Remember disposable cameras? The waiting. The not-knowing. The little envelope of prints that always held a few surprises. 21Pix brings that feeling back — through your phone, but with real photographs that end up on your doormat. HOW IT WORKS You get 21 shots. Frame each one through a tiny viewfinder — no live preview, no filters, no deletes, no retakes. When the roll is full, order your prints — they're printed on real 10×15 cm glossy photo paper and shipped to your address. A few days later, an envelope lands on your doormat. You open it. You see what you actually shot. Some are great. Some are blurry. All of them are surprises. WHY YOU'LL LOVE IT - No previews, no retakes — Shoot blind. Discover later. The wait is the feature. - 21 shots per roll — A hard limit makes every frame matter. The same number of exposures as a classic disposable. - Real photo prints by mail — Premium 10×15 cm photographs on real photo paper, shipped across the EU. Not pixels. Paper. - Slow on purpose — Mechanical shutter sound, real shake on capture, no previews and no retakes. We rebuilt the whole ritual. - Private and ad-free — No tracking, no ads, no AI scraping, no behavioural profiling. Photos are deleted from our servers after we print them. - Made in the EU — EU servers, EU printing, ships across the EU. WHAT LANDS ON YOUR DOORMAT Real 10×15 cm prints on glossy photo paper. Made for fridges, shoeboxes, and the back of a bedroom mirror — not for feeds. Hold them. Stick them up. Mail them to someone. WHERE WE SHIP Across the EU: Netherlands, Belgium, Germany. More countries coming. PRICING The app is free. Each roll's price covers 21 prints on real paper plus shipping to your door. Final price shown before checkout. No subscriptions, no hidden costs.
