What's your Everesting? Everesting started as the simplest and hardest idea in endurance sport: climb enough elevation, in a single effort, to match the height of Everest. 8,848 metres. One attempt. No shortcuts. That philosophy hasn't changed. But we believe everyone has their own Everesting: the elevation challenge that sits just beyond your limit, demands honest effort, and changes you in the process. The Everesting app is built for every athlete who moves upward: cyclists, runners, hikers, stair climbers, skiers and beyond. It doesn't matter what sport you do or how high your mountain is. What matters is that the effort is honest. ELEVATION CHALLENGES Take on structured elevation challenges designed for all levels and all sports. Each challenge has a target, a timeframe, and a global community of athletes doing it alongside you. ELEVATION INDEX Your Index is a single score built from your all-time elevation activity. It doesn't reset. It doesn't lie. Every metre you've honestly earned is in there, and it grows every time you go up. ELEVATION RANKING A 12-month rolling leaderboard built on real elevation data. Your position reflects the last year of genuine effort. Keep climbing to hold your place. Stop, and the ranking moves without you. FOR EVERY KIND OF ATHLETE Cycling, running, hiking, and more. The app connects to your Strava profile or your existing fitness platforms so your elevation data is already waiting for you. A GLOBAL COMMUNITY Everesting challenges have been completed by +20k athletes in 124 countries. The app brings that community together: the finishers, the first-timers, and everyone in between.

The clearest difference is in-app purchases: FLOWBIO at none against Everesting's 3. Everesting's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.0). On price, update cadence and ads there is nothing between them.
