Mobile Apps
iOS & Android Apps for Connected Devices
We specialize in commercial and medical device apps where connectivity, security, compliance, and usability are critical.

What Sets Us Apart
MObile Apps in Connected Systems
Apps are where your connected system gets judged.
Mobile apps are the primary touchpoint for your users and where your entire connected product is evaluated. Users don’t see firmware constraints or cloud latency; they see an experience that either works or fails.
We build apps with system-level awareness. Because we work across firmware, mobile, cloud, and UX, we design the mobile experience around what the system can reliably deliver.
The Result: Mobile apps that integrate cleanly with your connected device ecosystem, handle real-world connectivity, meet regulatory constraints, and scale from beta to production.

What we solve for
Mobile Development at Every Stage
Whether you’re building from scratch, validating user workflows, looking to accelerate development, or fixing critical production issues, we can help.

HOW WE WORK
Integration & Regulatory Evidence From the Start
We coordinate across disciplines, validate with real devices, and build regulatory evidence as we develop to prevent failures at integration and FDA review.

Cross-Discipline Integration
Mobile coordinated with firmware, backend, and clinical teams.
We work alongside your firmware, backend, and clinical teams throughout development, not just at integration points. Mobile architecture decisions account for device constraints, API capabilities, and clinical workflows from the start.
Example in practice: Hardware-in-the-Loop testing validates connectivity with real BLE devices, catching edge cases that simulators can’t replicate.
Offline-First Architecture
Data integrity is maintained even when connectivity fails.
Mobile apps for medical devices must be able to handle intermittent connectivity. We architect apps with local data persistence, sync conflict resolution, and queue management from the start—ensuring data integrity even when devices disconnect or users go offline.
Example in practice: When a glucose monitor loses a BLE connection mid-reading, queued data syncs automatically upon connectivity resume, with conflict resolution handling overlapping measurements.


Regulatory Evidence as we build
IEC 62304 traceability and verification are integrated into the development process.
We don’t save compliance for the end. Requirements traceability, risk mitigations, and verification evidence are built alongside code. Formative usability testing happens in parallel with development.
Example in practice: Each sprint delivers not just working features but also the traceability matrices, risk analyses, and test protocols needed for your FDA submission, and prevents last-minute documentation scrambles.

Apps That Carry the Weight of the Whole System
From consumer wellness to Class III medical devices, mobile apps shipped for real products, users, and regulatory submissions.

Reliable Device Connectivity for a Care-at-Home Platform
Current Health builds the platform hospitals use to care for patients at home instead of in a bed.
A patient goes home with a wearable and a kit of connected devices, and their vital signs and readings flow to a clinician’s dashboard, with telehealth on top.
For a patient, that means recovering in their own bed with someone still watching. It also means hospital-grade monitoring riding on consumer Bluetooth, in homes no one controls, across medical and consumer devices from different makers that each behave differently.


A Fashion Smartwatch Shipped by the Millions
A global fashion brand’s smartwatches reached millions of wrists across several product generations, and they were designed to look like watches first.
Under the face they tracked health and activity, moved logs and firmware updates to a phone over Bluetooth, and ran on a battery sized for a fashion case.
For the wearer, that meant a watch chosen for how it looked that still did what a smartwatch does. It also meant pairing with every phone and OS version its wearers owned, each handling Bluetooth its own way, at a scale where a one-in-a-million quirk came up every day.


A Meditation Device Built to Survive Its First Five Minutes
Hyperice’s Core™ Meditation Trainer is a handheld device you cup in both palms, with heart sensors in the handles and a pulse you breathe along with.
It reads heart rate and heart rate variability to tell when you have settled into a focused state, and the app’s guided sessions respond to that.
For someone who wonders whether they are meditating right, that means a device that can tell them. It also means a consumer product whose first act out of the box is updating its own firmware over Bluetooth, in a living room, where a failed update is a returned product.


Sleep Apnea Therapy, Connected From Body to Cloud
Inspire® is the first FDA-approved neurostimulation therapy for moderate to severe obstructive sleep apnea.
A small implant stimulates the nerve that controls the tongue in time with the patient’s breathing, and a connected system sits around it, with a Bluetooth remote the patient holds, an app, and a clinician web portal that monitors the implant wirelessly.
For someone who could never live with a mask, that means sleeping with nothing on their face and starting therapy with a click. It also means the system around a Class III implant has moved through several device generations while every implant already placed stays in a body for years, so no part of the system can change without accounting for every implant in the field.


Next-Generation Remote Management for a Cath Lab Device System
One in four angiography patients has chronic kidney disease, and the contrast dye that makes the procedure possible is hard on the kidneys.
Osprey Medical’s FDA-cleared DyeVert™ PLUS diverts part of the dye before it reaches the patient, cutting the amount delivered by about 40 percent with no loss of image quality, and tracks each patient’s cumulative dose against their kidney function in real time.
For those patients, that means a heart procedure with less risk of kidney injury. It also means a tablet talking wirelessly to bedside devices inside a cath lab, one of the noisiest radio environments in a hospital, where nothing can drop mid-procedure.


A Tinnitus Therapy SaMD, Concept to FDA Clearance in Months
One in ten people lives with persistent tinnitus, the ringing that does not stop.
PNQ Health’s therapy is software. An iOS app delivers personalized sound therapy through ordinary earbuds, and the app itself is what the FDA cleared, as Class II software as a medical device.
For a patient, that means treatment at home, self-guided, with a clinician overseeing it remotely. It also means the app is the entire clinical product, so it has to hold to a medical standard while feeling like something a person opens every day.


A Connected Care Platform Around an Implanted Insulin Pump
Portal Diabetes holds FDA Breakthrough Device designation for the Portal Pump™, an implantable insulin delivery system.
The pump is designed to sit in the abdomen, dose from a continuous glucose monitor with a heat-stable concentrated insulin, and take refills in a clinic after weeks or months.
For someone with type 1 diabetes, that means no carbohydrate counting, no meal announcements, and no waking in the night. It also means a loop that closes with no one in it, which has to be trusted before it is ever implanted and then stays in for five to seven years.


A Non-Invasive Cardiac Assessment Platform for Clinical Studies
Knowing how well a failing heart is pumping usually takes an echocardiogram and a trained operator, or a catheter threaded into the heart.
Sensydia’s Cardiac Performance System reads ejection fraction, cardiac output, and pulmonary artery pressure from disposable sensors on the chest, in minutes, at the bedside. Its ejection fraction measurement was first FDA-cleared in 2018, and the full platform holds Breakthrough Device Designation.
For a patient in an ICU or emergency department, that means answers without a referral or a procedure. It also means one measurement running across sensors, a gateway, a tablet, and the cloud, carrying patient data the whole way, while the platform is still being proven in clinical studies.


An Implanted Therapy Its Clinicians Configure From Anywhere
A stealth-stage medical startup is developing an implanted neuromodulation therapy that its clinicians can adjust without the patient in the room.
For the patient, that means a therapy that changes when it needs to instead of at the next appointment.
It also means every adjustment travels from a clinician’s screen to a device inside someone’s body, and that path has to be trusted at Class III stakes before anything is implanted.
