HRLogger

If you have a heart rate monitor and you want to log your heart rate in a way to choose yourself how to handle the data, HRLogger is the right tool for you.
It saves your heart rate logs in the commonly used .csv format on your phone or directly uploads it to your private FTP server.
Features:
Set a marker at any time while logging your heart rate, to mark events like when you started with the workout or when you face a scary situation in life, like before you enter your job interview/salary negotiation or a bungee jump ;)
Zoom able Graph of this days measurements
Shows minimum, maximum and average HR of this day
Automatic and manual upload to your own FTP server
Decide name and location of the log file on your phone
Be in 100% control of your data
Easy post processing of your data - just open it in excel and plot graphs, or use it in your self written software
Storing the data in an human readably format
Works with ANT+
Gives you haptic feedback when the first HR is received, so you don't have to look at your phone.
Shows your HR on your wish also on your lockscreen - so you don't have to open the app all the time to keep track
Just pull down the status bar in any App to see your current HR
Supported Sensors:
Currently I only had Wahoo TICKR models for testing. If anybody can provide me with more sensors, I can implement them in future builds and you will be named here in a honor section ;)
Codes:
For simple post processing there are codes saved in the logs to identify important moments.
The data is saved in the format:
time code HR Info1 Info2
101 New Service started
102 Connection time
103 Service terminated
105 Average Heart Rate
106 detailed time
108 marker
109
new file
401 Service was destroyed before connection was established
402 Connection to Sensor was lost!
403
Service was running over 10 hours continuously(This is implemented if you forget that you are connected and prevents the battery from draining. The active connection will be disconnected after 10 hours)
404 Device was lost
Error handling:
Check if the sensor is connected correctly and if the lights on it are blinking. Otherwise take it off and on again.
Disconnect in the App and try connecting again.
If it does not help, change the sensors battery and try again.
If you cant push the Graph button, rotate the phone or close and reopen the app. After the first connection of the date it stores some hr data before being able to display a graph
None of your data is sent to us or anybody else!
(beside of the FTP server you can specify yourself)
You have 100% control over your own data
