User Reviews

Users appreciate the app's usefulness in calculating coils and inductance for DIY projects and find it helpful and affordable, especially the paid ad-free version. However, many report serious issues such as excessive ads after each calculation, incorrect or unreasonable calculation outputs, inconsistent unit usage, and instability with crashes or usability problems, diminishing overall satisfaction.

Pros

Helps in estimating coil form sizes and inductance for projects.
Works perfectly and is very helpful for users.
Affordable paid version available that removes ads.
Good for experimenting with dividing networks and coil calculations.
Some users find it useful and worth the purchase.

Cons

Excessive and intrusive advertisements after every calculation.
Calculation results are often incorrect or unrealistic, leading to confusion.
Inconsistent or unclear units used, mixing inches and millimeters without clear indication.
App crashes or does not open properly on some devices.
Difficult to use and not user-friendly according to some users.

Something is seriously wrong with this app. I am making copper coils (inductance) for a Crystal radio, I input my information, coil form length, micro Henry's (uf) goal and everything else and this app will come up with crazy numbers, for instance my target is 350uf on a 2" coil and it tells me I need 67.000miles of copper wire and a form 30,000 ft long etc... LMAO no I only need a 4" long coil, with about 50'ft of number 24awg copper wire. Something is definitely wrong here.
