Service Overview Topo is a completely new 'city information app' where 'things happening nearby' flow as cards simply by moving the map. Posted cards are published within a 500-meter radius for 3 days and naturally disappear over time, allowing users to obtain real-time information that is valuable exactly because it is 'now'. Furthermore, utilizing on-device AI technology enables 4-tap posting without text typing, allowing even those who 'only read SNS' to casually share the city's 'now'.

'Topo ─ Nearby Information Stream' allows you to casually post and view the city's 'now'.

Topo is new. Its 4 features:

1) The 'now' of your location flows in Just by opening Topo, the 'now' around you flows in. By further moving the map, you can easily check information from various places. Because you can post text with photos in 4 taps, anyone can become an observer of the city.

2) Disappears in 3 days. It becomes special because you can only see it now Posts disappear after 3 days and are not kept permanently, which gives special value to the information of that exact moment. Real-time information spreads across the city, shaping a new 'now' of the city through Topo.

3) The more you contribute, the deeper your connection with the city Through the user rank system, disseminating information raises your rank, eventually giving you the chance to become a 'Guardian of the City'. This system is designed not for competition, but for nurturing the city together.

4) Topo's Town Forecast —— As a new city media Topo operates 'Topo's Town Forecast', which distributes the 'city's condition' of 8 cities nationwide daily, providing a forecast summarizing the 'mood and condition' of that city.

Such changes in the city are accumulated and analyzed daily within Topo. As a new regional media business going beyond the framework of an application, it provides a content experience connecting the city and people. Forecasts for each city can also be viewed for free on the Web.
