Ratings and reviews

Huge improvements after the recent updates. Turn phone to landscape and/or press enter button before entering the ratio will crash the app.

Pretty nice app! It has oz or ML and gives some recommendations on certain products dilutions. Keep up the good work.

Error in that when looking at ml there is not enough space for water output. For example, if you choose 2000ml and 5:1 ratio, output is 333 of product and 167 of water. It should be 1667 if water. There is not enough space in the total water output box to put the whole 1667. Only the 1st 3 digits show. Please fit and otherwise nice app!
