Overview

Flanra is an audio guide app for walking tours. Guides and local enthusiasts record city tours in their own voice, and you walk them at your own pace, with a map from stop to stop. I took it from the first product documents to a build on Google Play: the idea, the name and logo, every screen, the code with Claude Code, the store graphics and the landing page.

The problem

A live guide is great until you stand at the back of the group on a noisy street. Museum audio guides mean queues for rented hardware. Every place has its own app that you install for one visit. And the AI tour apps read generated text in a synthetic voice, so the personality and the local knowledge are gone. Guides have their own problem: their knowledge only earns while they are physically walking a group around.

  • A listener on a walk has busy eyes, so the important things must work without looking at the screen
  • User-made tours usually look amateur: crooked photos and mismatched covers
  • A listener's app and a guide's tool need different pace, permissions and notifications

The solution

I took a model people already know from their phones: a tour is an album, a stop is a track, a guide is the artist. Every tour gets its own colour and line mark like a metro line, so the catalogue looks like one system even when the author is an amateur. The map stays muted, and only the tour and its stops have colour.

  • Flanra for listening and Flanra Studio for guides, two products on one account
  • Each stop plays on its own when you arrive, with the phone in your pocket
  • Works offline, and the text follows the voice
  • A person reviews every guide and listens to tours before they reach listeners

Flanra is in an internal test on Google Play, with the landing page ready for launch. The first tours are set in Gdańsk, and guides can apply through Flanra Studio.

  • One visual system for every tour, whoever records it
  • A guide's path from application to publishing on their own after three tours
  • A working demo that needs no accounts or backend
