Leon Snyman’s Magic MonitorX is a handy little app for displaying data on an iOS device over Bluetooth –
Magic Monitor is a unique customizable application for displaying different values from MCU’s like ARDUINO, Propeller, Basic Stamp, PIC’s or other peripherals that communicate via UART. The application uses the HID profile over bluetooth connection which is simply text strings of the values you want to display.
You can choose up to 6 display boxes and each box can have a different unit. Also available are 6 LED’s that may be turned ON and OFF as required by simple text command from your MCU device. A Text box is also available to send instructions or messages to the user.
