Rollo turns any wedding, trip, or party into a shared disposable photo roll. Guests join with a QR or code, shoot only inside the app (no gallery uploads — no spoilers), and photos stay hidden until the organizer’s reveal time. Then the whole album unlocks at once. Free to start (up to 5 guests). Pay per event for more capacity — no monthly subscription. GDPR-friendly, no ads, no tracking. Now launching on iOS (App Store review). Android coming to Google Play.
