# Sunlight Clock Free vs SpaceWeatherLive

The clearest difference is in-app purchases: Sunlight Clock Free at none against SpaceWeatherLive's 3. Sunlight Clock Free also leads on ads (none vs shown) and review sentiment (74% vs 53%). SpaceWeatherLive's advantage is rating (4.0 vs 3.7) and update cadence (every 4 months vs every 18 months). On price and device support there is nothing between them.

Both are free to download. SpaceWeatherLive sells 3 in-app purchases, starting at $0.99 per month. Sunlight Clock Free asks for nothing beyond the download.

SpaceWeatherLive holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: SpaceWeatherLive has 189 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 74% of Sunlight Clock Free's written reviews are positive against 53% of SpaceWeatherLive's, so the app with the better star average is not the one people write more warmly about.

Sunlight Clock Free ships an update every 18 months, SpaceWeatherLive every 4 months. The most recent releases landed on October 15, 2026 and October 19, 2026 respectively.
