Not quite sure if this is a ~tech question, or a ~sport question, or a ~health question. But at least it's a question!

I have a Garmin watch, and so does my wife. They track our activities. We would like to compete in challenges, but Garmin's challenge options are quite limited. Through Garmin, you can compete for the number of steps, or distances ran or swam and such, but those don't really work very well for us.

I was wondering, are there any apps that work on both iOS and Android, sync with Garmin Connect (either directly or through Apple Health / Google Health Connect), have a sensible privacy policy, and offer some or all of the following types of challenges, which I think would be more interesting:

• Total time exercised (either any exercise type, or specific sports)
• Time spent in "vigorous" exercise
• Time spent in "zone 2" exercise (or another zone)
• Active calories burned (either total, or percentage of your resting calories)
• Number of exercise sessions
• Number of consecutive exercise days, i.e who can maintain the longest streak (allowing rest days)

Does anything like that exist?

I also have a bonus question:

Garmin has Expeditions, which track the distance you have walked or run, and once you reach your Expedition goal (say, "walk the distance of the Appalachian Trail"), it tells you that you have reached your goal and gives you a badge. I like the basic idea, but the implementation is quite bland.

Are there any Expedition type apps where the app not only tracks the number of steps against the total needed, but actually shows on a map where you'd be currently going if you actually were walking the Appalachian Trail or something, and gives you notifications when you reach some interesting points along the way, with pictures and a little bit of information about the place? Now, that would be something!

The plan only costs $1 a month. Apple can almost certainly eat that cost, and anyone who cannot complete their monthly exercise challenge because of illness or injury can probably still afford the $1 to keep the plan going.

The monthly challenge in the Fitness app is tailored to each user based on their exercise habits, right?

It's Friday and I'm on a quest to discover new music. The algorithms have been letting me down lately. So let's just build a communal playlist!

Playlists links:

• Spotify
• Youtube (Thanks, @SloMoMonday)
• Apple Music (Thanks, @Weldawadyathink)

I'll start by adding my 5 song choices.

Leave a comment with the names of the songs you would like to have added to the playlist (let's limit it to no more than 5 per user) and I'll add them. There are no other rules -- you could choose your favorite songs of all time, what you're listening to at the moment, or anything in between.

(I guess the only other requirement is that it needs to be available on Spotify, unless somebody wants to mirror the playlist on other services)

PS. Deimos, mods, et al, I hope this isn't too gimmicky. I think Tildes is as tight-knit of a community as you can find on the internet these days and I see this as just another small way to further that communal experience.
