Used this app everyday for years

I can’t say enough good about this app. Fantastic for quickly preparing buffers and dilutions. Saves tons of messy calculator work.

Comment to jeffspc88

As the developer I am sorry that you had such a bad experience. The problem with mole converter was caused by a wrong variable which was set when you did exit the program. The next time you did start the program kDa instead of Da was displayed (or vice versa). Therefore you get mmoles instead of moles. You can test it by yourself by shaking your device to clear all fields. When you now enter the values the correct solution will be displayed. I have submitted an update (1.8.1) to fix this problem. The update will also address the slider issue. In cases when the value was zero it was not possible to change the unit.
However thank you for your valuable feedback and I hope you give the program a second chance.
