Comments on Chemical equation keyboard A for Android
★★★★★ho ho· Feb 11, 2020
Almost all chemical reaction formulas learned by high school can be written with this keyboard. You don't need to switch between alphabets, numbers and symbols, so you can write very quickly. Thanks to the development team for a very good job.

Good enough but there are still many limitations
★☆☆☆☆Bhuvana Raghunandan· Dec 28, 2018
Cannot type on the lower or upper bracket and cannot type catalyst on the arrow and if we type inside the bracket the size of the alphabets does not reduce say for example if you want to write gaseous small (g) (in the small bracket it doesn't become. Size of the arrow for writing the catalyst also does not increase it is a fixed size. And use of small letters is very difficult

Very, very bad, amount has been deducted, but app is not installed. Very wrong
★☆☆☆☆romi adhikari· May 7, 2022
I could not even find the app on my screen after installing. Nor I could find it in the keyboard while typing. Absolutely no trace of the app. And I paid for it.
