1. I would have rated 5 stars but didn't do so because- THE MOST IMPORTANT THING- the PERIODIC TABLE is in the worst condition!! which is why it became much difficult to study the VALENCIES.Also I expected to see the valencies of ACID RADICALS in a TABULAR FORM😩.
2. Says token failed, network error all the time when I try to login or sign up.What is the login for!!! You want to create database for emails spamming! I will uninstall it, don't need another spamming app.Not a offline app, useless app.
3. Don't download, I repeat do not download this useless app that wasted my 39mbIt is very good app .Its very helpful for clearing basic concepts.
4. The periodic table is haywire, and I can bet that it hasn't been updated according to IUPAC since at least 2010.
5. Periodic table given is in worst condition.
6. So it's my advice to everyone to download this app and get known to interesting facts about chemistrySeems like app no longer works.
7. I have never seen before any app too bad like thisThis app is useless, it keeps saying network error.
8. I would suggest that yoy rather use GOOGLEIt's a very interesting app for all chemistry learners or beginners.
9. Just a wastage of time and data.Worst app that I have ever encountered.
10. I therefore, hope that the APP DEVELOPER shall show a kind glance and respond to my only request.
11. I am also studying very interesting things about chemistry.
