User reviews

I would like a refund

Nothing on here that I can’t get online. Would rather look up the exact part rather than dig around on this app for something that isn’t there.

What an amazing app EE Toolkit excellent well done

Language support

This app is good but it doesn't support multi language. I’d like to order the pro version if it supports Chinese language.

Engineer

Like the layout of the app. Not many apps follow the users own preferences and content as if they developed it.
Can I make one request that would almost complete toolkit?
Add a toolkit for busbars. DC and AC, copper primarily but also other materials like aluminum. This may be a personal preference but I think other Engineers using this app may find it useful as a quick estimate. Be sure to include compensation for temperature, power loss, dissipation, airflow if forced air is used, as in an enclosed environment TPM.

Keep the updates coming

I used this app for an opamps class. It was useful. Please keep the formulas and stuff coming. It didn’t cover everything. Also, thank you for not collecting and selling our data.
