Neurotechnology & Wearables
We build BLE-connected mobile apps that stream EEG, fEMG, EDA, and HR/HRV data in real time. Zero packet loss. Research-grade reliability. Trusted by neurotech companies across Canada.
Building a mobile app for a brain-sensing device isn't like building a social app. The stakes are different.
Most mobile dev shops have never touched BLE streaming, let alone multi-channel biosignal data. You end up with:
We've already solved these problems. Our engineers understand neurotechnology from the firmware up:
We work with neurotechnology and biomedical companies building the next generation of brain-computer interfaces and biometric wearables.
Our team has hands-on experience integrating and streaming these biosignals over BLE in production mobile apps.
Electroencephalography: brain electrical activity
Facial electromyography: muscle activity
Electrodermal activity: skin conductance
Heart rate & heart rate variability
Photoplethysmography: blood volume
Geolocation: spatial context for field studies
Real neurotechnology projects we've delivered, from multi-sensor EEG headsets to biometric research platforms.
A mobile app capturing brain activity (EEG) from the frontal lobe and temporal regions, facial expressions (fEMG), electrodermal activity (EDA), heart rate variability (HR/HRV), GPS, and POV camera, all streamed simultaneously over BLE in real time.
The app manages 6 concurrent BLE data channels with zero packet loss, performs on-device buffering for intermittent connectivity, and exports research-grade data files compatible with standard neuroscience analysis tools.
Fred Simard, RE-AK Technologies
A mobile application for CLEIO's brain-sensing headset, enabling real-time EEG data capture and visualization. Built for researchers and clinicians who need reliable, continuous neural data streaming from wearable devices.
The app handles automatic device discovery and pairing, live signal quality indicators, session recording with timestamped markers, and cloud sync for multi-site research collaboration.
Designed with an intuitive interface that allows non-technical clinicians to operate complex neurotechnology hardware without training.
"Zawar joined CLEIO's Android development team on an engagement through DEVSFLOW Technologies and quickly proved himself to be a dependable, communicative, and professional consultant. He integrated smoothly into the project team, ramped up on the project context efficiently, and consistently delivered against the cadence set by the client."
What clients say
Thank you for the reliable application you delivered, not a single failure since I've been using it.
Built around how hardware companies actually ship. We sync to your firmware cadence, not the other way around.
Day 1
We read the GATT services, BLE characteristics, packet structures, and known firmware quirks. We ask the questions that surface integration risk early, before any code is written.
Weeks 1 to 2
We design the communication protocol with your embedded team. Packet sequencing, reconnection logic, error recovery, throughput targets. Documented contract before app development starts.
Weeks 3 to N
Working builds connected to your dev boards every 2 weeks. We adapt as your firmware iterates. Same Slack, same Linear, same review cycle as your internal team.
Pre-launch
Real devices, real network conditions, real users where possible. We instrument session recording so we can debug edge cases that only show up in the field.
Launch and beyond
We handle App Store and Play Console submission. After launch, monitoring stays on so OS updates, dependency drift, and device fragmentation do not surprise you.
Deep expertise in the specific challenges of neurotechnology and biometric mobile development.
Custom GATT service integration, MTU negotiation, connection parameter optimization, and multi-peripheral management for complex sensor arrays.
High-throughput data pipelines handling 250Hz+ sample rates across multiple channels simultaneously without dropped samples.
Signal filtering, artifact rejection, feature extraction, and quality metrics computed locally for immediate feedback without cloud latency.
Full recording capability without connectivity. Local storage with background sync when network is available. No data loss, ever.
Export in EDF+, CSV, and custom binary formats. Timestamped event markers, session metadata, and compatibility with MATLAB and Python.
Extensive testing across Android fragmentation (50+ devices) and iOS versions. BLE stack workarounds for known chipset-specific bugs.
Yes. We often start when firmware is still being iterated on. We'll work directly with your embedded team, test against dev boards, and adapt as your hardware stabilizes. Early engagement actually reduces risk.
Native iOS (Swift) and Android (Kotlin). For BLE-heavy applications, we strongly recommend native over cross-platform because the BLE stacks differ significantly between platforms and native gives us full control over connection behavior.
We maintain a tested device matrix and have workarounds for known chipset-specific issues (Qualcomm, MediaTek, Samsung Exynos). We test on physical devices and have automated BLE integration tests.
That's how we prefer to work. We'll join your communication channels, participate in hardware/firmware reviews, and coordinate protocol changes directly with your embedded engineers.
Our apps implement packet sequence verification, local buffering for BLE disconnections, and automatic session recovery. In production across both RE-AK and CLEIO deployments, there have been zero reported incidents of missing data in recorded sessions.
It depends on sensor complexity and feature scope, but a typical single-device BLE companion app takes 3-5 months from kickoff to App Store submission. Multi-sensor platforms like Nucleus-Kit are longer.
