Pulse Oxygen Level : Lung Test

Ranks #1 for "pulse oxygen level", #4 for "oxygen saturation", #5 for "oxygen level tracker" and #6 for "blood oxygen tracker", covering 4 of the top 10 target keywords with an 81% keyword score.

Charts Score is 0%, meaning the listing lacks screenshots or video. This drags down the Quality Score (63%) and reduces conversion rates on the store.

A 3.0‑star rating from only 37 reviews hurts credibility and the Quality Score, likely contributing to the lack of category ranking.

Keywords such as "heart rate monitor" (traffic 69, difficulty 78) and "pulse tracker" (traffic 46, difficulty 37) are not ranked. Adding these terms to title, short description, and in‑app copy can capture additional search volume.

The app is not ranked in the Health & Fitness category despite ranking for related terms like "lung health monitor" (rank 26) and "lung function test" (rank 10). Optimizing category‑specific metadata and adding category‑relevant keywords can unlock category chart placement.
