I built Liwa because concert research is a mess. It is a SwiftUI + Firestore iOS app that keeps the useful event-day details in one place.

Why I made it

Before a concert, you end up checking the venue site, Ticketmaster, transit pages, Reddit, social posts, and whatever comes up in search. Then you are still not sure if you can bring your bag or whether the train actually runs after the show.

I started with BTS at MetLife Stadium and focused on the questions that can make or break the day: what to bring, how to get there, what the weather is like, when to show up, and what is actually confirmed.

One rule I did not want to compromise on

If Liwa says something is allowed, it should be clear why it thinks that.

A venue can have a general rule, an artist can publish a one-off exception, and a fan can have useful but unverified information. I did not want to turn all of that into one confident-sounding answer. Liwa shows the source, keeps gaps visible, and lets official event guidance win when sources disagree.

How the policy logic works

• Event-specific official guidance beats the venue's general policy.
• Official venue guidance beats promoter, ticketing, or community information.
• Community reports can add context, but they cannot override an official source.
• “Not confirmed” is better than a guess.

What is in the app

Event dashboard

The show, venue, weather, and date-specific details at a glance.

Policy guidance and search

A practical answer to “can I bring this?”, with the source right there.

Getting there

Driving, rideshare, transit, accessibility, and the details that change on event day.

Amenities and merch

The little things you end up needing: charging, restrooms, will call, security, merch, and more.
