After a long, long wait, we finally have a working iOS app to control the foc.us tDCS headset. While still needing some polish, the app released in January of 2014 gets the job done, allowing control of current, duration and treatment type.
To get started, you need an iPhone 4s or later or and iPad 3 or later using iOS 7. Given those conditions, go to the App Store, search for foc.us and you should have no trouble locating and installing the app. Then the fun begins!
First – be aware that though this is version 2.0 of the foc.us app, think of it as a 0.99 version. It works, but has much polish and stability to be added yet. You will struggle with it a bit, but once you get the hang of it, you will find it usable in accessing the features of the foc.us headset. As foc.us adds some polish, this should become the app we’ve all been waiting for!
Make sure your foc.us headset is charged and ready to go and that Bluetooth is enabled on your iOS device.
- Start the foc.us app
- Place your headset in “Ready” mode by touching the touch-button for three or four seconds. It should buzz and the blue foc.us logo should blink.
- Touch “Bluetooth” at the bottom of the app screen. The headset should show in the list of available Bluetooth devices as “foc.us gamer”. Touch “Connect”. Note – if you take too long, the headset may drop out of “Ready” mode.
- Touch the “Current” circle and move the slider to the desired current level. If you are new at all of this, I suggest 1.0 mA. Touch “Change” to confirm.
- Touch the “Duration” circle and move the slider as desired. Normally, tDCS sessions are 20 minutes (in research anyway.) Touch “Change” to confirm.
- Touch “Mode”. Unless you have a specific research reason to do otherwise, I’d pick “Continuous” – that is tDCS.
Once the above selections are made, the tDCS session should start immediately.
If your tDCS session does NOT start immediately, the app and your headset have probably lost contact with each other (even though the Bluetooth screen shows otherwise). I suggest closing the foc.us app (double-click home on your iOS device, and flick the foc.us app UP to close it). START OVER at step 1 above.
During the tDCS session, the “Duration” will count down minute by minute. At the end of the session there is a brief “buzz” from the headset to let you know the session is complete.
(Duration counts down as session progresses)
- The app and the headset seem to lose sync with each other if you delay too long in making selections, cancel a session, or do much other than the steps I show above. (Remember it’s really a 0.99 release.)
- The duration reads “00” during the last 59 seconds of a session.
Update to my Free Guide to using the foc.us headset
I’ll be adding these instructions and more to my free guide in the next few days. I’d appreciate any input you have as the objective is to help headset users get the most from the product. The button to download the free guide is on the right side of my main blog page.
