The scale bounces.
You're trending down.
Lentra lines up your progress photos in the same spot, turns your daily weigh-ins into one steady trend, and puts it all on a single page you can hand your doctor.

Line up your photos.
A faint outline of your first photo sits on the camera, with a level and a step-back cue, so week 37 lands where day 1 did. A self-timer means no awkward arm.
Then scrub between any two weeks, or play the whole run as a timelapse.
See through the noise.
Water, salt and sleep can swing the scale four pounds overnight. Lentra smooths the daily numbers into a trend line, so one bad morning doesn't feel like a lost week.
On a GLP-1? Log your doses and they show up as markers on the same chart.
One page for your doctor.
Start weight, trend, rate of change and dose history on a single clean PDF, ready for an appointment or an insurance renewal.
Lentra records what happened. It doesn't estimate doses or give medical advice.
