LineScale-3 App is the official iPhone companion app for the LineGrip LineScale-3 Bluetooth Load Cell.
Connect up to four devices simultaneously and monitor live force values, peak loads, battery status, and alarms in real time.
The single-device Dashboard and the Multiplex Dashboard give you a clear overview of all device data at once.
Record sessions as timestamped logs and export them as CSV and PNG files.
Use the Plan feature to place measurement points on a site photo and link them to live devices.
The Calculations screen combines multiple devices with real-time math operations such as sum, difference, and average.
Set independent alarms per device with custom thresholds and sounds - alerts fire in-app, via vibration, and as push notifications in the background.
Use the Apple Watch integration to read values, configure alarms, and control recordings directly from your wrist.
The Repeater feature streams live data via WiFi to other phones for remote monitoring.
With the integrated Simulation-Mode you can fully test all App features without any LineScale connected by simulating data streams for up to 4 connected devices!
Free extra benefit: the app runs fine on iPad, albeit in max. 2:1 (iPhone) aspect ratio with scarlet spacers to fill the screen.
For the full featured & full screen iPad experience refer to our soon to be released dedicated iPad app with many extra features to make full use of the large iPad screens.
All core features are included in the free version, without any bugging ads.
