ECG Analysis for Polar H10

Eight out of ten target keywords rank on the first page, including "ecg analysis" (rank 1), "ecg sensor" (rank 1), and "polar h10" (rank 3), driving a combined traffic potential of over 250 searches per month.

The Quality Score is 53% and the app holds a 3.1‑star rating from 253 reviews, indicating poor conversion and retention; this directly suppresses chart rankings and category placement.

Charts Score is 0% (global and category charts not ranked), meaning the app is not appearing in trending or top‑list placements that drive organic installs.

High‑traffic keywords such as "heart rate tracker" (traffic 47) and "cardiac rehabilitation" (traffic 39) are currently unranked. Incorporating them naturally into the short description, long description, and UI copy can capture additional search volume.

Adding 5+ high‑resolution screenshots, a 30‑second feature video, and localized graphics aligns with top‑ranking competitors and can improve the Charts Score and conversion rate.

Implementing timely in‑app review prompts and addressing common complaints (as identified in the 253 reviews) can raise the average rating to >4.0, which is critical for category ranking and algorithmic trust.
