Koshio

Read full description

Koshio turns your run into a game of territory. Start a run, go around a block, a park or a whole neighbourhood, and come back to where you started. The moment you close the loop, everything inside it turns your colour on the map. Run over someone else's territory and you take it from them. Then they can come and take it back. HOW IT WORKS 1. Start a run. The map follows your route live. 2. Close the loop. Return to your starting point and the area inside becomes yours. 3. Defend it. Your territory stays on the map until another runner claims it. RUN WITH A CLUB Start a club or join one. Clubs have their own announcement board, their own events and their own member rankings. Organise a run, see who says they are coming, and check them in on the day with the attendance table. KNOW WHERE YOU STAND You have a rank in every city you run in, and a rank in your country. Territory helps, but every run counts towards your score even when you claim nothing. IN THE APP - Live map showing who owns what, and how big it is - Clubs, events and an attendance table - City and country leaderboards - Friends, so you can filter the map to just the people you know - Notifications when your territory is taken, when someone mentions you, and before an event starts - Run history with route, distance, time and calories, and charts of your progress - Cheat protection: every run is checked on the server against speed, distance and movement data, so nobody claims a neighbourhood from a car - Turkish, English and German BACKGROUND LOCATION Koshio needs your location while a run is recording, including when your screen is off or you switch to another app, because the loop has to be tracked without gaps. Continued use of GPS in the background can shorten battery life. Location is only recorded while a run is active, and you can stop it at any time. Koshio is for running outdoors. Watch the traffic, watch your footing, and never enter somewhere unsafe just to claim it. info@koshio.app

Your steps already add up to something. This app decides what. Underfoot turns the steps your phone already counts into distance along a real long-distance route: the actual surveyed line, with its actual length, its actual climbs and its actual places. Walk your usual day, and you move a little further down the trail. FOUR ROUTES, ALL ON YOUR PHONE โ€ข Appalachian Trail - 3,478 km, Georgia to Maine, 18 sections. Free, all of it. โ€ข Pacific Crest Trail - 4,269 km, desert to the North Cascades, 20 sections. โ€ข Route 66 - 3,643 km, Chicago to the Pacific, 20 sections. โ€ข Camino de Santiago - 762 km across northern Spain, 7 sections. Nothing is downloaded later. Every route is in the app from the first launch, and it all works in airplane mode. PAINTED, NOT PHOTOGRAPHED 128 original paintings, one for every stretch of country you walk through, in daylight and at night. The season is baked into each one, so a year passes while you walk: early spring in Georgia, high summer in Virginia, late autumn at the end. A JOURNAL THAT BECOMES A BOOK One line a day, in your words. Along the way you pass named places: shelters with the year they were built, passes, towns, roadside stops, and find what somebody walking before you wrote there. After a year you have something you won't want to lose. SECTIONS, NOT ONE ENDLESS LINE A long trail takes years at an honest pace, so the unit that matters is the section: a month or two, ending in something. Eighteen of them on the Appalachian Trail alone. NO STREAKS, NO GUILT A day without walking is called a zero day, and on a real trail it is completely normal. Nothing here burns down, nothing scolds you, nothing asks you to come back tomorrow or lose what you built. NOTHING LEAVES YOUR DEVICE No account, no server, no analytics, no third-party code of any kind. Your steps are read from Health on your phone and stay there. Progress syncs between your own devices through your private iCloud, and nowhere else. WIDGETS One for each trail you're walking, in four sizes, including the Lock Screen. FREE AND PRO The Appalachian Trail is free in full: every section, every painting, the journal, the widget. Pro opens the rest of the catalogue, lets you walk several routes at once, writes fresh journal entries on your device, and exports your journal as a book. For motivation, not for navigation. This is not a hiking navigation app and carries no GPS guidance of any kind. Route data comes from public surveys and is credited in the app. Not affiliated with or endorsed by the Appalachian Trail Conservancy, the Pacific Crest Trail Association, or the National Park Service. SUBSCRIPTION DETAILS Underfoot Pro is offered as a monthly subscription (US$4.99 per month) and a yearly subscription (US$29.99 per year). Lifetime (US$59.99) is a one-time purchase, not a subscription. Prices are in US dollars and may differ in other regions. Payment is charged to your Apple Account at confirmation of purchase.
