BLExAR

Great app for using BLE with an Arduino. Good function set allowing direct control of I/O channels, messaging back and forth through a console, and the ability to download data from the arduino, plot it, and email it as a text file. Great customer support!

After trying out several different BLE apps I was finally able to view and log serial data from my arduino. Easily saves the data to a csv file and sends to an email address. Perfect and easy. Great technical support as well! Highly recommend.

I have downloaded 5+ other apps but they all are geared toward controlling Arduino with iPhone not sending sensor data TO iPhone . Had a few initial issues (self inflicted) but support staff responded within minutes to my questions and I was graphing sensor data immediately thereafter.
