Runners Toolbox

Everything you need to plan and review your runs – in one app, without an account, without ads and without internet. Your data stays on your phone. Choose how you run – road, track or trail – and the app puts the right tools up front. All of them are always there. THE TOOLS • Pace calculator: pace, time, distance and speed – enter two, get the third. • Split planner: splits for an even pace, a negative or a positive split – with a printable pace band for your wrist. • Race prediction: how fast are you over other distances? Based on the proven Riegel formula. • Event planner: your races with countdown, taper tips, packing list, reminders and race strategy. • Elevation & GPX: open a route from Komoot, Strava or your watch, see the climbs and get a pace plan per kilometer at an even effort. • Heart rate zones: your training zones from maximum heart rate, heart rate reserve or lactate threshold. • VO₂max estimate: from a race time – or take over the value from your watch. • Age grading: how good is your time for your age? Road after the 2025 standards, track after the WMA 2023 factors. • Track calculator: lap times and finish times on 400 m tracks, also in the outer lanes. • Interval planner with timer: build a session and run it with sounds, vibration and voice cues – also with the screen off. • Cadence metronome: hear the beat for your step rate, also in the background. • Treadmill converter: turn treadmill speed and incline into outdoor pace and back. • Heat adjustment: how much slower to plan in heat and humidity. • Fueling: carbs per hour, gel plan and drinking from your sweat rate. • Shoe tracker: count the kilometers per pair and think of new shoes in time. ALSO • Your runner card shows your latest results at a glance – with your own photo if you like. • Home screen widgets: runner card, single value, quick start and race countdown. • Your own distances, like your home loop, as quick picks. • Values from one tool are offered in the next – never required. • Kilometers or miles, light or dark, English or German. TRANSPARENT Every tool names the formula or study it is based on. All results are estimates and no medical advice. PRIVACY No sign-up, no ads, no analytics, no internet access. What you enter stays in the app on your device.
