Press kit

Get Tucked is an iPhone app that measures the frontal area of a cyclist and their loaded bike from one photo against a plain wall. Riders compare positions and bag setups in cm². Each reading carries an error bar, and the app says "indistinguishable" when a difference is too small to trust.

How it works

Cyclists spend a lot on aero gear, and the usual ways to measure it are wind tunnels and dedicated sensors. Get Tucked uses a phone photo. The rider stands on the bike in front of a plain wall, a friend takes a head-on photo from 5 to 6 m back, and the rider taps the two ends of the handlebar. The app segments rider, bike and bags on the phone and reports frontal area in cm².

The handlebar is the ruler. The rider enters its width once, and it turns pixels into centimetres.
The wheel is a second ruler. If the two rulers disagree, the app flags the photo.
Every reading has an error bar of at least ±3%. If two setups differ by less than their combined error, the app says "indistinguishable".

It measures frontal area, not drag. It does not estimate CdA or model airflow, and its time estimate is a range. The methodology page gives the full method and a list of what the app can't do.

Screenshots

App Store screenshot: Too small to trust? We say so. Two positions 1.3% apart, inside the noise.

App Store screenshot: 4 to 12 min per 100 km, probably. The time estimate shown as a range.
