When riding a bike, you don't need a dedicated speedometer. Use your smartphone as the speedometer. It has a neat design and is easy but offers a variety of functions. You can view maps of directions of movement or save routes as GPX, KML files. You can also attach a saved file and immediately email it to them. You can specify a speed range for various situations, such as walking, biking, and driving.

Verdict
The clearest difference is in-app purchases: Quad Calcs at none against Speedometer GPX's 1. Speedometer GPX's advantage is update cadence (every 4 days vs every 2 weeks) and iOS requirement (12.0 vs 15.8.3). On price, ads and device support there is nothing between them.
