oilCHECK
Read full descriptionHide full description
Enter the flight time of your last flight, enter the oil level status of your airplane engine and the amount you refilled - and get the average oil consumption of your engine. You can also set Oil Changes and the app will tell you how long you have flown since the last oil change. Turn your device by 90 degrees and see a graph that shows the average oil consumption per flight. After every Oil Change a new page is created and you can scroll through them horizontally.
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.

The clearest difference is update cadence: WXStar at every 6 weeks against oilCHECK's every 39 months. oilCHECK's advantage is iOS requirement (12.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
