This app has been updated by Apple to use the latest Apple signing certificate.* Two new modules were added to calculate partial neutralization of an acid solution (from one concentration to a lower one) and to provides an estimation of the pH of the acid solution as a function of its concentration (and vice versa).* In this version, we added the ability to synchronize the records across multiple devices sharing the same iCloud account.* Many bug fixes and functionality improvement including:- User can copy to clipboard the output of the calculation by simply double tapping the output grey box.- Now the selected preferred units will not change when loading a previously stored case.- User can always call back his preferred units by tapping the favorite button in the top menu. - User can also share results through emails or as a screen-capture.- Updated a calculation error in "Solution Preparation" module when selecting "lit" as unit volume
