What it does

Stock-grade photos.
Proof of place built in.

Most third-party cameras look worse than your stock app because they skip the manufacturer’s computational pipeline. Meridian borrows it — and adds precise, honest geotagging on top.

Stock-grade quality

Taps your phone’s own computational-photography pipeline via CameraX Extensions — real multi-frame HDR & Night mode, not a hand-rolled imitation.

Precise geotagging

Clean GPS EXIF — latitude, longitude, altitude, bearing, timestamp — written straight into every capture. Warm location means never “location: unknown”.

Optional visible stamp

Burn coordinates, address, altitude and time onto a separate copy. The full-quality master always stays untouched.

Photo, Video & Portrait

Full capture modes with a recording timer and depth-aware Portrait — all under the same Apple-Camera-style controls.

Share-proof & private

Generate a scannable QR proof of a shot — or strip location entirely on share, which actually removes the metadata.

Pro controls

Tap-to-focus, exposure compensation, flash, HDR/Night strip, grid and lens flip. RAW/DNG-ready for when you’re on real hardware.

How it works

From install to geotagged in a minute.

  1. 01

    Download

    Grab the APK — or your store of choice. No account, ever.

  2. 02

    Grant camera + location

    One-time permission. Location warms up the instant the camera opens.

  3. 03

    Shoot geotagged photos

    Every shot carries clean GPS EXIF. Toggle the visible stamp when you need proof.

Truly open

Two builds. Both fully open.

100% of the UI, capture and EXIF logic is shared. Only the location source differs — so the foss build ships with zero proprietary dependencies.
