Question 1

How do I set up the sensor?

Accepted Answer

The sensor comes in two halves. Place one on each side of a flat resistance band — built-in magnets hold them together. Power on and pair with the Bandcizer app via Bluetooth. The sensor is ready to record.

Question 2

Which resistance bands work with the sensor?

Accepted Answer

Any flat resistance band. The sensor is calibrated for Theraband Latex Free bands (yellow through black), which are already standard in most Nordic physiotherapy clinics. Not compatible with tube bands, loop bands, fabric bands, or Theraband Silver and Gold (metal content disrupts the capacitive measurement).

Question 3

How does the patient log in to the app?

Accepted Answer

No email signup or password. The physiotherapist generates a QR code and 6-digit one-time code from the dashboard. The patient scans or enters the code. No password reset flows, no friction.

Question 4

What does the patient need?

Accepted Answer

A smartphone (iOS or Android) with Bluetooth enabled, the Bandcizer app, and a compatible flat resistance band. The sensor and return label are included in the shipment.

Question 5

What does the sensor actually measure?

Accepted Answer

The sensor uses capacitive measurement to detect band deformation — how much the resistance band stretches — at 20 times per second (20 Hz). This is a direct physical measurement, not motion tracking. It captures force output in Newtons, time under tension, rep quality, and session completion.

Question 6

How is this different from a wearable?

Accepted Answer

A wrist-worn accelerometer detects that the patient moved their arm. The Bandcizer sensor measures what the resistance band did. Different instrument, different data. Wearables measure body movement; Bandcizer measures exercise execution.

Question 7

What is the battery life?

Accepted Answer

40+ hours of active training time. Rechargeable via USB-C.

Question 8

What if the sensor breaks or stops working?

Accepted Answer

Hardware maintenance and replacement for normal wear is included in the subscription. If a sensor malfunctions, we replace it at no extra cost.

Question 9

What are the technical specifications?

Accepted Answer

Sampling rate: 20 Hz. Force range: 0–50 N. Battery: 40+ hours active, USB-C charging. Connectivity: Bluetooth Low Energy 4.0. Band compatibility: any flat resistance band (calibrated for Theraband Latex Free).

Question 10

What does the app show during a session?

Accepted Answer

Real-time tempo guidance — audio and visual cues that pace the patient through each phase of every rep (eccentric, isometric, concentric). The patient follows the rhythm. The sensor records what actually happened.

Question 11

What is the tempo guide?

Accepted Answer

The physiotherapist prescribes a tempo — e.g. 3-2-3 (three seconds eccentric, two seconds isometric, three seconds concentric). The app’s built-in metronome paces the patient through each phase with audio and visual cues. After the session, the sensor data shows whether the patient actually followed the prescribed tempo.

Question 12

Can patients message their physiotherapist through the app?

Accepted Answer

Yes. Patients can send messages directly from the app. The physiotherapist sees and responds from the dashboard. Every message is logged, timestamped, and scoped to the organisation.

Question 13

Is the app available on both iOS and Android?

Accepted Answer

The app supports both iOS and Android. iOS is currently available via TestFlight for pilot clinics, with App Store release coming soon. Android is planned. See the downloads page for the latest availability.

Question 14

What does the dashboard show?

Accepted Answer

Every patient’s training data: session history (when they trained, what exercises, detailed data), adherence (who trained this week, who didn’t), force progression (getting stronger or plateauing), and quality trends (improving execution or compensating). Data arrives automatically after each patient session.

Question 15

Can multiple staff members access the dashboard?

Accepted Answer

Yes. Add your entire team. There are no per-practitioner fees. One price per sensor — everyone on the team gets full dashboard access.

Question 16

How does patient data arrive in the dashboard?

Accepted Answer

Automatically. When the patient’s phone has connectivity after a session, the data syncs to the dashboard. No manual entry. No waiting for the next appointment.

Question 17

Does the dashboard flag patients who need attention?

Accepted Answer

Yes. The dashboard identifies patients who haven’t trained, whose force is declining, or whose quality scores are dropping — so the physiotherapist can prioritise follow-up.

