Iris
$15 one-time (per major version), 7-day free trial
Price checked at source September 18, 2026.
A blue-light filter and screen dimmer with PWM-free brightness control and 9 built-in presets — one-time $15 purchase after a free trial.
Our take
Beyond warming color temperature through the day and night, Iris also targets screen flicker: many displays dim by rapidly switching the backlight on and off (PWM), which Iris avoids by dimming through a different method. Nine presets (Reading, Programming, Sleep, and more) cover common scenarios, plus fully custom color/brightness combinations and ambient-light-matched brightness. $15 one-time per major version, with a 7-day free trial.
