Works great

There's a glitch with Apple regarding the complication. Hard press on your Apple Watch face and hit the button "customize" and the complication will show up and you can add it there. This problem is quite prevalent with watch apps but this work around will get them all working for you.

Thanks for a great app.

Waisted 2 hours

trying to gat this app to work properly. The installation went ok but using it didn’t.
1. There was no way to clear the Calculator. No ‘clear’ button.
2. Tip Calculator, I see where you had to scroll the tip % and bill boxes but they didn’t work.
3. Conversion Calculator, same thing with the boxes at the bottom, they would not scroll.
4. The iPhone portion, the color scheme was a very poor choice. Maybe choose a scheme with more contrast
I removed it, I may check back in the future to see if it has been fixed.
