Motionwell keeps what's on your screen level with the horizon and gives your peripheral vision a steady, moving reference — so the ride stops turning on you. All on-device. Works offline.
iOS 17+ · No account · Your motion data never leaves the phone
The road unspooled north, and for the first time in years she opened a book in the passenger seat without the old dread rising in her throat. The words held still. Steady, page after page, as the hills rolled past the window in a soft blur she no longer had to look away from.
That mismatch is what makes you sick. Motionwell ends the argument by giving your eyes the same motion story your body feels.
You stare at a fixed screen while the car turns and dips. Your eyes read "still," your inner ear reads "moving" — and twenty minutes later you're looking up green.
Content stays level with the horizon while soft dot columns at the screen's edges track every turn and dip. Your peripheral vision gets a stable, moving reference — the same cue that stops the sick feeling.
Motionwell slips into the right mode based on the app you're using — or switch anytime from a quiet little pill. A manual override always wins.
Video locks to the horizon and the side dots run wide and slow — your eyes stay on fast-moving content while the cue does the balancing for you.
Text auto-levels and the dot rhythm is gentle. Line-tracking dampens the jitter of a bumpy road so you never lose your place mid-sentence.
Cursor and keyboard are stabilized and the cue field tightens to hold your focus — a calmer, low-distraction field for getting real work done.
It's all on-device sensors — no signal required. Keeps working through tunnels, on planes, and out on remote roads.
A resting "Reading · 23m" pill floats above what you're doing. One tap to hop between modes without leaving the page.
Six curated low-glare tones — butter, cream, powder, sand, stone, slate. We keep alarming reds and greens out on purpose.
A gentle nudge to close your eyes for 20 seconds and let your inner ear catch up — with rotating comfort tips. Fully opt-out.
No account, no cloud, no tracking. Your motion data is processed on the phone and never leaves it.
Your iPhone becomes the Mac's motion sensor, leveling your laptop's content — planes, trains, and back-seat work.
"Eyes up — we've got the horizon. Read, reply, watch away."
