Treeline v0.17.1 is out. Gear is a real thing now: add your bikes and shoes, apply them to past activities (with undo), and watch the mileage and replace-me warnings add up. Installs as an app on your phone too, and the Back button finally works.

Weve had an influx of users in the last 12 hours!
@pyxorium.com officially became the first non @larakin.systems account to share an acitivity.
That activity share increased traffic to our appview exponentially.
That uncovered lots of backed and fronted issues.

Treeline v0.12 AND v0.13 just landed back-to-back! 🌲🚀
Having 1 active user (me) has been great for shipping fast, but it’s getting to be time for others to start using it too.
Can’t guarantee no breaking changes yet, but I promise to treat your data as carefully as my own.

Another minor app update today.
We did some better trail and segment matching, cleaner oauth flows, and better deep linking to socials.
I know. boring still. but once we get the core systems running well we will start building fun features!
Gear tracking, cool visualizations and maps, and more!
