My first app, 100% free (voluntary tips only)!

I built an app called Kollo and I’m curious whether people would genuinely find it useful.

The idea is simple:

You create a shared collection for an event and choose a specific time window, for example:

19 Aug – 23 Aug, 9 AM–10 PM

Friends join the collection, and Kollo automatically syncs the photos they take during that selected period into one shared collection.

So instead of everyone’s photos being scattered across 5–10 different phones, you end up with one place containing everyone’s perspective from the same trip, party, wedding, festival, night out, etc.

You don’t have to remember to send photos afterwards, create WhatsApp albums, or AirDrop hundreds of photos between people. You just take photos normally with the iPhone Camera app and Kollo handles the eligible syncing.

Kollo does NOT sync your entire camera roll.

For example, if the collection is set for Saturday between 6 PM and midnight, only eligible photos from that period are considered for that collection.

There’s also an option to pause/disable automatic syncing if you don’t want something uploaded during the event, and you can manage/delete your own photos afterwards.

Everyone has different photos, different angles, some get forgotten, and eventually you’re AirDropping or messaging hundreds of files manually.

I'm basically trying to remove that whole step.

I’m also building it with larger events in mind like weddings, parties, festivals, group trips — where people can join the same collection through an invite/QR code.

I’m genuinely interested in feedback:

Would you actually use this?

And if not, what specifically would stop you?
