Ratings and Reviews
Wow this is great!
Cannot saw enough. As a hobby electronics builder I can not believe how well this app works. I use the LED and resistor function the most.
Excellent app and creator (vaper friendly)
I can't speak enough how well the app works and looks. Puts all others in the realm to shame. Another plus is now with a watts counter, coil builders can now build within safe limits. A must have for any vaper out there. This came as a suggestion to the creator who is more than willing to hear you out. Simply amazing! Highly recommended.
This app is a great reference tool.
I look forward to any future updates that would add more info.
Hats off to the devs.
