Comments on Coil Calculator for Android

★★★★★ Andrew Taylor · Dec 3, 2020

A good calculator. Get the paid version its cheap and gets rid of the ads. Perfect and 5 stars.

★★★★★ eDSeLexIE · Dec 8, 2020

This app helps me a lot experimenting my dividing network. Helps me to estimate my coil form sizes, and it's inductance. From scrap materials, I finished my speaker project with this app.

Convenient, need an update? __For calculations for four and six core parallel wire single coils. Need a calculator here.

★☆☆☆☆ Eric Dee · Aug 17, 2024

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.

Every little change results in yet another ad. Utterly ridiculous amount of ads. Removed ap as a result. I wouldn't mind one ad when opened. I wouldn't even mind one add every few calculations. But every single calculation literally makes me see another ad. No, no, thanks, hard pass. There are dozens if not hundreds of online calculators that don't display any ads, so no real reason for such an ad laden app. For me, it's a hard pass. One star because of the insane amount of ads.
