Wow, just perfect
Simple is as simple does, this app translates the resistor color codes to numeric form on one easy-to-use page; I love it.
Caution: you really need a reliable multimeter to verify that the resistor you have actually measures correctly, as it may have been overheated or otherwise incorrect.
Your green colour look so poor can you make it more brighter please
Why does it want access to Bluetooth?
After upgrading my phone I found that this app is wanting to access my Bluetooth connection. Why? No good reason lots of bad ones in terms of privacy but maybe I shouldn’t be surprised with it being a free app. The user is the product being sold.
With Family Sharing set up, up to six family members can use this app.
