You tap your pen. Your knee bounces. You think better while pacing. If that’s you, you already know that sitting perfectly still is not your best focus position. For many people with ADHD, a bit of extra sensory input makes attention easier, not harder.
Why some brains want more input
There is a growing body of research suggesting that, for people with ADHD, movement isn’t just restlessness; it may be part of how attention gets regulated.
In a 2016 study at the University of California, children aged 10 to 17 wore motion sensors on their ankles while doing an attention task. In the ADHD group, more intense movement was linked with better accuracy on individual trials. In typically developing children, movement made no difference.
This fits with the idea behind background noise for ADHD: that some brains work best with a little more stimulation than a quiet, still environment provides. Sound adds stimulation through the ears. Movement and touch add it through the body.
What haptic sync is
Haptics are the small, precise vibrations your iPhone uses for taps and alerts. Synced haptics vibrate in time with audio, so you feel a gentle pulse that follows the rhythm or texture of the sound.
It’s a subtle effect. Think of a cat purring on your lap rather than a phone ringing. The idea isn’t to wake you up but to give your attention a second, steady channel to rest on.
How people use it
During focus blocks: the phone rests on the desk or in a pocket, adding a faint pulse under brown noise or a beta preset.
When thoughts race: some people hold the phone during a slow theta or alpha session and focus on the rhythm.
For winding down: gentler patterns in Sleep mode, for people who find them calming rather than stimulating.
It’s personal. Some people love the extra anchor. Others find any vibration distracting. Try it for a few sessions before deciding.
Other ways to add sensory input
Haptics are one tool among many. If touch helps you, these may too:
A fidget toy or textured object in your non-writing hand.
Choose a Haptic Mode: Focus for daytime, Sleep for gentler bedtime patterns, or Balanced.
Play any sound. Each solfeggio tone has its own vibration pattern.
In Solbox
Haptic sync is optional and works with every sound in Solbox: noise colors, soundscapes, binaural beats and solfeggio tones. Pair it with a Pomodoro timer for focus, or a fade-out sleep timer at night.
Frequently asked questions
What is haptic sync in Solbox?
It's an optional setting that makes your iPhone vibrate gently in time with the audio you're playing. Each solfeggio tone has its own vibration pattern, and you can choose Sleep, Focus or Balanced modes.
Why do I fidget when I'm trying to concentrate?
For many people with ADHD, movement seems to help regulate attention. Research has found that more movement during attention tasks was linked with better performance in children with ADHD.
Will vibrations keep me awake at night?
They can for some people. Sleep mode uses gentler patterns, but if you find any vibration stimulating, turn haptics off for bedtime and keep them for daytime focus.
Do haptics drain the battery?
They use a little extra power, like any vibration. For long sleep sessions, keep your phone on charge or switch haptics off.
