This is great for my 9 year old to learn electronics. There is a bug with larger font sizes on my phone, it cuts off some of the text for the 2 rows (2.7K / Band 1 Band 2 etc). ### 4/5 — great tool. *2023-09-13* not sure why theres any tracking on an app as simple as this. ### 2/5 — Bom *2023-01-27, version 2.0* A única coisa é uma cor que está errada que é a rosa. Não é rosa e sim tem que ser a cor violeta e com isso eu classifico como bom. ### 1/5 — It says it supports 5 bands but can only access 4. *2022-12-21* There is no settings button, gear, preferences, etc., that I can find. Only shows 4 bands. Not sure how to change to 5 bands. ### 1/5 — Travou a conexão com a internet *2022-05-24, version 1.2* Instalei no iPhone XR e travou a navegação na internet. O aparelho conectava tanto na rede qto no Wi-Fi, porém não navegava. Até descobrir, resetei, paguei para uma loja destravar e voltou a travar qdo reinstalei. Foi qdo descobri que era esse App o causador da lambança. ### 3/5 — Weird notation *2022-04-01* Why would I want to know what 1.5x10^5 ohm is? Couldn’t there be a way to swap to just say 150k ohms? It is a nice app, otherwise. ### 5/5 — sr7 *2021-12-17, version 1.2* Siuuu ### 1/5 — Not impressed *2021-10-13, version 1.2* Not good at all mate fix it scammer Scam Scam Money grabber ## Frequently asked questions about Resistor Code Calculator ### What does the Resistor Code Calculator app do?
