Need advise on getting a wireless timer to shoot time lapse videos with a 5d3

[marcosm]

I've been thinking about getting this one: http://www.amazon.com/Satechi-Bluetooth-Wireless-EOS-D2000-Compatible/dp/B00ANWQMWK/ref=pd_rhf_dp_p_t_4_X1SG which can be controlled by iPhone or iPad and has time lapse capability.
