## What is RunForm?

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.
