The app allows to discover chemical reactions and to solve the chemical equations with one and or unknown variables. You'll always have Mendeleev's Periodic Table and Solubility table handy. And even the calculator of molar masses!

The app discovers the equations of chemical reactions even if the right or left part is unknown, helps you with organic and inorganic chemistry. The discovered reactions in an usual and ionic aspect will be mapped and formulas of organic chemistry are drawn for you.

Convenient interactive Periodic Table. Tap a chemical element in the table to look the information.

The calculator of molar masses. Enter correctly a chemical compound and it will show molar masses and percentage of elements.

The table of solubility of substances is added in the app as well as Acid strength chart. Now your textbooks become waste!

The best solver of chemical equations for iPhone and iPad.

All these tables and charts are available in the app for free:
* Periodic table
* Chemical reactions search
* Solubility table
* Molar mass calculator
* Electronegativity of elements
* Molecular weights of organic substances
* Reactivity series
* Acid strengths chart

What’s New

Version 5.26

* Design of Molar Mass calculator has improved
* Reactions search screen design has improved for iPad

Works very well

Everything the app describes, but I would like a few simple things to make it a bit more convenient
Tapping to see skeletal structures of compounds on the reactions page
A Wikipedia link to compounds on the reactions page
Setting to detail or to simplify the periodic table (adding orbital types)
Some more detail on the compounds of the reactions page (aq,l,g)
These additions would make it much more useful everyday to me, but still 5 stars easily.

You didn’t think about the blind people!

Please label all buttons, do you do it accessible with voiceover, for blinds people. Label all buttons with normal text please. Especially the second tab with chemicals Alamance is not accessable. Voiceover says, button, button, button, instead of button names.

Developer Response ,


I’ve updated the app by adding the feature you requested. The periodic table accessibility has been improved by providing more info about each element for voice over. Instead of adding bigger fonts I have added zoom to the periodic table so that people who prefer using bigger fonts can scale the table and see all the information.
Please let me know how it works for you. Maybe you can suggest other improvements in this area too?

Best regards,

Quality app

A wonderful app that I am very grateful for, especially its being free! Thank you very much. My only complaint is that I wish the chemical equation/reaction calculator could solve more complex queries. But perhaps this will improve in the future.
