Liquid Calculator

An application that is meant to be a compendium of knowledge on the mixing liquids (e-liquid), e-smoking and e-cigarrettes.
As of today, version 1.0 has the following features:

1) Counting the power supplied to the mixing of two liquids.

2) Counting the power supplied to the addition of glycerol.

3) Calculating the amount of components required to obtain specific volumes of liquid a particular strength and glycerol content

4) List of tips for every e-smoker, in particular, for "mixers". Each user can easily write to me, in order to add your own tips

5) Widget, whose task is to calculate the residual liquid: (user specifies how much liquid daily consumes and what its amount of features.)

I added every effort so that it works seamlessly on any device from version 4.0. However, this is my first app and I'd be lying saying that it will work perfectly. Therefore, please inform me about bugs via e-mail message.

I am very happy that I can share useful to every e-smoker app and I do not regret the time I spent on it. I have a lot of plans for the expansion of application, mainly using your suggestions.

I do not want to "clutter" by adding commercials, because as we all know - they simply can not be stand. Users able to help are willing to donate a small financial grant for project through PayPal (link available from within the application). The amount I paid for the placement of application in the store is $ 25 and I would like to (at least partially) recover it because the unplanned expense was for me quite problematic. Thank you very much for help. It will be a sign that it is worthwhile to continue working on this project and my work (a minimum of 200 hours, which is not missed) was appreciated.

Thanks for Monika P. for translation help :)