Question 18

How much does it cost?

Accepted Answer

EUR 29 per sensor per month incl. VAT. No hidden fees, no per-practitioner charges, no feature tiers. Everything is included: sensor rental, full dashboard access, clinical messaging, hardware maintenance, and unlimited patient accounts.

Question 19

How does the rental model work?

Accepted Answer

Sensors ship directly to the clinic with a prepaid return label. When a patient finishes their programme, return the sensor. It’s reset, recalibrated, and ready for the next patient. Maintenance and replacement for normal wear are included.

Question 20

What happens if a sensor is lost, broken, or not returned?

Accepted Answer

A fee of EUR 135 incl. VAT is charged per sensor if it is lost, damaged beyond normal wear, or not returned. Normal wear and malfunctions are covered under the subscription.

Question 21

Why per-sensor instead of per-practitioner?

Accepted Answer

Exercise prescription platforms charge per practitioner, per month — more staff means higher costs. Bandcizer charges per sensor, per month. Your cost scales with how many patients you monitor, not how many staff you have.

Question 22

Is there a lock-in period?

Accepted Answer

No. Cancel anytime.

Question 23

Can I start with a small pilot?

Accepted Answer

Yes. Start with a pilot programme to see the impact before committing. We set up everything you need.

Question 24

Are the resistance bands included?

Accepted Answer

No. The sensor works with the flat resistance bands your clinic already uses. Most Nordic clinics stock Theraband Latex Free, which is what the sensor is calibrated for. No proprietary consumables.

Question 25

Who owns the data?

Accepted Answer

You do. The clinic owns patient data collected through the platform. We store and process it — you own it.

Question 26

Can I export patient data?

Accepted Answer

Data export in CSV, JSON (Plotly-compatible), and MAT (MATLAB) formats is on the roadmap and coming soon. The platform is built around data ownership — your clinic’s data will be fully exportable.

Question 27

Is the platform GDPR compliant?

Accepted Answer

Yes. Bandcizer ApS operates under Danish and EU data protection law. A data processing agreement (DPA) is available for clinics that require it.

Question 28

Where is data stored?

Accepted Answer

Within the EU, in compliance with GDPR requirements.

Question 29

How many studies have used the sensor?

Accepted Answer

12 independent peer-reviewed studies published between 2013 and 2024. The studies span measurement validation, knee, shoulder, hip, geriatric, older adult exercise, workplace, and adolescent rehabilitation.

Question 30

Who conducted the research?

Accepted Answer

Independent research groups at Aalborg University, Bispebjerg Hospital Copenhagen, University of Queensland, Copenhagen muscle research groups, Silkeborg Regional Hospital, and Aarhus University Hospital. They chose Bandcizer as their measurement instrument — they weren’t contracted to validate it.

Question 31

Is the sensor the same as the one used in the studies?

Accepted Answer

The hardware and the capacitive measurement method are unchanged from what the research groups used. Six generations of software analysis, same sensor physics. The measurement method is protected by US Patent 9,561,400.

Question 32

The sensor won’t pair with the app

Accepted Answer

Ensure Bluetooth is enabled on the patient’s phone and the sensor is powered on (LED indicator). Move within 2 metres of the phone. If the issue persists, restart both the sensor and the app.

Question 33

Data isn’t showing up in the dashboard

Accepted Answer

Session data syncs when the patient’s phone has internet connectivity. If the patient was offline during the session, data will sync next time the app has a connection. Check that the patient’s app is not force-closed in the background.

Question 34

The sensor halves won’t stay on the band

Accepted Answer

Ensure you’re using a flat resistance band. Tube, loop, and fabric bands are not compatible. The magnets should click firmly on either side of a flat band. If the band is very thin, reposition to where the band is doubled over.

Question 35

How do I reset a sensor for a new patient?

Accepted Answer

Sensors returned to Bandcizer are reset and recalibrated before being reissued. For reassigning a sensor already at your clinic, contact support at info@bandcizer.io.
