Chapter Five: Radical Redesign · 12–16 August 2026
Stop arguing about who's going where.
Everyone in your crew stars the sets they want. Swap one QR code. BoomSched folds the lot into a single timeline — what you're all doing together, who's wandering off, and exactly where you'd lose each other.
How the merge works
No accounts. No sign-up. No server that can fall over at the exact moment you need it.
Star your sets
Browse the timetable and tap the sets you want. Your picks build into a day-by-day schedule with clash warnings and the gaps in between.
Swap a code
Your picks compress into a QR code. Your mate points their phone at it and the two schedules merge on the spot — no signal required.
See the crew
One merged timeline: unanimous picks, who's going to what, and the splits where half of you are heading to a different stage.
Built for a field, not a wifi cafe
Boomtown is 66,000 people in a valley near Winchester. Mobile data there is a rumour. So the crew feature doesn't depend on it.
Works fully offline
Your picks encode into a ~350-character payload carried by a QR code. Decoding and merging both happen on the phone. Nothing needs to reach a server.
Survives app updates
Sets are identified by a content hash rather than a position in a list, so a mate on an older build can still share with you. Anything unknown is skipped with a visible count, never quietly mapped to the wrong artist.
Right time, any phone
Times are stored as festival wall clocks, so 22:00 reads as 22:00 whatever your phone's timezone — and Friday's 2am set stays on Friday's programme.
About the times
Boomtown publishes start times only. Finish times here are worked out from the next set on the same stage, capped at two hours, and anything resting on that estimate is labelled “possible” rather than stated as fact. 9 announced venues don't have times out yet — they're listed as such rather than given invented ones.
