Ride Journal supports bluetooth sensors for recording heart rate, bike speed, bike cadence, power and other data.
We have tested Ride Journal to work with:
Customers have reported the following devices to work well with Ride Journal:
Additionally Ride Journal should support any bluetooth smart compatible heart rate sensor, bike speed sensor, bike cadence sensor and power meter, such as:
If you've tested any of these devices with Ride Journal or know of any other device that works successfully, then please let us know.
When the app starts up and connects to your Barometer, it retrieves your current GPS position and then calls the Bing Elevation API to retrieve the current altitude for your position, if the Bing API is unavailable, it uses the current GPS altitude.
This altitude is then used as a baseline for the current barometric pressure reading, subsequent changes in pressure then calculate the delta from this baseline.
The baseline is updated every 15 minutes.
The speed graph is generated from the smoothed speed data points, whereas the max speed is based on the raw speed data.
All online services such as Strava employ their own smoothing models to the data uploaded. This is an attempt to remove anomalous readings (i.e. a sudden spike in speed for instance). Since each service employs their own models, you will always get slightly different results.
Ride Journal has its own algorithms to generate your stats based on the raw data available, however when we upload to online services, we also send the raw data giving each service a chance to handle the data in its own way.
Overall it doesn't matter whether each service is slightly different, what does matter is that they're consistent allowing you to see how you're improving.
If your sensor disconnects for whatever reason, Ride Journal will attempt to re-establish connection, if it cannot do this within a certain time frame then it will notify you with an alert so that you can rectify the problem.
This is dependent on a number of factors such as which phone you have, whether the radio's are on (cell, wifi, bluetooth), whether the screen is on, how many sensors you have connected and so on.
Here are some examples of the sort of times you can expect in certain circumstances using a Lumia 920:
A good way to increase battery life is to use a portable USB charger, these are normally quite small (similar to a lipstick tube) and can be easily mounted on the top tube to connect to the phone if it's mounted on the handlebars.
Here are some example portable USB chargers:
It's something we may think about in the future, but no definite plans to at the moment.
Currently we export GPS based workouts in the .GPX format and Turbo trainer workouts in the .FIT format.
In a future update we plan to support more formats and allow you to choose the format to use at the time of export.
We plan to add support for additional formats in future, for now GPX is widely supported by many online services.
