@frassmith There is a paid version with more functionalities, but yes, this is free.

@frassmith The product improved a lot in the last year. Give it another try https://www.producthunt.com/post...

@sign Blue light is actually more of a trouble for eye strain https://iristech.co/blue-light There is also PWM flicker https://iristech.co/pwm-flicker which Iris also removes. You can read the benefits over f.lux here :) https://iristech.co/best-alterna...

@mubashar_ali f.lux doesn't let you block certain websites, track your blinking, offer exercises, etc. Yes, the core features are similar, but lets not conflate the massive differences in the pro version of Iris from the very basic features f.lux has.

@dereksilva @mubashar_ali Does Iris actually do blink detection? The User Manual has a section on "Blink Detection" with lots of text on the benefits of blinking and nothing - zero - on the Iris functionality.

@mubashar_ali On the Iris homepage, I listed the benefits of Iris https://www.producthunt.com/post... Also, you can see this comparison article https://iristech.co/best-alterna...
