Kululu vs Memories Online
By Trevor Holmes, Founder, Memories Online · Published
I built Memories Online, so this comparison is biased — but the bias should not stop me from being honest about Kululu. Kululu and Memories Online both end up in the same Google searches for couples planning weddings, but they actually solve subtly different halves of the problem. This post lays out what each one is built for, where the real differences are, and which kind of wedding each fits best.
If you are still narrowing options across the whole category, the best wedding slideshow apps for 2026 listicle compares all nine apps in one ranked view.
What Kululu does well
Kululu is positioned more as a wedding-photo-sharing app than a slideshow player, and that positioning is its strength. Guests upload photos via a share code; the photos collect into a shared album that lives on after the wedding. The album is the primary product. The slideshow playback exists but is secondary — Kululu treats it the way Google Photos treats slideshow mode: a viewing option for an album you are mainly using as a library.
For couples whose primary goal is the photo collection and the long-term shared album, Kululu is well-built. The album interface is cleaner and more browsable than what most slideshow-first apps ship, because the album IS the product. Guests who keep contributing photos in the days after the wedding (tagging themselves and others, adding their own captions, dropping in photos they took on the morning of the wedding before they got dressed) have a more polished experience than they would in a slideshow-first app.
The brand is also in a different place than most of the competitors. Kululu has invested in mobile-first guest UX and an album view that works as well on a phone in a guest's hand a week after the wedding as it does on the venue projector during the reception. The slideshow playback is fine; the album is where Kululu has put its design effort.
Pricing is one-time-per-event. Generally a similar tier to other paid apps in this space — around a hundred dollars for a wedding-sized package.
Where Memories Online is different
The fundamental difference is the emphasis. Kululu treats the album as primary and slideshow playback as supplementary; Memories Online treats both as first-class peers, with the slideshow built explicitly for live-during-the-reception playback.
The practical implications:
The slideshow itself plays differently. Memories Online's slideshow is designed to run as a continuous loop on a screen during the reception, with smooth crossfades, customizable themes, and a Spotify-paired audio track for the music side of the experience. Kululu's slideshow is closer to an album-viewer-in-presentation-mode — it plays, and it works, but it does not have the same "this is the centerpiece visual at the reception" production polish.
The free starting tier is the second practical difference. Memories Online has a free tier with no credit card required; Kululu is paid from the first event. For couples doing destination or budget-conscious weddings, the tier matters. For couples already comfortable with a per-event fee, the price difference is small.
The third difference is occasion coverage. Memories Online ships an explicit memorial / celebration-of-life mode designed for the dignified pacing a memorial service needs (softer accents, no exclamation marks in default copy, slower transitions). Kululu is wedding-focused and does not have an equivalent preset. If the same family wants to use the same app for both occasions — a wedding this year, a memorial slideshow when a parent passes — Memories Online covers both; Kululu covers the wedding well and is a bad fit for the other occasion.
The fourth difference is the slightly different relationship to long-term photo retention. Kululu's album-first design means photos are designed to live on as a permanent library; Memories Online keeps the album available too but the design center of gravity is on the live-event experience. Both keep photos accessible afterward — the question is which side of the timeline matters more.
When to pick Kululu
Pick Kululu if your primary goal is the long-term shared album rather than the live-on-the-screen experience. If you imagine guests opening the album a year later to relive the wedding, and the during-the-night slideshow is a "nice if it works" rather than the centerpiece, Kululu fits. The album-first design pays off in the months after the wedding more than the slideshow-first design does.
Pick Kululu if your wedding is small enough that the live slideshow on a screen is not a key visual element of the reception space. Backyard weddings, intimate dinners, and elopements often do not have a projector or a TV at all — in which case the slideshow-first features of Memories Online are unused budget and the album-first design of Kululu lines up better with what you actually need.
When to pick Memories Online
Pick Memories Online if the live slideshow at the reception is a planned visual element. Big-tent weddings with a projector, ballroom receptions with venue screens, and outdoor receptions with a projection wall all benefit from a slideshow that grows in real time and ties the room together visually. That is the explicit design center of Memories Online and the album survives afterward as a bonus.
Pick Memories Online if budget matters and the free starting tier is meaningful, or if you might also need a memorial slideshow flow for a different family event, or if you want a single vendor that covers both ends of the family-events spectrum.

Frequently asked questions
What does NOT differ
A few questions worth answering quickly because they keep showing up in comparison searches and the answer is the same for both apps. Both Kululu and Memories Online support guest video clips alongside still photos. Both work fine on cellular when venue WiFi is unreliable (most photo uploads happen over LTE or 5G regardless of which app you pick). Both let the host moderate uploads before they hit the slideshow rotation. Both keep the share code active for several weeks after the wedding so late uploads from guests who got their phones to charge are still possible. Both export to a printed photo book at the end.
In short: the wedding-day fundamentals are functionally equivalent. The differences that matter are the design center of gravity (slideshow-first vs album-first), the free starting tier, and whether you need memorial-mode coverage for other family events. Pick on those criteria; the rest is roughly the same on both apps.
Bottom line
Kululu and Memories Online overlap a lot but have meaningfully different design centers. Kululu optimizes for the album that survives the wedding; Memories Online optimizes for the slideshow that plays during the wedding (with the album as a bonus). Pick based on which side of that timeline matters more for your wedding.
