Why stand on nails
A few minutes on the nails, and your head goes quiet.
Your mind stops racing
The feeling underfoot is so strong that the noise in your head fades by itself. No need to try to “clear your mind”.
Breathe instead of flinching
At first everything says “step off”. Slow exhales keep you there, and that calm breathing stays with you off the board too.
Proof, not promises
Rate how you feel before and after each practice. In two weeks you'll have your own numbers, not someone else's claims.
How it works
Your sadhu board practice in three steps
-
01
Note how you feel
Rate your tension and energy from 1 to 10. Five seconds now gives you something to compare with later.
-
02
Step on when you're ready
A short countdown lets you step on calmly, then the timer starts. Breathing guide, bell and voice are optional. Stopped by accident? One tap undoes it.
-
03
See what changed
Your streak, record and time on the board, and above all how your tension shifts after every practice.
Minute by minute
What standing on nails feels like
First seconds
The sharp feeling is just your feet meeting the nails. Keep your knees soft and breathe out longer than you breathe in.
The hardest part
This is often the peak. Keep breathing; it usually passes.
Getting used to it
Your body starts to get used to it. You may feel warmth; just notice it.
Getting easier
Don't fight the sensations. Trembling, laughter or tears are normal.
Sharpness fades
For many people the sharpness fades somewhere between minutes 5 and 10. Just stay with it.
Stillness
Calm breathing. When you're ready, step off slowly.
A typical pattern, not a promise: everyone's pace is different. The app shows the same tips right on the timer.
The effect
Calm you can measure
Sadharo compares how you feel before and after every practice and shows the average shift. Here's what a report looks like after a month.

Depth
10 to 20 minutes, silence, and a firmer board when you're ready. For those who already stand calmly for 10 minutes.
Goals tuned to your board
The closer the nails, the softer it feels: your weight spreads over more points. Pick your board's spacing and your weight.
The all-round choice for most beginners.

Technique lessons
Seven short animated lessons: getting ready, starting seated, stepping on and off, shifting your weight, breathing, lying on the board.

FAQ
Common questions about sadhu board practice
Which sadhu board do I need?
Any sadhu board or nail board works, bought or homemade. Enter your nail spacing and the goals adjust to it.
How long should I stand on a sadhu board the first time?
One minute, sitting on a chair. The free First 21 Days program then takes you to standing, without rushing: time grows only as you get comfortable.
Does standing on a sadhu board hurt?
At first, yes: the first seconds feel sharp, then it eases. The “Scared?” button on the timer helps with breathing and counting. If you feel sharp pain, numbness or dizziness, step off at once.
Does my data go anywhere?
Without signing in, everything stays on your phone. If you sign in with Apple or Google, a copy is kept in the cloud so you can move it to a new phone. In a challenge, friends see your name, your photo if you set one and the days you practiced; they see your minutes or practice details only if you choose to share them. You can report or block a member, and delete your account right in the app.
Is there a sadhu board app for iPhone and Android?
Yes, and on watches: Apple Watch and Wear OS. Your history can move between platforms.
Why not just use a regular timer?
A regular timer doesn't know you're on nails. Sadharo gives you a countdown to step on calmly, sets goals for your board's spacing, lets you undo an accidental stop and shows how you feel afterwards.
The first minute is the longest. It gets easier.
The First 21 Days program is free, no sign-up needed. Download Sadharo and start today.
