So far, very nice app.... clear & concise. Admittedly, saves faffing about calculating on paper. .... bit lazy !

This app is a wonderful tool! Very intuitive, easy to use. I design/build LED drivers and battery chargers frequently as a part of my work. Once I used my calculator and a scratch pad. Now I'm using this app! The 'projects' section is very nice. The entire app is a real gem. Get it on your device and in your pocket because it is very handy!

Ads are VERY intrusive. Crashes on most calculations because ads are being forced. Absolutely horrid. Avoid at all costs.

R1 can only be 120 to 1K ohms when calculating voltage. This app allows you to enter a resistance that is outside of the requirement making you think it will work when it won't.

we can't calculate resistor Values by entering required i/p or o/p voltage also can't Zoom projects circuits

Can't zoom in of projects not enough educational.

We want to calculate R2, but it is not allowed.

New Interface is really nice. Thanks

Simple, easy to use, and nice for screen shots when saving a set of values. It might be nice to see an update with dials for R1 and R2 using active calculation so that I can change the resistors and see how the output voltage is changing in real time. P.s. datasheets for the LM regulators would be nice to see in the app as well.

To support me financially in order for me to have/build a centre for showing or distributing electronic items allover and training youth vocationally and also have show for electronics
