Underfoot

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 ⢠Appalachian Trail - 3,478 km, Georgia to Maine, 18 sections. Free, all of it. ⢠Pacific Crest Trail - 4,269 km, desert to the North Cascades, 20 sections. ⢠Route 66 - 3,643 km, Chicago to the Pacific, 20 sections. ⢠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).

Verdict
The clearest difference is in-app purchases: RIVL Run at none against Underfoot's 3. RIVL Run also leads on update cadence (daily vs every 4 days) and iOS requirement (18.4 vs 26.0). On price, ads and device support there is nothing between them.
