A Modbus app for iPad
FieldKit runs on iPad with the same client, server, profiles and logs as on iPhone, and more of it fits on one screen.
Two columns on one screen
The client and the register browser sit side by side, so you read a value and see the result without changing screens. Live monitoring and the write form stay in view during commissioning.
Good for a bench or a control cabinet
A larger screen helps when you compare a register list with a vendor's PDF in Split View, or leave a chart running next to a machine. Remember that monitoring and the server run in the foreground, so keep the app on screen.
The same app, one purchase
The App Store listing covers iPhone and iPad, so you buy it once. Profiles stay on each device. Move them between devices with export and import: the default export removes hosts, labels and values, and Include private details keeps them after you confirm.
Before you buy
Is there a Mac version?
Not at the moment. FieldKit runs on iPhone and iPad with iOS 18 or later.
Does the iPad need cellular or Wi-Fi?
Find devices needs Wi-Fi. A manual connection needs a network route to the device.
