Guide24 — GPS Audio Guide for iOS and Android

Guide24 is a production mobile audio guide for exploring tourist routes across Ukraine.

Users select a route, start GPS navigation, and follow the path on an interactive map. When the user enters the configured radius of a location or direction point, the application automatically plays the corresponding audio content.

I worked on the complete product ecosystem, including the React Native mobile application, backend API, administration panel, integrations, analytics, and route-processing logic.

Key functionality:

- GPS navigation and route tracking;
- automatic audio playback based on geofencing;
- configurable points of interest and direction points;
- route deviation and speed warnings;
- offline audio caching;
- interactive map and compass;
- route completion and final fanfare;
- post-route questionnaires and feedback collection;
- voice assistant integration through Dialogflow;
- push notifications, Firebase Analytics, and Sentry;
- donations through Monobank;
- content and route management through an administration panel;
- integrations with Telegram, KeyCRM, and Google Forms.

Technology stack:

- React Native;
- Redux and NativeBase;
- Maps, GPS, compass, and audio playback;
- Firebase Analytics and push notifications;
- Sentry;
- Dialogflow and voice recognition;
- Laravel and laravel-admin;
- MySQL;
- Workerman;
- REST API.

The application was published in mobile stores and used by real visitors to navigate tourist routes.
