CALL FOR A SCHEDULE CHANGE WHEN YOU HAVE THE CHANCE! IM SAVING YOU FROM THIS PIT OF MISERY. From, an honors chemistry student ### 1/5 — Not the best class for Ms. Pierre-Louis’s class *2018-12-04, version 4.1* Hey, class of 2022 and all future classes. Today is the day you download the absolute worst educational app of all time. Possibly the worst app ever. Anyways, Ms. Pierre will make you download this app anyways. You will find yourself opening the app to a extremely atrocious interface that brings someone back to the days of IOS 6. Also, this does no help your formulas whatsoever. Everyone in my class got a 3/9 or less, which is approximately 33.3%. And trust me we have some pretty smart people in our class. 33% is lower than Cleveland’s NFL record (hopefully), which is super sad. They say the class of 2022 is the worst thing to happen to TFA, I believed that until I downloaded this app. Please, delete the app after being forced to get it. ### 1/5 — Do not download *2017-05-24, version 4.1* None of the apps features are included in the free version. This app is meant as a advertisement for the paid version. Don't waste your time by downloading this app! ### 1/5 — Poor formatting *2017-01-22, version 4.1* Working on an iPad. Unable to choose formulas because of poor formatting. It was completely unusable. Disappointed ### 3/5 — Solution for formula not displayed *2016-09-21, version 4.0* When practicing any category "name to formula" and answer is incorrect & you want to see solution it does not display the formula just the name. Please fix this problem. Thank you ### 1/5 — False advertisement... *2016-09-06, version 4.0* They say it's a free app when in reality you can only access one category. The rest can only be accessed with a purchase. The title for this app should be "_ lite" bc it is not even worth the time downloading when it's practically useless. It's a shame cause it looked promising. ### 2/5 — Not very useful *2014-12-09, version 3.0* The two categories included in the free version are: polyatomic ions and organic functional groups. Neither of these are useful for my students. The scroll through wheel to select symbols and numbers is not a great learning tool in my opinion. ### 5/5 — Amazing app *2014-08-29, version 3.0* Cool app, I really like it ### 5/5 — Great *2014-08-29, version 3.0* Really cool app. I like it. Advice to all ### 1/5 — Other apps are better *2014-08-29, version 3.0* Not a very helpful app ## Frequently asked questions about Chemistry Formula Practice Free ### What learning categories does Chemistry Formula Practice Free cover?
