Scrawlight

A sign you can still write ten minutes before the encore. Scrawlight turns your handwriting into a glowing light board. Turn the phone sideways, write with a finger, watch the strokes light up, then let them scroll across the full screen. Switch on the mic and your words burst with the drums and breathe with the music. Write anything: a name, a happy birthday, "I've waited three years for this," or just "over here!" —— HOW IT WORKS —— 1. Turn the phone sideways and write. Go as long as you like — the canvas keeps growing to the right. 2. Pick a glow, a stroke weight, a backdrop. Five glows, from neon pink to electric cyan, plus a rainbow that flows along the stroke. 3. Raise it. Full-screen scrolling, three speeds, and the screen won't lock while you're showing it. —— IT MOVES WITH THE MUSIC —— Turn Wave on and the mic listens to the room: · Burst — the drums hit, the letters fly apart, then spring back home · Ripple — rings of light roll outward along the strokes · Breathe — the glow swells with the volume; easiest on the battery —— TWO PENS —— · Marker — a solid band of light, exactly as you wrote it · Neon — a hollow tube with a glowing edge; strokes straighten themselves like a real sign (Pro) —— YOUR WORDS STAY YOURS —— Scrawlight collects no data. No accounts, no ads, no third-party SDKs, no analytics. The microphone is used only while Wave is on, and only analyzed in memory, in real time — never recorded, never saved, never uploaded. Your boards sync through your own private iCloud database: that's Apple's service, the data is yours, and the developer cannot see it. Turn sync off in Settings and everything stays on this device. —— ABOUT PRO —— Scrawlight Pro is a one-time purchase. It unlocks the Neon pen and every Pro style added later. No subscription, no renewals. —— —— Requires iOS 18 or later. iPhone only for now; iPad support is on the way. Write it, raise it, let them see.

Verdict
The clearest difference is ads: Scrawlight at none against PetsAge's shown. Scrawlight also leads on update cadence (fortnightly vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
