Murrona turns your iPhone's Taptic Engine into slow rhythms you can feel: a cat's purr that breathes and varies like a real one, a heartbeat that can ease down over 15 minutes, a long breath (4-7-8 included), a train on the rails, ocean swells. Tap "Start and dim the screen" and the display goes fully black while the rhythm carries on. Rest the phone on your bed beside you. One-time $4.99, no subscription, no ads, no account, nothing leaves your device. iPhone only.
Outline the roof on a photo — a drone shot, or one taken from the ground. Tegrona Lite removes the perspective by reading the tile pattern, so trapezoid and triangular roof sections work too. It takes the scale from the tile size, fills the roof with panels, and exports an A4 spec sheet for the customer. Free, no account. The web version runs entirely in your browser with nothing uploaded; native apps for macOS, Windows, iPad and Android.
