RIO Data View app plots real time or stored data of your remote I/O modules and allows control relays or digital outputs channel over the network on your mobile phone. Currently supported remote I/O Modules are Teracom's TCW241 - Ethernet I/O modules and RPIO - Raspberry Pi + Automation Hat remote I/O module. The App can plot data by selecting channels on a screw with a graph view or list view. When relays or digital output channels were selected, the app can control the channels on or off remotely. Feature Realtime Plots Stored data plots Timelined line graph with coloured lines, symbols...etc.f Conversion can be applied to the data before plotting Support software RIO DLUtility: data logger for your remote I/O modules and serve data to this RIO Data View App. RIO Data View Mac: RIO Data View app for macOS

The Amstrad CPC is a semi-professional 8-bit computer with a 4 MHz microprocessor, introduced in 1984. If you owned one back in the 1980's or would have loved to do so, CPCemu is for you. If you would like to use special CPC software today or learn how to program a Z80 microprocessor, CPCemu is for you. You can also use it to watch the demos bringing the CPC to its limits, due to CPCemu's very high graphics and sound emulation accuracy, down to single microseconds. The type of graphics chip ("CRTC") can be selected in the user interface. Of course you can also play one or two of the amazing games still available using the touchscreen joystick emulation. CPCemu was the first emulator that provided emulation of an M4 Board (http://www.spinpoint.org) which provides an SD-card drive C:, configurable ROM slots and even TCP internet connections and HTTP downloads to the CPC. This emulation is compatible to the operating system SymbOS. CPCemu is the first CPC emulator that provides (basic) emulation of an external graphics card with a V9990 graphics processor, in particular for SymbOS. At any time, snapshots of the current state of the emulation can be saved and reloaded later. CPCemu provides real-time emulation and unlimited-speed emulation. Besides, the CPU speed can be switched between normal and 3x or 24x turbo mode. A simple monitor program (debugger) is integrated. It allows CRTC single-stepping (even if a CPU instruction takes more time than one CRTC step).

Verdict
The clearest difference is iOS requirement: CPCemu at 12.0 against RIO Data View's 14.5. On price, ads, in-app purchases and device support there is nothing between them.
