Activate Your FOCI

  • Plug in your FOCI to charge with the charging cable provided to activate your FOCI.
  • Your FOCI will show a blue light, and will vibrate twice to show it is activated.
  • Pair your FOCI within 30 mins from activation, otherwise you will need to plug in again to reactivate.

Sign Up and Pair Your FOCI

  • Make sure the bluetooth is turned on in your smartphone, but do not pair FOCI in your bluetooth settings.
  • Open the FOCI app, and follow the steps to create an account.
  • The app will now search for your device, place your FOCI next to your smartphone.
  • When your device name appears, you can press the name to pair your FOCI.


  • If you accidentally pair your FOCI through bluetooth settings, you need to reset bluetooth devices. While inside the app, turn on and then off airplane mode in the slide-down settings from the top of the screen.


2. Using FOCI

We have composed a blog post for details on FOCI’s learning and how to wear FOCI in order to improve the strength of the signal.

How to wear FOCI

Clip FOCI to your waistline, with the clip facing outwards, to start tracking. FOCI is designed for desk work, use it when you are seated to give FOCI a good signal.

There are a couple of ways you can improve FOCI’s signal:

  • While direct skin contact is not necessary, keeping minimal layers of clothing between FOCI and your skin will dramatically improve signal.
  • If you wear FOCI on an elastic or well-fitted waistline rather than loose or non-elastic pants, breathing signals are generally much stronger.

Haptic feedback

When you leave focus or flow, FOCI lets you know you have done well and reminds you to refocus with a gentle vibration at your waist.

Water Resistance with Caution

  • FOCI is designed to be water resistant, to sustain user incidents such as accidentally putting it in washing-machine or dropping it into basin. However, we strongly advise you not to intentionally immerse FOCI, as this may reduce FOCI’s water resistance lifespan.
  • If you accidentally drop FOCI in water, take it out and leave it to dry for 48 hours before charging, otherwise it may cause a short-circuit.


3. Inside The App

Real Time Cognitive States

  • You can see your cognitive state in real time as a fluid orb that moves with your breath.
  • The states that FOCI tracks are Focus, Calm, Distracted (Not in Focus), Fatigue, Stress, and Flow. You can also check out our website for an illustration of the different states: https://fociai.com/pages/cognitive-biometrics

There are also a few phrases you will see:

  • Learning in progress, % complete: This means FOCI is still learning your personal characteristics. In general FOCI  takes around 2-3 days of learning to personalize to you.
  • Adapting to breathing: This means FOCI has detected some changes in your breathing patterns and is recalibrating.
  • In motion: This means there is too much motion noise for FOCI to accurately infer your cognitive states from your diaphragmatic breathing signals.


You can see your day recorded as mind orbs of different cognitive states, and compare your time spent in deep focus over time.

  • Today’s states: by default, this page shows you all the streaks that you have formed throughout the day. Press the orbs to view the streak name, streak length, and when you left the streak.
  • Past states: you can go through the calendar and view all your past days states, from when you started using FOCI.
  • Deep Focus: a summary tracking your cumulative deep focus, compared to yesterday, this time last week, your weekly best, and your all time best.

Battery life

One charge is designed to last 7 days under typical usage. You can find the battery level via settings > device > Battery Remaining, so long as FOCI has some battery remaining and is connected to the app.
