## What is iTronixLite?

A free tool for electronics enthusiasts. 

This app does NOT have any InApp Purchases. It is ABSOLUTELY FREE!

Features:
* 4,5,6-band resistor color codes translation from value entered and vice versa. 
* Fast value entering, to enter 1000Ω, you just key in 1 and tap the kΩ button.
* For the 4-band tool, it also displays equivalent value of Ceramic Capacitors, Electrolytic Capacitors, Inductors and chip resistors. Also available a tool to translate Electrolytic capacitor's voltage rating codes.
* Ability to detect if the resistor value chosen is of EIA Standards or not.
* If value entered is not found, the nearest value will be shown.
* Shows the color codes in words, to prevent misinterpretation of colors. 
* A simple flashlight (with 4 colors - white,red,green,blue). Useful for video color referencing. Starts always with a white light. The light is particularly useful if you are soldering away in a dark place or cannot find that component that just dropped from the table.
* A free inverting op-amp calculator.

If you like iTronixLite, check  out iTronixPal (Paid Version) which features more functions and continuously updated.

### 1/5 — Crashes

*2022-10-17*

App won’t even open

### 1/5 — Failed to start

*2022-10-11, version 1.5*

Fails to start. Been using it for more than 10 years, upset at what happened.

### 5/5 — App keep crashing at startup

*2022-03-17*

Could you please update this little handy app as it keep crashing at start up on a iPhone X. 
Thanks.

### 2/5 — Locks up on info page

*2018-03-11*

Titles says it all really. Keep away from info button and it appears to work. Not blown away with resistors and capacitors all crammed onto one page though. Better free tools out there.

### 1/5 — Intrusive ads

*2018-01-09, version 1.5*

Full-screen video advertisements **with sound** appear at startup and when switching to a different function. Additionally the Lite version is not very useful: It just interprets resistor codes, and its op amp feature can be done by ANY calculator.

### 5/5 — Color code tools PERFECT

*2014-09-23, version 1.5*

as someone who works with electronics circuits on DAILY BASIS,
this app is great - helps me find a particular standard resistors/caps.
definitely will buy the Pro version!

### 5/5 — Thaaaaaanks

*2013-04-10, version 1.4*

It is usefull prog.

### 5/5 — Too, too handy...

*2013-03-11*

After using this I am teased into wanting the full version - just to get rid of the ads!  Oh ya, and it's handy...

### 5/5 — Awesome

*2013-03-09*

It helps very much to use the right component. Cool.

### 5/5 — Mr

*2013-01-05*

Brilliant app for ham radio operators
