First launch: iAF and your psychotype
When you connect the device for the first time, the application conducts calibration - determines your individual alpha frequency (iAF). This takes ~30 seconds with your eyes closed.
7–13 Hz scale and determination of psychotype. In the example - “Manager” (9.5 Hz)
iAF is a genetic “fingerprint” of the brain that determines your cognitive style:
| iAF range | Psychotype | Description |
|---|---|---|
| 7 – 9.5 Hz | Creator | Creative, imaginative thinking |
| 9.5 – 10.5 Hz | Manager / Entrepreneur | Management skills, analytics |
| 10.5 – 13 Hz | Engineer / Scientist | Technical, structural thinking |
iAF is a relatively stable indicator that characterizes your behavioral pattern
Home: statistics and iAPF
The main screen shows the dynamics of your iAPF (peak alpha frequency) - How far your current readings deviate from your average.

Monitoring: 3 real-time graphics
Chapter "Monitoring" - live brain panel. Simultaneously displayed 3 graphics, which you choose yourself.
Description of the “Monitoring” section and the main metrics in the application
Selecting 3 indicators for graphs
In monitoring settings, select any 3 of 6 available metrics:
Selection screen: check the required indicators
6 available metrics for charts
| Metrics | What does it show |
|---|---|
| Cognitive load | How busy is the brain with the current task? |
| Focus | Concentration on a specific object or task |
| Relaxation | A state of calm, without strong emotions |
| Self-control | Ability to suppress distractions |
| Excitement | Internal tension or growing excitement |
| Voltage | Emotions that make it difficult to calm down |
Scale 1 min: Load 63%, Focus 40%, Relaxation 46%
Scale 15 min: dynamics over a longer period
Recommended combinations of 3 charts
🎯 Combination 1: "Working mode"default
Cognitive load + Focus + Relaxation
Daily work, calls, tasks. Shows the balance of workload, concentration and rest. If the load is high and focus is falling, it’s time for a break.
🧠 Combination 2: “Antistress”
Relaxation + Tension + Self-control
Stressful situations, negotiations, conflicts. See in real time how tense you are and whether you can control yourself.
🎨 Combination 3: “Creative session”
Focus + Relaxation + Excitement
Brainstorming, creative tasks, idea generation. Balancing relaxation and focus is the key to a state of flow. Passion shows inner drive.
💻 Combination 4: “Deep Work”
Cognitive load + Focus + Self-control
Programming, analytics, writing texts. Self-control is more important than relaxation - it shows whether you can suppress distractions.
💤 Combination 5: “Recovery”
Relaxation + Tension + Cognitive load
Breaks, meditations, evening sessions. The goal is relaxation up, tension and load down.
Pie state diagram
In addition to 3 graphs, the application generates a general pie chart of the distribution of states per session:

Audio feedback
When tracking, you can configure sound signals that are triggered when thresholds are exceeded:
Upper threshold: sound, volume, delay
Lower threshold: Birds singing, Cat purring, Disturbing music, etc.
Sound logic:
- Upper threshold — triggers when the indicator higher set value (overload)
- Lower threshold — triggers when the indicator below norms (loss of focus)
- Volume and delay can be adjusted separately for each threshold
Fatigue and rest mode
The app tracks accumulated fatigue and signals when it's time to rest.
Setting Fatigue Thresholds
Moderate fatigue: 30%, Severe fatigue: 60%, Data buffer
| Parameter | Default | Description |
|---|---|---|
| Average fatigue | 30% | Transition from “weak” to “medium” |
| Extreme fatigue | 60% | Transition from "medium" to "strong" |
| Data Buffer | 10 Items | Smoothness of changes in indicators |
What does fatigue look like while trekking?
52% (Easy) - recommendation to rest for 2 minutes, current slot 10 minutes
Rest mode
Select duration (1–3 min)
Countdown timer. Deep rest = loud music
Rest Mode Settings
Melody, volume, frequency of notifications. If 0 - the function is disabled
Working day slots
The application automatically divides the working time into slots - periods between breaks:
1 slot per day (0h 10m). Slot 01: 12:51–13:01, 10 min, fatigue rate "Fast"
What slots give:
- See how long you can work until you get tired
- Determine your peak productivity hours
- Monitor whether breaks help you recover
- Create an individual work rhythm
