LabCal

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!!

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. <br/><br/>Would love to see more SI units.

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.

Awesome, easy to use app. By far better than the other five lab calculator iPhone apps I tried.

Really helpful at the bench. Why calculate molarity manually when you can use a computer.

What more do you want?

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!

This is a great program! Can you incorporate other values like ppb, ppm, etc? Thanks!
