Hi everyone - I am Jong Woo Kim, the developer of PhotoSpec Passport.

I built it after seeing people get photos rejected for reasons nobody had told them: the head sat a few millimetres too high, the file was over the size limit, the dimensions were right for one country but not the one they were applying to.

So we spent a long time reading the actual published requirements - government pages and other official sources - for 104 documents across 37 countries. Each value in the app shows where it came from and when we last checked it. Where an authority does not publish a value, we say so rather than assume one.

You can take the photo with either the front or the rear camera. Voice guidance helps position the camera and the person being photographed, and the shot is captured automatically at the right moment. If you are photographing yourself with the front camera, put the phone on a stable stand rather than holding it in your hand.

The app helps you take the photo, not retouch it. After the shot, lighting, sharpness, expression, head position and background are checked using applicable document requirements and photo-quality guidance. The face is not reshaped and the background is not replaced. Everything runs on the phone; the photo is not uploaded to our server.

No ads, no subscription, no locked pro tier. Taking and checking photos is free - you pay only when you decide to save a finished one. Finished photos can be sent as a file, or laid out for printing at home on 4x6, Letter or A4. The app runs in 22 languages.

Three free browser tools, no account needed:

Android is live on Google Play. The iPhone version is in review with Apple and is not on the App Store yet.

I would genuinely like to hear where it falls short - especially if your country requirements are not covered yet.
