Sta cosa potrebbe far sbagliare i conti quindi bisogna fare attenzione e controllare per bene. ### 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 ### 4/5 — Génial mais... Great but... *2009-06-27, version 0* ... En anglais et français s'il vous plaît! ... In english and frensh please! ### 4/5 — Great free tool *2009-01-24, version 0* Really helpful at the bench. Why calculate molarity manually when you can use a computer. ### 4/5 — Very useful! *2009-01-21, version 0* Actually, having used it more than a few times now in the lab, I would say this is a very useful app. On top, it is free. Solutions app will cost you 2.99 and, judging from the description, does the same job. Suggestion for future update: Would it be possible to save an entry? Currently, the entry is lost upon quitting the app... Also, what about a database of commonly used chemicals (salts, buffers...)? Thanks! ### 4/5 — Really nice App *2008-12-07, version 0* Another reason to have an iphone on the lab bench. Very useful App. ### 4/5 — like the new updates! *2008-10-06, version 0* Being able to choose the output variable is very helpful. Yes, these calculations can be done on any calculator, but this is very convenient. I do this sort of calculation frequently in the lab, and this will save time. The sliders for choosing units can be hard to use - the slider seems to jump and has to be reset, sometimes more than once to get it to stay at the chosen point. ### 4/5 — Very good *2008-09-26, version 0* Usefull for chemysts, teachers & students. Thanks! ### 3/5 — Soooo close!! *2008-09-20, version 0* How do you criticize a free app? You guys are awesome for making this, but PLEASE add in a "desired volume" selector so it's not automatically set to 1 L!! ### 4/5 — Awesome, needs field flexibility *2008-09-09, version 0* I am a chemistry teacher and I love this program- All it needs now is field flexibilty. The most important thing to me is knowing how many grams of a given compound to add to a desired volume to get the molarity that I want. With this, its perfect. Either way, I love the altruism that goes into making a valuable application available to everyone. ### 4/5 — Biologists and Chemists Rejoice! *2008-09-05, version 0* Finally! There are some websites out there that help with this kind of thing, but having something mobile is great! This is just what I need when making solutions in lab. I agree with another comment about field flexibility, (i.e. determining grams needed given volume, MW, desired molarity) but it still works great! ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesnt work *2017-01-21, version 3.0.1* Waste of time! Doesn't work ### 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. ### 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. ### 1/5 — Won't work---just crashes! *2008-09-02, version 0* As above. Needs to be debugged. ### 2/5 — Peccato *2010-08-01, version 0* Dopo l'ultimo aggiornamento non funziona più, si blocca...peccato, era un'apposita carina e utile. ### 2/5 — Very unresponsive interface *2009-07-05, version 0* It would be good if it were usable ### 2/5 — It's okay... *2008-11-01, version 0* Good idea, bad execution. The slide bars are too fiddly! Needs work. ### 3/5 — Does the job *2012-03-22, version 1.7* But it would be nice to have more formulas and useful stuff ### 3/5 — Hmm could be great *2008-10-27, version 0* As an a level chemist this app jumped out at me straight away. As an idea it's great but in reality it is not. I don't really like the slide to change the units it's difficult to use when u need to use it quickly in the lab. Hope it is improved in next update ### 3/5 — Lab Technician *2008-09-20, version 0* This is a great program! Can you incorporate other values like ppb, ppm, etc? Thanks! ## Most praised reviews (10 highest-rated) ### 5/5 — This is best calculator for iphone user *2017-09-24, version 3.0.1* I really really suggest for scientist who need simple and best scientific calculator however it needs upgrade for i OS 11.0 ### 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. ### 5/5 — Very useful and it's FREE!! *2010-05-20, version 0* What more do you want? ### 5/5 — great *2009-11-06, version 0* This is going to save me alot of time in the lab. Thanks a ton. ### 5/5 — great app *2009-01-25, version 0* it really makes your life easier ### 5/5 — More features than I thought! *2009-01-07, version 0* After reading about the app, I downloaded to see if it could help in my college Chem class. This app is so easy to use, and works great! I am supposed to know how to work these conversions, so I use this to double check my work. It's already helped teach me what conversion errors I make. Would love to see more SI units. ### 5/5 — This is so cool!!! *2008-10-18, version 0* This is good apps for chemist. Molality calc. is very annoying. But, this apps very helpful thease works. Thanks for developed this apps. But, I'd more like to that when this apps consider purity of reagent. ### 5/5 — Great ! *2008-10-04, version 0* A very nice and useful application ! The first version was limited, but you can now choose the variable. Useful for students and for tired scientists... Thanks a lot ! ### 5/5 — Well done *2008-09-17, version 0* Great app! My students will love it! ### 5/5 — Thank you! *2008-09-04, version 0* Extremely valuable for working in the lab! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
