for the price tag. Crashing quite often.

Don't purchase this app

Very disappointed on how limited the information is in this app. Their preview video made me think there was going to be a great deal of useful in-depth content for each icon they offer. Instead it was just the bare minimum amount of information for almost all of them.

It looks like they Googled each topic that they wanted to cover and then basically copied and pasted that information into their app. I don't see where they added value to the basic information that is available to everyone who has access to the internet.

The one section that they did an okay job on was the ColReg icon. It would be much more useful with some basic visuals being added to help demonstrate the major points they were trying to explain.

Overall, don't waste your money on this very basic, limited information and not very helpful app.
