Goal of the Program

  • First Goal is to provide convenient and full access to all our data from your mobile device.
  • Second Goal is to implement all type of advanced analysis on your data that I couldn’t find in other programs
  • The app was tested with data from forerunner, garminswim, garmin edge, garmin fenix and garmin fit app.
  • It’s intended to handle large numbers of activities (tested with several thousands activities and with activities up to 6h long). For such large archives the initial download can be a bit long, especially if you have an older phone.
  • The app will not let you record any activities, but only display data uploaded from Garmin Connect.

Fist Use

  • when you start the program you will be have to choose and enable download for the service of your choice.
    • Garmin: you can choose the connectstats service, which will pop up a login message or to download from the website in which case you will have to enter your user name and password.
    • Strava: upon first refresh, the strava login page will popup.
  • the app will then start downloading activities when you  refresh by pulling down on the activity list
  • Note that this process can be quite slow if you have a lot of activities. Note that in addition if you use the ConnectStats service for Garmin, the very first time will required a synchronisation that can take some time.
  • You can interrupt the process at any time and it will restart where it left it when you restart the app and start refreshing.
  • While it’s downloading you should be able to look at already downloaded activities but the performance will be slower than after full download completed. If any error occur during that process restart the app and it should restart the download where it left of.
  • If you have issue connecting check the trouble shooting section

How to use it

  • You can refresh by pulling down the activity list
  • You can navigate the different tabs and touching most data will let you drill down on that number.
  • You can touch a graph or the gear button to rotate through the different graphs options or bring in the graph full screen.
  • You can reload an activity to update changes in garmin connect by pulling down on the detail tab
  • You can see full history of any field by selecting the field name in the stats page
  • You can drag to the right the detail view to reveal the sharing page for Google earth or facebook/tweater sharing
  • You can tap the name of an activity to rename it. This will rename it also on Garmin Connect.
  • If an activity was deleted on garmin connect, select it in the app and pull down to refresh. It will then delete it from the app.
  • If you setup the withings service in the settings page, you should see in the details page the closest weight to that date and in the stats an extra scatter plot versus your weight. Currently to refresh you’ll have to go back to the settings page and press refresh. More graphs, auto refresh, etc will be added in later versions.
  • You can setup strava synchronization. In that case any activity you display in the detail pane will automatically be synchronized to strava

  • Straight up excellent ★★★★★
    I don’t write many reviews but ConnectStats deserves one. I use Garmin connect and Strava but to compare volume and count ConneftStats is simpler and superior. It takes Garmin and/or Strava data directly and although the display appears basic, they are highly detailed and comprehensive. It will give you more detail and more insightful information about your exercise than the other app but it isn’t a replacement to them. It’s not replacing strava or Garmin Connect. I love this app and would suffer less understanding about my workouts without it

  • Valuable app ★★★★★
    Provides unique stats and graphics not available elsewhere. For example plots pace vs heart rate or cadence. A tremendous bargain. My favorite ios and data analytics app.
    By JackP2016 for Version 5.0.2
  • Excellent App ★★★★★
    This program lets you sort through your data and view either big picture (many years) or details with ease. The visualizations are in some ways more useful and give you a good view of your progress. A very nice addition to the standard Garmin or Strava visualizations and the author has kept it up to date.

  • Open source! ★★★★★
    Great software, and it's open source so if i don't like something you can fix it yourself theoretically.
    By DarrinC for Version 5.0.2
  • Awesome!!! ★★★★★
    I have used this app for years. I hope Garmin never stops sharing the data, as this app does it all for me. As of today, Aug 9, 2016 it still works with Garmin. Keep up the good work, and. Thank you for regular updates. Live on forever!! 🙂

  • Great running App ★★★★★
    I use this app daily and have been for over 5 years. Great tool to analyze your runs.
    By Kyojin42 for Version 4.6.1
  • Still Better Than Garmin’s App ★★★★★
    This remains my favorite running app ever. I’ve used it for 7 years and 11 marathon training routines. The graphs and aggregated stats are easy to see, scrolling through to find past runs is much easier than other apps. It remains the best out there!
    By Patcalhob for Version 4.6.1
  • Just about all the stats you could hope for ★★★★★
    This really is a great app. Is it a beautiful example of modern app design? No. Does it provide all the stats a fitness nerd could hope to extract from his or her data? Absolutely.
    By Infinite Waterbear for Version 4.5
  • Great app ★★★★★
    Almost think it’s better than Garmin Connect. Certainly works all the time — can’t say that about Garmin Connect.
    By Roger Wedtphart for Version 4.5
  • Excellent app ★★★★★
    ConnectStats is seriously good and a must have for runners. Highly recommended

Chasing Complex Bugs: Power Curves and Best Rolling Curves

The harder category of bugs are when it is related to bad numbers generated from the more complex algorithms in ConnectStats. This is what is now happening with the best rolling plots.

The rolling best curve are one of my favorite feature in ConnectStats, they provide insight I don’t see in many other services. It’s quite common to see a power curve, but I feel the concept extended to heart rate or speed help give people a good sense of the characteristic of a workout. While the concept is simple, it actually can be a bit tricky to implement (at least for me it was). The current version of the app shows quite a few quirks that are obviously wrong, like the below.
