# RadarScope vs Tempest Weather

The clearest difference is price: Tempest Weather at Free against RadarScope's $9.99. Tempest Weather also leads on in-app purchases (none vs 4) and update cadence (every 8 days vs monthly). RadarScope's advantage is rating (4.2 vs 3.9) and chart position (#1 vs #138). On ads, device support and iOS requirement there is nothing between them.

Tempest Weather is free to download; RadarScope costs $9.99 up front. RadarScope sells 4 in-app purchases, starting at $9.99 per year. Tempest Weather asks for nothing beyond the download.

RadarScope holds the better App Store score, 4.2 against 3.9. That said, the two scores are not equally well evidenced: RadarScope has 2.8K ratings behind it against 504, so its average is the more settled of the two. Written reviews complicate that: 51% of RadarScope's written reviews are positive against 60% of Tempest Weather's, so the app with the better star average is not the one people write more warmly about.

RadarScope ships an update monthly, Tempest Weather every 8 days. Both last shipped on November 6, 2026.
