WXStar

The WXStar app allows you to fill in gaps in GDL90 navigation data sent to ForeFlight, Garmin Pilot or SkyDemon when using the WXStar device. This way you do not get any disturbing warnings in your navigation app when the WXstar device is not connected via WiFi, especially while the Starlink Mini reboots.

Verdict
The clearest difference is price: WXStar at Free against Altimeter+'s $1.99. Altimeter+'s advantage is chart position (#21 vs unranked) and iOS requirement (11.1 vs 15.6). On update cadence, ads, in-app purchases and device support there is nothing between them.
