Loisto products are traditional and trustworthy navigation software, well-known by boaters.

Taiste got the chance to develop the latest addition to their digital product family, Loisto Mariner. The app offers boaters and hikers an easy way to navigate. You can plan routes, identify other vessels around you and check the current weather forecast in the area.


    We designed new features to the app, which are aligned with the visual and functional trend of the product family.

Software Development

    We developed a native mobile app for both Android and iOS devices. The back end was written with Clojure. Data, such as weather forecasts and AIS data, was pulled from open data APIs.

Continuous Improvement

    We optimized various elements of app store listing to support our client's sales goals. Creating analytics events to acquire insights about user behavior was crucial as well.

Precise maps and comprehensive location search

The right destination and a route to get there are now easy to find. We developed an extremely comprehensive location search to Loisto Mariner, based on the location database of the National Land Survey of Finland.

The nautical charts and topographical maps of the app are precise and in vector format. What's more, the maps can also be used in offline mode.

Loisto Mariner - Clojure

The back end development tested our Clojure skills

The back end system of Loisto Mariner delivers up-to-date weather forecast, AIS data of the nearby vessels, as well as maps to be used in both online and offline modes. The back end was built with Clojure, our technology of choice in many of our recent projects.

Loisto Mariner - Maps

Weather forecast and guest harbors

We combined data from several APIs to make the app the smartest assistive software possible to boaters. The app shows an up-to-date weather forecast provided by the Finnish Meteorological Institute. In addition, Finnish guest harbors and their services are clearly marked on the map for added convenience.

Loistoi Mariner - AIS data

AIS data helps to identify other vessels

Big vessels present in the current area can be seen on the map in real-time. To make this possible, AIS data (Automatic Identification System), which helps to identify and locate other vessels, is pulled from Digitraffic's open API.
