PsyPad is an open source platform for facilitating visual psychophysics experiments on an iPad. Using customisable staircases or MOCS, the researcher can control presentation of any stimuli that can be precomputed as PNG image files, including movies. Features include participant accounts, up to 4 response buttons, comprehensive log files, and remote test configuration using the PsyPad server. A demo mode with access to a public gallery of tests also makes PsyPad useful for teaching. The project is open source, with repositories for the application code and example server code. https://github.com/davidlawson/PsyPad https://github.com/davidlawson/PsyPad-Server

Argus Science is pleased to release the latest version of the ETPhone App for use with the Argus Science ETVision wearable eye tracker. This Release builds upon the original ETPhone App by adding real-time gaze computation and recording directly on your iOS Phone or Tablet, allowing increased flexibility and control for eye tracking data collection. With this latest ETPhone Release you may name files, control gain and quality of the ETVision cameras, calibrate participants, record gaze data and control recording to an SD card inserted in the ETVision controller. After data is collected, it is easy to download the gaze data to a PC with Argus Science’s ETAnalysis program which allows the researcher to perform typical gaze analysis functions such as Fixation definition, Pupillometry and blink criteria as well as automated area of interest creation to name a few.

Verdict
The clearest difference is update cadence: PsyPad at every 4 months against ETPhone's every 16 months. PsyPad also leads on iOS requirement (13.5 vs 16). ETPhone's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
