LINX is the companion app for use with your ElectraStim LINX Electro Stimulator. It not only expands the range of ways you can play with LINX, but also allows for remote control play from anywhere in the world! With this FREE app you have access to an expanded range of patterns and can control the stimulation with your voice, motion or audio files as well as modify the frequency of sensations. You can even create and save your own patterns in a Playlist that’s unique to you and share it with your partner. The LINX app from ElectraStim works on all mobile devices with Bluetooth and Wifi capabilities. There are no ‘login’ or ‘social connect’ options in this app making it entirely discreet and private- the only data we are able to access is for debugging and error reporting purposes. You will require a LINX Electro Stimulator (sold separately) to experience the sensations yourself, but if you wish to connect to other users and take control* then you will just need this app! *please note that connection to another’s person’s unit is only possible if they share their security code.

Verdict
The clearest difference is in-app purchases: ElectraStim Linx at none against Devotion's 10. ElectraStim Linx also leads on iOS requirement (12.0 vs 15.0). Devotion's advantage is update cadence (every 2 days vs every 6 weeks). On price, ads and device support there is nothing between them.
