The Challenge
Why Connected Device Apps Are Harder Than They Look
Bluetooth and wireless stability is a constant battle
Maintaining stable connections between a mobile app and a physical device across different phones, OS versions, and environments is technically demanding. Dropped connections and pairing failures frustrate users and erode trust in your product.
Out-of-the-box SDKs limit your product vision
Many manufacturers default to generic IoT platform SDKs to save time. The result is a cookie-cutter app that restricts your UX, limits your branding, and prevents you from differentiating your product in a competitive market.
Security risks grow with every connected endpoint
Each device-to-app connection is a potential vulnerability. Without proper encryption, authentication, and firmware validation, your IoT product becomes a target and a liability
Deep Expertise in Device-to-App Communication
Why IoT Manufacturers Partner with Sidekick Interactive
We’ve spent years solving the hardest problems in mobile-to-hardware connectivity. Our engineers understand the nuances of Bluetooth Low Energy, Wi-Fi provisioning, and real-time data streaming at a level that generic app shops simply don’t.
“A connected product without a great app is just hardware with unrealized potential. We make sure your users see the full value of what you’ve built.”

Who We Work With
IoT Clients We’ve Worked With
Client
ABB Emergency Lighting
About the company
ABB is a global leader in electrification and automation technologies. Their emergency lighting division produces safety-critical products used in commercial and industrial buildings worldwide.
Sidekick's role
Sidekick Interactive developed the companion app for ABB’s emergency lighting product line, solving the connectivity challenge of managing dozens of BLE devices from a single mobile interface. The app handles multi-device Bluetooth pairing, real-time status polling across heterogeneous hardware, and background firmware updates, all while maintaining stable connections in RF-noisy commercial environments.
Client
Danlaw CleverCharge
About the company
Danlaw is an automotive technology company specializing in connected vehicle and EV charging solutions. CleverCharge is their consumer-facing EV charger product line designed for residential use.
Sidekick's role
Sidekick Interactive engineered the CleverCharge companion app with a focus on reliable hardware communication. The core challenge was achieving consistent BLE pairing and Wi-Fi provisioning across hundreds of Android and iOS device variants, each with different Bluetooth stack implementations. The app abstracts this complexity behind a simple setup flow that guides homeowners through device connection in under two minutes.
Client
FLO EV Chargers
About the company
FLO is a North American EV charging network operating thousands of stations, each requiring reliable mobile-to-charger communication for session initiation and management.
Sidekick's role
From an IoT perspective, the FLO project challenged Sidekick Interactive to build an app layer that communicates reliably with a heterogeneous fleet of charger hardware across varying network conditions. The connectivity architecture had to handle real-time status polling, session state management, and graceful fallback when cellular coverage fluctuates, all while maintaining responsiveness for impatient drivers at the charger.
Our Process
Our Approach to IoT App Development
Connected device projects demand a development process that accounts for hardware timelines, firmware dependencies, and the unpredictability of real-world wireless environments.
Hardware Review
We study your device specifications, communication protocols, and firmware capabilities to understand what the app needs to support.
Connectivity Architecture
We design the Bluetooth, Wi-Fi, or cloud communication layer, including pairing flows, data formats, and fallback mechanisms.
UX for Physical Products
We create interfaces that reflect your device’s real-world behavior, with responsive controls and clear feedback for every hardware interaction.
Parallel Development
We build the app in sync with your firmware team, sharing test protocols and aligning release milestones.
Device-App Testing
We test across a matrix of devices, OS versions, and environmental conditions to ensure reliable connectivity in real-world use.
Production Launch & Monitoring
We deploy to app stores and implement monitoring for connectivity issues, crash reports, and user behavior analytics.
The Technology Behind Reliable IoT Apps
For IoT projects, native development (Swift and Kotlin) is often preferred for its superior Bluetooth performance and hardware access. We advise on the right approach based on your connectivity requirements.
React Native
Flutter
Swift
Kotlin
FAQ – Mobile App Development for Connected Devices
Do you have experience with Bluetooth Low Energy (BLE)?
BLE integration is one of our deepest areas of expertise. We’ve built apps that communicate with medical devices, EV chargers, emergency lighting systems, and consumer electronics, each with different BLE profiles, data throughput requirements, and pairing protocols.
Should our IoT app be native or cross-platform?
It depends on your connectivity needs. For apps with heavy Bluetooth interaction or real-time hardware control, we typically recommend native development (Swift for iOS, Kotlin for Android) for maximum stability. Cross-platform can work well for cloud-connected devices with simpler communication patterns.
How do you handle the fragmentation problem across Android devices?
We maintain a comprehensive device testing matrix and account for manufacturer-specific Bluetooth implementations. Our engineering team has documented workarounds for known issues across Samsung, Pixel, Xiaomi, and other major Android OEMs.
Can you build apps that manage multiple devices?
Yes. We’ve built fleet management interfaces for enterprise IoT deployments, including device grouping, role-based access, bulk operations, and centralized dashboards.
What does a typical IoT app project timeline look like?
Most connected device apps take 4 to 7 months, depending on the complexity of the hardware integration. Projects that require coordination with firmware development cycles or certification processes may extend to 8–10 months.
What investment is required for an IoT companion app?
The main cost drivers are connectivity complexity, number of device variants supported, and whether you need consumer-facing simplicity or enterprise fleet management. Single-product companion apps generally fall in the $50,000 to $90,000 range. Multi-device enterprise platforms with OTA updates, analytics, and admin tooling can reach $100,000 to $250,000+ depending on scale.
Do you coordinate with our hardware and firmware teams?
Always. Tight collaboration between app and firmware teams is essential for IoT projects. We establish shared testing environments, aligned sprint cycles, and integrated QA protocols from day one.
