Get the app

Welcome down Independent festival app · iPhone & Android iPhone & Android

Yourweekend, uncut.

BASEMNT is the independent festival app: one app for every festival, club night and concert, instead of a new branded app for each. Your artists and genres come with you, every event looks the way you already know, and your crew stays on one plan.

One app for every event

The plan, the crew, and the day itself.

  1. § 01

    The plan

    Lineups, stages, set times, maps and weather for festivals, club nights and concerts. Mark your days, pick your sets.

  2. § 02

    The crew

    One crew timetable, chat with polls and locker codes, shared files, a view of when everyone is free — and location sharing only when you choose to.

  3. § 03

    The day

    Set reminders, a lock-screen Live Activity, rain and thunder heads-ups, and an offline pack for when the network gives up.

  4. § 04

    The stamps

    Every festival you go to gets its own stamp in your Passport, in that festival’s colours. After the weekend, play your recap — the sets you saw, how far you danced, and who in your crew danced hardest.

§ 01 Discover

Find yournext.

Let FOR YOU line up what fits your taste, browse by genre, country and date, or open the map to see what is on near you. Every festival page carries the lineup, stages, timetable, map and weather — mark the days you are going and it is all yours, on your phone.

  • FOR YOU picks tuned to your genres and artists
  • Lineup, stages, timetable, map and weather on one page
  • Missing an event? Suggest it in the app and get told when it is verified

§ 02 Timetable

Your sets.Your call.

Follow the artists you listen to — by hand or from Apple Music — and BASEMNT suggests their sets on the timetable. Make the ones you want yours and they become your schedule, with a reminder before each one starts.

  • Suggested from your music, one tap to make it yours
  • Overlapping picks shown side by side, so you can choose
  • Wrong set time? Fix it for everyone, with history and undo

§ 03 Crew

One crew.One plan.

Create a crew or join with a link, code or QR. Everyone’s picks land on one crew timetable, so you know who is where before the day starts, and when you are all free. Chat with polls, timers and locker codes, keep files together, and find each other on the crew map — only if you switch sharing on.

  • Crew timetable with everyone’s picks side by side
  • Chat, polls, locker codes and shared files, also offline
  • Who danced hardest? Compare steps and km after the festival, if you share
  • Location sharing is off until you turn it on

§ 04 At the venue

On yourlock screen.

When you arrive, the Live Activity pins your next set, crew pings and festival updates to the lock screen and Dynamic Island, and keeps itself up to date. Set reminders and rain or thunder heads-ups arrive before you need them. Your plan stays on your phone when the network doesn’t.

§ 06 Passport

Every festival,stamped.

Mark a festival as Going and its stamp is already waiting on your Passport page. After the weekend it’s stamped — a visa, a postage stamp or a ticket in the festival’s own colours, with the days you were there. Pick the style you like; the foil ones you earn. Then play your recap: the sets you saw, how far you danced and recordings to listen back.

  • 01 Festivals attended
  • 02 Countries visited
  • 03 Days at festivals
  • 04 Kilometres danced

How it works

Get set up.

The same three steps the app walks you through on day one.

  1. § 01

    Bring your music

    Connect Apple Music or follow artists by hand. Their sets show up as suggestions on every timetable.

  2. § 02

    Pick your first festival

    Mark the days you are going. Lineup, stages, timetable, map and weather are ready — and download for offline on their own.

  3. § 03

    Rally your crew

    Create a crew and share the invite link. Everyone’s picks land on one timetable, with the crew chat built in.

FAQ

Questions.

§ 01 Which festivals are in BASEMNT?

Festivals, club nights and concerts, with lineups, stages and timetables from BASEMNT’s own data pipeline, organisers and the community, updated as set times are published. Missing something? Suggest it in the app: it shows up as a community listing straight away, and you are notified when the team has verified it.

§ 02 Why not use the festival’s own app?

A festival’s own app is built for that one event: you download it, set it up and learn it again for every weekend. BASEMNT is independent and works for every festival, club night and concert. Your artists and genres carry over, so the right sets are suggested straight away, and every lineup, timetable and map has the same layout. Organisers can publish their official information in BASEMNT, but none can pay to be shown higher.

§ 03 Does it work without signal?

Yes. For festivals you are going to, BASEMNT downloads an offline pack on Wi-Fi two days ahead: festival info, your timetable, maps, crew chats and files, and the weather. You can also start the download yourself.

§ 04 How does a crew work?

Create a crew and share the invite link, code or QR. Everyone’s picks show on one crew timetable, and you can see when everyone is free. Each crew has its own chat with polls, timers and locker codes, plus shared files. Location sharing is off unless you switch it on for a crew.

§ 05 Do I need to connect a music service?

No. Connecting Apple Music is optional — it only pre-fills the artists you follow, so their sets become suggestions. You can always search for and follow artists by hand. Spotify support is on its way.

§ 06 What is the Passport?

Your record of the festivals you go to. Mark a festival as Going and its stamp waits on your Passport page; after the weekend it’s stamped in the festival’s own colours, with the days you were there. You choose the style — visa, postage stamp or ticket — and earn foil ones along the way. The Passport also counts your festivals, countries, days and kilometres danced, and keeps a recap of the sets you saw.

§ 07 Is BASEMNT free?

Yes. BASEMNT is free to download on iPhone and Android and has no ads. Organisers can show promotions for their own events, but their marketing messages only reach you if you opt in.

§ 08 What happens with my data?

BASEMNT has no ads and doesn’t track you across apps. Location is used for the map, nearby events and any crew sharing you turn on. Steps and distance from Apple Health or Health Connect stay on your phone unless you choose to compare totals with friends, and Apple Watch sound levels never leave it. Usage statistics come in two tiers: basic counts with no identifier at all (on by default, with a switch) and detailed usage analytics tied to a random ID that isn’t connected to your account (off until you agree). Switching any of them off changes nothing about how the app works. The full story is in the privacy policy.

§ 09 Which phones and languages?

iPhone with iOS 16 or later, and Android 8.0 or later. The app is in English and Dutch, with more languages coming.
