It's OK... I immediately went for the Pro version, but it's a bit underwhelming, particularly in terms of consistency. Terms are not in alphabetical order, some properties such as year of discovery are available in the table, but not in the list. Why? The converse also happens: thermal conductivity is available in list form, not in the table. Finally, as of today selecting density in list form crashes the app. I hope to see some improvements in the future, there is certainly room for growth!

I clicked on an unlabeled icon. It brought up an ad. No big deal, I thought, I'm using the ad supported version. I closed the ad. It immediately brought up a screen with a malware ad that tried to tell me that my device had been hacked. That's BS! It's also quite poor control of the app's ad partners. The app was downloaded from the Google Play Store.

Hello! Let's go through everything point by point:
1: You'll see this message for two reasons: you downloaded the app from a source other than Google Play, or you have root access.
2: The app doesn't contain any advertising banners, static or video banners.
If you see any ads in the app, download it from Google Play.

I had a problem after an update and my license got deactivated. I solved the problem by going to the payments history in my profile and download the pro version from there. I've panicked at first and it is weird that an update uninstalled the pro version and installed the free one (they are different apps)

Hi! I apologize for this situation. Licenses don't disappear; sometimes there are glitches with purchase synchronization. Nobody robbed you. Please forward your request to nks199731@gmail.com, and I will quickly help restore your access!
