Only a very minor criticism - the app doesn't use localization. It is using a comma (, ) as the decimal separator but for Australia it should be a full stop (.) - only around 30% of countries use a comma. Like I said, very minor criticism. It is a free app after all and does what it advertises.

Exactly what I needed. It's very easy to find the correct drill bit needed for the tap you are using.

UI is very clean and user-friendly 👌, but some threading size missing 34× 1.5 pitch mm, 37 mm, and mm big size don't show 1,1.25,1.5 pitches please update it
