Awesome program, works as intended. --- 4 Stars; Delivered as expected. --- 5 Star Suggestion: 1. Add an option for percentages with the gallon. 2. Add an option to add other chemicals such as.. surfactant to the mix. 3. Add option to change (HS) to degreeser ect..

Doesnt allow to change from gallons to ltres ..pretty basic ...ideally it should tell you what % you should use for brick work...concrete...roofs....soft wash etc.
