★★★★★Royal Match is not a good game11/24/2024
I’m dumb but I’m sure it’s useful🤷🏼♂️
I don’t understand it but it seems really cool and useful for researchers and Chat gpt actually recommended it to me. This is now gonna be my compass app.

Zero effort to contribute to cool research
Just open the app and set how often you want to send them data. These types of apps are a great way to harness the power of your iPhone and with no effort make a positive contribution. Nice touch adding achievements for contributions and locations. The magnetic information is interesting to see but that’s about it. Just know your contribution will help other researchers.

Excellent Info
I travel the world for a living. Knowing the correct Mag Variation has come in handy. The latest version includes an excellent compass which gives both True and Magnetic North. It is nice to be able to contribute information for this program. I find that it doesn't effect my battery usage that much.
