Measure
Point. Hold still. Done.
Point your iPhone at someone standing on the floor. A measuring pole appears beside them, and when they hold roughly still, Doorframe captures by itself. A wobbly toddler is fine.
Then it asks "Is this Arlo?", so the height lands on the right person.
Measuring live needs an iPhone with LiDAR: the Pro and Pro Max models. On any iPhone, you can enter a height from a check-up.
Standing or lying down
Switch to Lying for babies.
Plain coaching
"Step back a little." "Show their feet." "Too dark to see. Turn on a light."
Every height shows its range
And how sure Doorframe is, so you know when to measure again.
High confidence
The Doorframe
The whole family, on one door.
Everyone's latest mark, in pencil, on a door drawn to true scale. Tap it for the full door, and turn on history for the kids' older marks in faded pencil.
Then a card for each person, and every measurement in a library you can browse.
Growing up
Watch them grow.
Babies, children and teens get growth charts from the WHO (to age two) and the CDC (to 20), with their percentile and how fast they're growing.
Looking Ahead predicts their grown-up height from their own growth curve, their parents' heights, or both. You choose who the parents are; Doorframe never guesses.
Grown-ups get a steady height card instead of a chart.
Percentiles are information, not medical advice.
Moments
Small things worth noticing.
Doorframe notices how much they've grown, who they'll pass next, and when it's been a while since you measured.
Arlo grew 2.1 cm
Since 5 Jul
Arlo passes Maya at about 14
If they stay on their growth curve.
Arlo may grow to 178.2 cm
Likely 170.9 cm – 185.4 cm. From their growth curve and both parents' heights.
Time to measure Arlo
Last measured 46 days ago.
