Read full description

Stop guessing. Start understanding your running form. Why do some runs feel effortless and others don't? RunForm reveals the two things that actually explain it — no charts to decode, no data overload. Just two clear numbers that show whether you're getting fitter and running smoother: – Heart4Speed – This is our running engine (heart) efficiency. Heart4Speed shows how much speed you generate for every heartbeat. It combines aerobic fitness and running economy into a single, easy-to-understand number. – Track fitness improvements over time – See how efficiently your body converts effort into movement In simple terms: are you getting more out of every beat of your heart? – SmoothOperator – This is your running smoothness and movement efficiency. Every step you take sends energy in two directions: forward (useful) and upward (wasted). SmoothOperator measures how much of that energy actually drives you forward. – Improve running form and reduce wasted energy – Run smoother, not harder It’s a direct view into how efficiently you move with every stride. Built for real runners. RunForm is designed to make complex biomechanics simple and useful: – Clear, focused metrics you can trust – No clutter - just actionable insights – Track progress across runs and over time – Turn data into better running RunForm helps you answer the questions that matter: – Am I becoming more efficient? – Is my form improving? – Am I wasting energy as I fatigue? Works with your existing data. Connect with Apple Health and start analysing your runs instantly – no extra devices or setup required. RunForm doesn’t just track your runs. It helps you understand them – so you can improve with purpose.
