What is PaceShouter? PaceShouter is a simple, hands-free running pace tracker that uses your device’s GPS and text-to-speech features to provide real-time audio feedback on your pace. Designed for runners who prioritise convenience, safety, and focus, PaceShouter keeps you informed without distracting you from your run. Modes Available: PaceShouter offers a variety of modes to track your pace during your runs. You can choose as many modes as you like to receive multiple types of audio feedback simultaneously: - Current Pace: Stay updated on your current pace in real-time, so you can adjust as needed. - Average Pace: Get an overview of your average pace throughout your run. - Split Pace: Track your pace for each individual segment or lap, helping you identify your performance at different stages. - Target Pace: Set a pace goal, and receive audio alerts when you’re above or below your target pace, helping you stay on track. - Tempo: Get feedback on your cadence or tempo, perfect for improving your stride and maintaining efficiency during your runs. Whether you’re focusing on staying consistent, achieving specific targets, or improving your tempo, PaceShouter lets you mix and match these modes to suit your needs. Track multiple aspects of your pace at once, and get the feedback you need to optimise your performance. Audio cues offer several key benefits over visual ones: - Stay focused: No need to look at your phone or watch, keeping your focus and rhythm uninterrupted. - Increased safety: With audio feedback, you can keep your eyes on the road, preventing accidents or trips. - Accessibility: If your phone’s tucked away in an arm strap or pocket, you still get real-time updates without needing to stop or fiddle with your device.

Verdict

The call

The clearest difference is review sentiment: PaceShouter at 100% against Polar Flow's 50%. PaceShouter also leads on update cadence (every 4 days vs monthly). Polar Flow's advantage is rating (4.6 vs 1.0) and ratings volume (50K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Polar Flow holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: Polar Flow has 50K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Polar Flow's written reviews are positive against 100% of PaceShouter's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Polar Flow ships an update monthly, PaceShouter every 4 days. The most recent releases landed on October 17, 2026 and October 5, 2026 respectively.
