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

No detailed calculation. Constricted functions. Not fully calculable. You could have provided columns in which R1, R2 C, & % could be substituted to find a value or values. You deserve more star for your concern. I will be watching to add more stars, you have tried. Good luck.

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.

I thought this was going to give me the component values to use for the timing parameters I want. Instead I have to work this app backwards to approximate numerous times until I get somewhere near what I need.

This is a great app for practical applications of the 555 timer. It has helped me design a few good circuits for home automation.

great app, although most of its calculations are rounded of specially in high time and low time but im still giving a 5
