What is an IoT mobile app?
An IoT mobile app is a phone app that connects to a physical device, such as a pump, sensor or machine, to set it up, show its readings and control it. It talks to the device over Bluetooth or Wi-Fi nearby, and through the cloud when you're away. MGT builds IoT apps for iOS and Android with React Native and Swift.
The problem
The app is how people judge your device.
Setup is confusing
If pairing fails in the first five minutes, the device gets returned or ignored.
Readings stay on the device
People have to walk to the machine to know what's going on.
Nobody hears the alarm
A problem at night or on a weekend goes unnoticed until it's expensive.
Remote control feels risky
Without confirmation, nobody knows if the pump really turned on.
What we build
What your app can do
Live readings
Values, status and trends shown in plain words and clear units.
Push alerts
Instant notifications when a reading crosses a limit or a device goes offline.
Remote control with confirmation
Start, stop and adjust equipment, and see when the device confirms it.
Local control over Bluetooth
Keep control on site even with no internet.
Schedules and automation
Run equipment on a timer or automatically based on readings.
Users and roles
Owners, operators and technicians each see what they need.
History and reports
Look back at readings and events, and share reports.
Options
Local control, remote access, or both
Near the device
Local
Bluetooth or local Wi-Fi. Fast and works without internet. Ideal for setup and on-site control.
Anywhere
Remote
Through a gateway or cloud over Wi-Fi or 4G. Check readings and control equipment from home.
Recommended
Both
Local when you're close, remote when you're away. The app switches automatically.
Use cases
What people use it for
- Start and stop pumps, motors or diesel engines
- Watch water quality, tank levels or temperature
- Get alarms on your phone at any hour
- Set up a new device in minutes

Frequently asked questions
Do you build for iOS and Android?
Yes. We build apps for both, and publish them to the App Store and Google Play under your account.
Can the app work without internet?
Yes. With Bluetooth or local Wi-Fi, people can read and control the device on site. Changes sync when the connection returns.
Will it work with our device?
If your device has Bluetooth, Wi-Fi, a gateway or a cloud connection, almost certainly. We test with the actual hardware your customers receive.
Can the app carry our brand?
Yes. Your name, logo and colours, published under your developer account.
Is remote control safe?
Commands are confirmed by the device before the app shows them as done, and you choose which actions need extra confirmation or a PIN.
How long does an IoT app take?
A first working version with pairing, readings and alerts usually takes a few weeks. More features add time, and we agree the scope upfront.
Let's work through your device's first five minutes.
