The short answer
Liff Happens lets attendees browse photos of found items and claim theirs, and it brings people: on-site setup, hardware, training and post-event fulfillment. Boomerang keeps found items private, matches each guest's description against inventory with AI, and asks both staff and the guest to confirm before anything ships.
Boomerang may suit you if
- You would rather not show IDs, cards and phones in a public gallery
- You run a year-round venue, or several, as well as events
- You want analytics, revenue share and prohibited items in the same portal

Job by job
Privacy and verification
Public photo galleries expose your inventory, let people see details and falsely claim items, and are not best practice. That matters most for wallets, IDs, payment cards and phones. Boomerang keeps inventory private and secure, and matches items through verified claims: guests describe what they lost, and staff and the guest both confirm before anything is released.
Matching at festival scale
After a big weekend there can be thousands of items and claims. Boomerang matches the moment an item is logged or a claim comes in, reading photos, descriptions, dates and locations, and ranks likely matches for one-click review. Guests with an AirTag can share its location through a true Apple Find My integration, approved by Apple. No other platform we compared has one.
Beyond the weekend
Many event operators also run venues. Boomerang handles both from one account, with separate locations, storage, branding and reporting, and a guest's claim keeps updating after the gates close.
Switching to Boomerang
For a recurring event, we set up locations and storage before load-in, add your claim link and QR signage, and run a 30-minute kick-off with the team. Open inventory from past events can be bulk imported.

Questions
Can attendees browse found items in Boomerang?
Public photo galleries expose your inventory, let people see details and falsely claim items, and are not best practice. That matters most for wallets, IDs, payment cards and phones. Boomerang keeps inventory private and secure, and matches items through verified claims: guests describe what they lost, and staff and the guest both confirm before anything is released.
How do you stop the wrong person from getting an item?
Two checks. Your team reviews every match side by side and can ask the guest a question from the claim. Then the guest sees the same details your team logged, like photos and where it was found, next to what they described, and approves or declines before anything ships. Every decision is logged.
Does Boomerang handle prohibited items at the gate?
Yes, with KeepSafe. Guests scan a QR, snap a photo and drop the item in under 30 seconds. Your team reviews it later, and the guest pays to ship it home or chooses pickup.
Can we bring our existing inventory over?
Yes. We bulk import your open inventory as part of go-live, so the whole back room is searchable on day one and nobody has to log it twice.
How is Boomerang priced?
An annual platform subscription sized to your venues and volume, with every new feature included as it ships. Guests pay fair shipping. Boomerang offers multiple revenue-share opportunities, and partners on average earn back upwards of 25% of their annual contract value every year. Book a demo and we will scope it with you.
