IoT App Development

Mobile and web apps that pair with connected hardware — BLE/Wi-Fi device control, real-time telemetry dashboards and the cloud backend behind them. We can also design and build the hardware itself: PCB design, prototyping, and bulk production for a complete IoT product, not just the app.

Overview

What this service covers

Mobile and web apps that pair with connected hardware — BLE/Wi-Fi device control, real-time telemetry dashboards and the cloud backend behind them. For projects that need it, this extends to the hardware side too: schematic design, PCB layout, prototyping and bulk manufacturing support, so a complete IoT product — device and app — can be handled by one team instead of coordinating separate app and hardware vendors.

⚡ Hardware Add-On

Also need the hardware built? PCB design, prototyping & bulk production

Most IoT projects need more than an app — they need a board. Schematic capture, PCB layout, prototyping and manufacturing support run alongside the app as one engagement, so the app's BLE/API contract and the board's pinout are designed together instead of guessed at from a datasheet after the fact.

What we do on the hardware side

  • Schematic capture and multilayer PCB layout
  • Power-supply and power-electronics design
  • Component selection and footprint verification
  • RF-aware layout for boards carrying a Wi-Fi, BLE or LoRa module
  • Design-for-manufacturing (DFM) review before release
  • Gerber, BOM and pick-and-place file preparation
  • Bulk / production manufacturing coordination once a design is ready to scale

Design

Schematic and PCB layout, sized and powered to match what the app and firmware need.

Prototype

A first working board to validate the design before committing to a production run.

Produce

DFM review, then BOM, Gerbers and manufacturer coordination once the design is ready to scale.

Client Problems

Problems this service solves

  • Working hardware exists but there's no way for a user to control or monitor it from a phone or browser.
  • A single cross-platform app is needed instead of separate native builds for each device platform.
  • Real-time data is needed instead of relying on a device's small onboard display.
  • An existing app's BLE or Wi-Fi connection to the device is unreliable in the field.
  • A product concept exists but there's no schematic or board yet, or an existing board has noise, thermal or reliability issues.
  • A design needs to move from a one-off prototype toward a small or bulk production run.

Development Process

How we approach a project

  1. 01Requirements & device contract

    Map the screens and the data the app needs to exchange with the device — including PCB design if the hardware doesn't exist yet.

  2. 02BLE/API integration design

    Define the contract between the app, the hardware and the backend.

  3. 03App & hardware development

    Build the Flutter app and any web dashboard, alongside PCB layout and prototyping if that's part of the project.

  4. 04Device pairing, field testing & production

    Test against real hardware, then move to bulk production once the design is validated.

Deliverables

What you receive
