@revenuecat.com is there an option, or can we get an option, to toggle the graph to not start with 0 but with the lowest value in the chart? This graph looses a lot of nuance imo.

Testing different weather providers. The ones that let you easily test the data, actually have poor data quality 🥲
The other ones force me to do sales calls, which I try to prevent.

Showing a notification for Android users on the iPhone build of your app is not the cross platform code share we’ve hoped for 😅

Still liking the design of my very first published React Native app from ~7 years ago.

Whenever my app detects two heli’s responding to the same incident, a “major incident” notification goes out to the users.
This spikes traffic to the app so much the load time goes from <1s to ~10s. Need to look into better handling this spike 😅

Live data is the most important thing I’ve got for my apps. I’ve built in multiple fallbacks, alerts and automated script restarts when the data stream starts to fail.
However these notifications never fail to raise my heartbeat 😅

Ok let’s get this party started! I’ll be posting mostly here about my two apps AirAssist.app and Waterbomber.app! And perhaps some developer related thoughts in between!
Always looking to get the conversation started on anything product and design related 🙌
