Kalymnos topoguide is a digital field guide for hiking and tourism in Kalymnos Island. The app is the result of a join venture of AnaDigit and the alternative tourism company Alternet-Greece.

It includes routes, descriptions and photos for 16 hiking trails and 4 bike rides. Each trail has an elevation profile, a statistic analysis, a detailed description, several photos and a POIs list.

Kalymnos is famous worldwide for its endless climbing terrains and the almost 3000 routes it offers. Kalymnos topoguide provides a list of the climbing sectors and information and maps for their approach.

The application offers detailed off-line maps and an extensive introduction on geography, geology, the most important settlements and monuments, and the nature of Kalymnos Island. The app offers also a useful list of POIs (most island's accommodations are included) with a comprehensive search engine.

In the field, the application identifies the nearest route and make active navigation to it and then along it, with continuous messages to the user, while pops-up photos on every interesting or important terrain feature close to his position. If the hiker position is more than 20 meters far from the trail, the application warns him and suggests how to go back.

The cartographic company AnaDigit, creator of the application, has issued hundreds of hiking maps for Greece (eg. maps of Kalymnos,Santorini, Crete, Mt. Olympus, Zagori, Sifnos, Naxos and other Aegean islands). To build the application and ensuring data accuracy, all tracks and cartographic information have been recorded during July 2016.
