Comments on Electronics Toolbox Pro for Android

★★★★★ Mike Lee · Apr 21, 2025

This app is very in depth indeed, covers a heck of a lot. It's been very useful many a time. Well done for such a great help in the field of electronics. I would happily pay £5.00 for this app.

★★★★★ Robert Kelso · Jul 11, 2024

Let me start with the bad things about this app...... I really cannot find any. Really well done and well worth the little it costs for pro version. I still have the non-pro version on my phone too.
