Ratings and reviews

Good for a quick time or circuit, easy to use

I have not had any problems with this app. I only occasionally use it, but would not be happy about erasing it from my phone. I used the app today to make a turn signal flasher for a scooter. I like the app has circuit applications. If you're bored and just want something to do and have some 555 chips there is weeks and possibly months of fun u can get from this app. Thanks

This is an excellent handy little tool for adjusting 555 timer chips. If u build any circuits using them, you absolutely cannot go wrong by installing this.
