Not worth it ### 1/5 — Usless *2014-07-02* This app will not give the resultant products. It is not intuitive to use and there is no instructions on how to use it. Once I figured out how to input the elements for an equation with three reactants, the app would not give me the results. Dom't waste your money on this one. ### 1/5 — Horrible.!! *2013-12-03* It's confusing in every way.!!! Mine always starts on the right of the arrow.! They need to fix this.!!! ### 1/5 — Worst 2$ I ever spent *2012-10-19* Don't buy this!!! It's doesn't work , the only reason y I got it is to balance the equation and it doesn't do it! ### 1/5 — What crap *2012-07-21* Is not intuitive in the least and does seem to be missing any sort of directions on how molecules should be input!! Horrid ### 1/5 — Doesn't work *2012-05-01* There is no calculate icon so it is worthless don't buy it ### 1/5 — Rubbish *2012-04-06, version 1.1* App doesn't work as it only allows equations to be manually inputed. Only equations listed give full App functionality. Support website doesn't work either. Don't waste your money or time with this one. ### 1/5 — Faulty install *2012-02-05* I bought this app only to find the mode selector icons are not there in order calculate! I uninstalled it and reinstalled but it didn't fix the problem... Is there an update that will correct this issue??? ### 1/5 — Wow *2011-12-06* I payed 2 bucks for this expecting it to help balance and it doesn't. Don't buy it ### 1/5 — What a rip off! *2011-11-12* I DL this Ap and could not use it because it was missing some important icons!! Waste of money- thanks alot!! ## Most praised reviews (10 highest-rated) ### 5/5 — Nice app! *2012-03-01, version 1.1* The way to input chemical equation is intuitive. I like the periodic table and the chemical calculator! ### 5/5 — This app helped me a lot! *2011-11-18* The calculator feature is really convenient which made it easy to me to do my work! And it a good tool to store my equations, too. I know this app is for iOS4, but it would be great if I can backup my equations in iCloud:) ### 5/5 — Works Great! *2011-11-07* Definitely worth the money, saves me hours of time on Chem homework when I can just input and press done to balance my equations. ### 5/5 — Great app! *2011-05-03* This is really an amazing app! Looking forward an such app for a long time! Very easy to use! ### 5/5 — great *2011-03-22* MAthenaX great ### 5/5 — Great app!! *2011-03-20* The periodic table input is very cool. There is a small learning curve but it is unavoidable so can't take away any stars. ### 5/5 — Your searching is finish *2011-03-16* I am looking for this app for a long time and the waiting is finished. Amazing app with all you can get in chemical fomulars. Thanks ### 5/5 — Amazing App! *2011-03-15* This is an incredible app that provides handful features to write/record/balance the chemical equation! The most part I enjoy is the chemical keyboard - it makes it so easy to input the elements and I won't worry about forgetting the element name any more! Also, the experience of editing field is very useful. I can easily add or remove new equation items within few simple taps. Great job! ### 4/5 — Chemical equation balance saves time *2021-12-09, version 1.7.7* Pop in your reactants & products & the stoichiometric values are calculated quickly & a screen save allows you to paste the reaction into your text. An significant improvement would be to add the heat of formation. ### 4/5 — great app *2015-03-03, version 1.7.6* Very useful if you know the formulas you are looking to balance. Would be better if it could automatically recognise formulas and potentially auto complete them (maybe that's just me being lazy though). --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
