# C vs EarthScope

The clearest difference is review sentiment: C at 51% against EarthScope's 5%. C also leads on rating (4.5 vs 3.8) and ads (none vs shown). EarthScope's advantage is in-app purchases (none vs 11) and update cadence (fortnightly vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month. EarthScope asks for nothing beyond the download.

C holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 204, so its average is the more settled of the two. Written reviews point the same way: 51% of C's written reviews are positive against 5% of EarthScope's.

C ships an update every 6 weeks, EarthScope fortnightly. The most recent releases landed on September 29, 2026 and September 28, 2026 respectively.
