### 5/5 — The best!!

*2024-08-08*

The best FREE resistor app…

### 5/5 — Really easy and nice app

*2024-07-29, version 1.3.3*

It is clearly the best resistor finder app

### 5/5 — Nice app

*2024-01-07, version 1.3.3*

Love it just tinkering in circuit boards easy to check resistors 
Can order new with ease

### 5/5 — Orsome

*2023-12-24*

This is realy good for me as I have a bad memory for remembering what resistance matches what colours it’s orsome for anyone like me

### 3/5 — Easy, needs minor fix

*2023-08-16*

App makes it easy to tap colors without spinning a “dial”.

Would be nice if silver & gold buttons had metallic speckle.

I had a resistor where the last two bands were both gold. The value shown was incorrect and had a “G” after it. 

If fixed, I WILL revise this review immeiately.

### 5/5 — Clean and easy to use

*2023-01-16*

Clean design with no frills. Exactly what I was looking for.

### 4/5 — Minor bug (inconvenience)

*2022-12-17, version 1.0*

I’m having a bug whit the app the colors don’t come up right the the yellow and orange are coming up brownish. Hopping that I’ll be fix quickly. Still would recommend to download it.

### 5/5 — Exactly what I needed

*2022-12-11*

It does exactly what I need without any frills which is what I’ve been looking for. Super simple design and really easy to use.
