Fog-of-war map with loop capture
Every GPS activity can reveal fog along the route, and closed loops can capture the area inside the loop. This gives the map a sense of real-world progress rather than just a track log.
Kraina
Kraina is a fog-of-war map for runs, rides, and hikes that turns GPS activity into a private exploration atlas. It supports Strava, Wahoo, and GPX imports, with privacy-first modes like Rolling Fog, Heartland, and Private Zones.
Overview
Kraina is a fog-of-war map for runs, rides, and hikes. It turns GPS activity into a private exploration atlas where every route can reveal new territory, closed loops can capture area, and repeated visits can keep routes alive under rolling visibility rules.
The product is built around privacy-first tracking and recurring motivation. Users can start on iPhone or web, connect Strava or Wahoo, upload GPX files, and use modes such as Classic, Rolling Fog, and Heartland to shape how their map evolves over time.
Core features
Time-based map upkeep
Rolling Fog keeps older areas visible only while they stay within the chosen time window. Free accounts use 90 days; Supporter accounts can choose 180 or 365 days for a longer upkeep cycle.
Heartland core area
Heartland highlights your most visited core area based on movement over a rolling window. It helps surface the places you return to most often instead of only the newest routes.
Weekly exploration prompts
Weekly Missions create three circular exploration prompts every Monday around your Heartland. They are designed to nudge regular outings in new directions without relying on exact pin targets.
Generated expedition challenges
Expeditions let Supporter users generate self-directed multi-step challenges with circular outposts and corridor boost rewards. The site describes them as a way to build longer exploration loops.
Private-first workflow and sharing
Kraina supports Google or magic-link sign-in, Strava and Wahoo connections, GPX upload, Private Zones, and share cards that avoid exposing precise home locations.
Common ways people use Kraina
Build a personal exploration map
Track regular runs or rides and watch familiar streets or trails become visible as you revisit them. This fits people who want a personal map that reflects actual movement instead of a static activity log.
Maintain an area through repeat visits
Use Rolling Fog if you want routes to stay visible only when you return to them periodically. It works as a habit loop for people who want their map to reward consistency.
Add lightweight exploration goals
Follow Weekly Missions or Expeditions when you want structured reasons to explore new areas. These prompts are useful for adding variety to routine outings without turning the app into a live navigation tool.
Consolidate historical activity data
Import Strava, Wahoo, or GPX history to backfill older activities and gradually reveal past routes. This is useful when you already have months or years of GPS activity elsewhere and want to see it as one atlas.
Keep exploration private
Use Private Zones and private-by-default sharing when you want to keep sensitive locations from being exposed. The product also supports share cards that show milestones without revealing an exact home location.
Pros and Cons
Pros
- Turns outdoor activities into a map that reveals fog along actual GPS tracks.
- Offers multiple exploration modes, including Classic, Rolling Fog, and Heartland.
- Supports Strava, Wahoo, and GPX upload, which covers both connected accounts and manual imports.
- Keeps maps private by default and includes Private Zones for sensitive areas.
- Provides recurring prompts through Weekly Missions and optional Expedition challenges.
Cons
- Free accounts are limited to the 90-day Rolling Fog window and a total of 150 historical activities for backfill.
- The map only changes when an activity includes usable real-world GPS coordinates, so indoor, treadmill, and many virtual activities will not affect it.
- Some features, including longer Rolling Fog windows and Expeditions, are Supporter-only.
FAQ
How do I get started with Kraina?
You sign in with Google or a magic link, then connect Strava, Wahoo, or upload a GPX file. After that, sync runs in the background and your historical activities are imported gradually through backfill.
Which activity sources can Kraina use?
Kraina currently supports Strava, Wahoo, and manual GPX upload. The site says more platforms may be added later, depending on vendor developer programs and rules.
What kinds of activities change the map?
Activities with a real-world GPS track affect the map, including outdoor runs, outdoor rides, hikes, and walks. Indoor, treadmill, or virtual activities generally do not reveal fog because they do not provide usable route geometry.
What changes in the Supporter plan?
Free accounts use a 90-day Rolling Fog window. Supporter accounts can use 90-, 180-, or 365-day windows, and also get Endpoint Caps, Individual Expeditions, and faster handling for heavy sync and rebuild jobs.
How does Kraina handle privacy?
Kraina is private by default, and you can export or delete your data anytime. Private Zones help with map logic near sensitive start or end points without making your address public.
