Nothing you don't.

Six carefully crafted features — no bloat, no distractions.

Log Your Weight

Track daily weigh-ins in kg or lbs with optional notes. Quick, frictionless, done in seconds.

Progress Photos

Attach front and back photos to each entry. Any dimension, full quality, never compressed.

Trend Charts

Beautiful line charts across weekly, monthly, yearly, and all-time periods.

Before & After Slider

Drag to reveal your transformation side-by-side. See exactly how far you've come.

100% Private

Everything lives on your device. No uploads. No cloud. No surveillance.

Face ID Lock

Optional biometric lock so only you can open the app.

How it works

Three steps. That's it.

01

Log your weight daily

Takes under 10 seconds. Add a photo if you want — or don't. No pressure.

02

Watch your trend emerge

The chart updates instantly, showing your trajectory across any time range you choose.

03

Compare your progress

Pick any two entries and slide between before and after. Your transformation, front and centre.

Your data never leaves your phone.

Periscope stores everything — your weight history, your photos, your progress — in a local database on your device. We don't have a server that holds your data. We can't see it. Nobody can.

Apple Sign In is used only to create your account. Your Apple ID email is never shared or sold.
