Soldi buttati ### 1/5 — Non funziona più! Crash all'avvio! *2012-02-13, version 2.4* Era ottimo da 4 stelle ma ora non funziona più. Crash subito all'avvio. E magari anche qualche miglioramento grafico e di utilizzo. Per ora 1 stella sino al ripristino!!! ### 3/5 — Good, but a couple of fixes needed *2008-09-13, version 0* Two fixes that would benefit this app are 1) less sensitive color bands. Perhaps a scroll list (drop-down) as 1 reviewer mentioned. Also, 2) make the colors solid. The graphic in the background is nice, but with the translucent color bands, can be a bit detracting. Overall, though, very useful. ### 1/5 — Nice idea, poor user interface *2008-09-11, version 0* The concept of the app is great, but to change the colours you have to slide your finger sideways across each colour band. The sensitivity of movement is such that you only have to move your finger ever so slightly and the colour changes which maks colour selection very difficult. In short a poor user interface! ### 2/5 — ok app *2008-09-06, version 0* it's definately hard to select the color I think they should of had some sort of scroll down menu if you just tap on the band ### 1/5 — Great idea, poor implementation... *2008-09-03, version 0* Instructions are to swipe the band to change the value/color. You can move your finger less than 1/4 of an inch, and cycle through ALL possible colors - VERY difficult to select the color you want. I can't imagine it would be that difficult to make the swipe less sensitive - and no compelling reason to use a swipe beyond the "gimmick" factor in my opinion. Fix that, and it becomes at least somewhat useful - would also be good to have the ability to put in a value, and have it show you the resulting color code. Again - great idea, and I was excited when I found it, but am taking others advice and getting "iResist" instead. ### 3/5 — Great Idea *2008-09-03, version 0* Handy but a little hard to change the band colours ### 5/5 — Spettacolare!!! *2008-09-02, version 0* Ottimo programma GRATIS che può aiutare molti studenti nei laboratori di elettronica con qualche difficoltà di memoria... da avere! ### 5/5 — SLIDE! *2008-09-01, version 0* Touching the strips doesn't work, BUT sliding/swiping over them does! Great little app to have in your pocket if electronics is your thing. ### 1/5 — FAIL *2008-08-31, version 0* Very buggy. Doesn't even load!! ## Frequently asked questions about iResistors ### What is iResistors? iResistors is an educational app designed to help users learn about resistor color codes.
