Comments on Timer IC 555 Calculator for Android

★★★★★ Roger Hale · Nov 13, 2019

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 circuited 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

★★★★★ Stephen Paul · Jun 1, 2022

This is one of those apps that you read on the loo, it's very inspiring.

★★★★★ Raid Hhi · Sep 26, 2019

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.

★★★★☆ Al Wristen · Jun 27, 2021

Had enough circuitry using 555 to be instructive and useful.

★★☆☆☆ Rudo Strydom · Jan 7, 2021

There are a few mistakes. On astable t high = 0.69 (Ra+Rb) C, not 0.69 (Ra) C. T low is correct. T low = 0.69 (Rb) C Also on frequency f = 1.44 / (Ra+2Rb) C or 1 / 0.69 (Ra+2Rb) C, Not 1.44 / (Ra+Rb) C. In t high Rb is missing in the equation. In frequency, Rb is times 2.

★★☆☆☆ Kassim Abba Dandago · May 30, 2020

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.
