How Once Works: 1. Create a film for your event and set the rules 2. Share a QR code or link so guests can join in seconds (No download needed for guests) 3. Everyone shoots in the moment with limited shots per person 4. Photos unlock together at the time you choose, ready to relive and save Why Hosts Choose Once: - QR join, no friction: Guests can join with or without the app via App Clip. - Shared camera for the whole group: Centralize every candid and POV in one place. - Limited shots = better photos: Scarcity encourages thoughtful, story-driven captures. - Delayed reveal: Unlock photos at event end or a custom time to keep guests present. - Private by default: You control access, visibility, and downloads. - Host controls: Set shot limits, reveal mode (instant or delayed), and participant caps. - Download everything: Save full galleries to your device or archive them for later. - Beautiful “film” feel: Subtle, tasteful looks that keep skin tones and ambience true. Perfect For: - Weddings and receptions - Bachelor/Bachelorette parties and showers - Birthdays and reunions - Group trips and retreats - Team offsites - School events, clubs, and fundraisers We Care About Your Privacy: Your event gallery is private by default and controlled by the host. We do not sell your data. See our Privacy Policy at once.film/privacy. Support: Questions or feedback? Please feel free to reach out to us at hello@once.film Life happens only Once. Make sure to capture every angle of it.

Flash is the digital disposable camera for events. Your guests scan one QR code, shoot a limited roll of photos, video clips and voice notes — and nobody sees a single frame until you reveal the album. No app for them to download. No feed. No spoilers. Just the whole night, through everyone's eyes. ONE QR CODE, EVERY GUEST Create your event in seconds and share a single QR code. Guests are shooting within ten seconds — no account, no download, nothing to explain. A LIMITED ROLL, LIKE THE REAL THING Give every guest a fixed number of shots. Scarcity makes people look before they shoot, so you end up with fewer photos and far better ones. HIDDEN UNTIL THE REVEAL Every photo, video and voice note stays locked until you develop the album. Nobody scrolls the party on their phone. Nobody spoils the surprise. The reveal becomes a moment of its own. PHOTOS, VIDEO AND VOICE Capture more than stills. Short video clips and voice notes catch the speech, the laugh and the song everyone screamed at 1 a.m. FILM LOOKS BUILT IN Retro, flash-lit filters that make a modern phone camera feel like a single-use camera from the corner shop. MAKE IT YOURS Name the event, design the cover, choose the roll size and decide exactly when the album develops. MADE FOR • Weddings, receptions and rehearsal dinners • Birthdays and milestone parties • Bachelor and bachelorette trips • Festivals, club nights and after-parties • Holidays and road trips with friends • Corporate events, conferences and team days • Baby showers, graduations and christenings FROM IDEA TO ALBUM IN THREE STEPS 1. Create the event and set the roll size 2. Share one QR code with your guests 3. Reveal the album and download every shot in full quality WHY GUESTS LOVE IT They keep their own phone and their own camera roll stays private. They only share what they shot inside Flash. No sign-up, no endless group chat the morning after. WHY HOSTS LOVE IT You stop being the only person with a camera. You wake up to hundreds of photos you could never have taken yourself — from the dance floor, from the kids' table, from the taxi home. PRICING Small events are free. Larger events and extra capacity are available as upgrades inside the app. Flash is built in the EU by m4ntech.

Verdict
The clearest difference is ads: Flash at none against Once's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Once sells 18 one-off in-app purchases and Flash sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
