Quests on top of the map
RLQuest gives you a few outdoor quests every morning, checks that you did them, and fills in your map as you go. For iPhone and Android.
Fog of World has been on the App Store since 2012, and it does one thing with real care: it records where you've been and lifts the fog from those parts of the map. If you've searched for an alternative, it's probably not because it does that badly. More likely you want something to happen on the map besides the fog thinning.
This page gives Fog of World its due, then explains where RLQuest goes a different way. It isn't a ranking, and it deliberately leaves out prices and store privacy labels. The two apps set out to answer different questions.
Fog of World, by Ollix, describes itself on the App Store as a real-life travel and exploring game where you need to remove the fog on the map. In practice it is a movement tracker with a fog-of-war layer: as you move, your route clears the fog, and over years the cleared area becomes a record of everywhere you've physically been. It reports how much of each continent and country you've uncovered, includes a track editor, and imports GPX and KML files, so old hiking logs and past trips can be added.
It's available for iPhone and iPad and for Android. According to its store page, your data stays on your device, with syncing handled through your own cloud storage. The app is still actively maintained; the current version dates from May 2026. There are no quests, no daily tasks and no places to visit. That is a design choice, not an omission: Fog of World is a map of your life, and it stays out of the way.
Fog of World answers the question where have I been. RLQuest starts from a different one: what should I do outside today. Every morning it hands you three to ten quests from a library of more than 2,700, chosen to fit your age, interests, the weather, the season and the time you've said you have. Walk two kilometers and end up somewhere else. Photograph something mostly red. Be at a shoreline for sunset. Get to a castle, lighthouse or viewpoint you've never visited.
The app then checks what it can: the recorded route for a distance quest, the photo for a photo quest, the clock for an evening one, and it tells you plainly when it can't check something. RLQuest has a fog-style map as well, made of hexagon tiles about 350 meters across that fill in as you walk, and it works offline. But the map is a by-product of the quests rather than the whole point. On top of it sit real places pulled from OpenStreetMap, more than 1.5 million across Europe and North America, first finds for being the first RLQuest player to complete a quest somewhere, and 213 achievements in 69 series.
| Fog of World | RLQuest | |
|---|---|---|
| What it is | A long-running movement tracker with a fog-of-war map | A daily quest app with a hexagon map that fills in as you walk |
| How you play | Open it, move, watch the fog clear; import past tracks | Get 3 to 10 quests each morning, go and do them, the app checks |
| What it asks of you | Let it record your movement; nothing else | Actually do the quest: the route, photo, steps or clock have to match |
| The map | Precise trails, exploration percentages by continent and country, track editor | Tiles around 350 m across, real places on top, first finds, offline |
| What's on the map besides you | Nothing; it's your record | Castles, lighthouses, viewpoints and ruins from OpenStreetMap |
| Platforms | iPhone, iPad, Android | iPhone, Android |
Fog of World suits people who want a complete, precise, lifelong record of where they've been, who travel, and who'd like to import a decade of GPX files so the record starts before the download. It rewards patience over years, and it doesn't nag.
RLQuest suits people who want a reason to go out today, mostly near home, and who like being handed a task and having it checked. Its map is coarser by design, hexagons rather than trails, and it won't import your past. Some people will want both: one for the record, one for the nudge.
Prices differ by store and country, and the stores' data labels are declarations by developers, so neither is compared here. Check the current store pages for both apps before you decide.
