# PULSE vs Skycatching

The clearest difference is in-app purchases: Skycatching at none against PULSE's 1. Skycatching also leads on update cadence (every 3 days vs weekly). PULSE's advantage is ratings volume (8 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. PULSE sells 1 one-off in-app purchase. Skycatching asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for PULSE against 5.0 for Skycatching.

PULSE ships an update weekly, Skycatching every 3 days. Both last shipped on October 31, 2026.
