Doesn't work ### 5/5 — Works perfectly on iPhone 5s *2014-09-03, version 3.0.1* Awesome, easy to use app. By far better than the other five lab calculator iPhone apps I tried. ### 1/5 — Hasn't worked in a long time *2014-06-23, version 3.0.1* Can we get a fix for this? Hasn't worked in forever. Just loads to a black screen. ### 3/5 — Does the job *2012-03-22, version 1.7* But it would be nice to have more formulas and useful stuff ### 4/5 — Molto buona *2011-04-28, version 1.7* Molto buona anche se ho notato che talvolta il sistema mette 1.000 sia per quando si intende mille sia per quando si intende uno virgola 000. Sta cosa potrebbe far sbagliare i conti quindi bisogna fare attenzione e controllare per bene. ### 1/5 — Glitchy *2010-08-22, version 0* Had to download 3 times, and still doesn't always open right on iPad. Opens then immediately closes out. Afraid to buy the full version bc of it. Probably won't. ### 2/5 — Peccato *2010-08-01, version 0* Dopo l'ultimo aggiornamento non funziona più, si blocca...peccato, era un'apposita carina e utile. ### 4/5 — Very useful app *2010-06-17, version 0* As a postdoc researcher who carries out molarity calculations on a daily basis this app saves a great deal of time and provides reassurance that you are not making dilution mistakes which can ruin experiments. A notebook to write down and store recepies for physiological solutions such as ringers solution would be useful too especially if it could integrate with the molarity calculator ### 5/5 — Very useful and it's FREE!! *2010-05-20, version 0* What more do you want? ## Frequently asked questions about LabCal ### What does the Laboratory Calculator app do?
