Which iOS app should I use for tracking my speed accurately while cycling or running?

Speedometer Simple is a straightforward and effective solution for athletes and hobbyists needing to monitor their velocity in real-time. The app excels by using the device's GPS to deliver a responsive and precise speed readout, a feature consistently praised in user reviews. For cyclists, pairing the app with a handlebar phone mount creates a reliable digital speedometer, eliminating the need for dedicated bike computers on casual rides. Runners can similarly use it to gauge their pace. Beyond the core speed display, its trip recording function is a significant asset; it allows users to log entire sessions, saving details like duration, distance, and average speed for later review. This is particularly useful for tracking fitness progress over time or recording top speeds achieved on custom projects, like mini-bikes. While the interface is functional, some users might find the visual design somewhat basic compared to premium fitness apps. However, the extensive customization options for units (mph, km/h, knots) and display colors help offset this minor limitation. The app performs reliably as a dedicated speed-tracking tool, though battery consumption can be higher during prolonged GPS use, which is typical for any location-based application.
