I felt good paying the 2$ to support the developer of this app. However, I have some suggestions that I feel will greatly improve the app itself. First: for the ingredients section, it should deliver results that contain combinations of the ingredients rather than requiring all the ingredients to be in the drink. Example: I list four ingredients, but the results say there are no drinks with all the ingredients. What it should do instead is deliver results that contain, say, ingredients A and B for one drink, then another drink with ingredients A, C, and D, and maybe another one with B and C. That way it doesnt restrict the results by requiring the drink to contain all four, because oftentimes this will lead to no results. Also this will allow people to simply list the drinks they have sitting in their liquor cabinet and see what they can make even if it doesnt use all of them at once. That was what bothered me most, but mostly everything else works fine.
Secondly, when adding ingredients there is a slight visual glitch that makes the "show results" button to appear at the top rather than the bottom.
Thats all I have to report for now, all in all I am loving the app aside from my first and chief complaint. I would be very excited to see that addressed in a future update and I am confident it would greatly boost the usefullness of this app. With that fixed I would give it a 5/5.
