HeckNo Practise getting away. At home, with your phone as coach.
HeckNo watches how you move through your phone’s camera and tells you what to fix: your guard, your strikes, getting up from the ground. Nothing is recorded, and there’s no account.
7 days free, then €29.99 a year.
Lessons and shout drills are always free.
See it early
Read a situation before it turns.
Say it loud
Use your voice with force.
Strike to get free
Palm, elbow, knee and more, coached on camera.
Get away
Make room, then leave.
A coach that watches you move.
Prop your phone up and step back. The camera follows your joints and checks each rep: is the arm straight at the hit, is the other hand guarding your face, how fast you come back to guard.
- Arm straight at the hit
- Back to guard in 0.4 s
- Rear hand dropped: keep it by your chin
The video is read on your phone and never stored or sent.
A new combo, from a real situation.
Each day brings a combo built for you from 500 short situations: at a bus stop, in a car park, at work. How close he is decides the strikes, and the combos get longer and faster as your moves get cleaner.
Every combo ends with you getting away.
Starts where you are.
Three quick movement games set your level. Strikes open when your body is ready for them, kicks after that. Nine units take you from reading a situation to getting up from the ground, and every week you see what moved.
Most of what works isn’t physical. So the app teaches that too.

Leaving early: the skill women actually used
Noticing early and leaving early are what graduates actually used.
GrabsGrabs and hands on the neck: what everyone should know
No marks means nothing — about half have none. Say “strangled” when you go.

It is the most common reaction, and it is involuntary.
Questions people ask.
Can you really learn self-defence from an app?
You can learn and practise the moves, your voice and the decisions that matter most, and the camera tells you what to fix. What an app can’t give you is a partner. HeckNo says clearly which drills need one before they become a skill.
Is my camera video recorded or uploaded?
No. The camera and microphone are read live on your phone, to follow your movement and to measure a shout. Nothing is saved, sent or shown to anyone, and there is no account.
I’m not fit. Can I still start?
Yes. Three quick movement games set your level. If you are starting from a low base, ten-minute body prep sessions come first, and strikes open when your body is ready for them.
Who is it for?
Women aged 16 and over who want to practise what matters most: noticing early, using their voice, getting free and getting away. Sixteen- and seventeen-year-olds get a teen version of the course.
How does the free week work?
The yearly plan starts with 7 days free. Nothing is charged until day 7, the app reminds you on day 5, and you can cancel any time in your App Store settings. Lessons and shout drills stay free either way.
Is it available on Android?
Not yet. HeckNo is on iPhone first.
