# Spyglass vs Celestial Nav

The clearest difference is ads: Celestial Nav at none against Spyglass's shown. Spyglass's advantage is rating (4.7 vs 4.3) and ratings volume (3.9K vs 10). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spyglass sells 4 in-app purchases, starting at $3.99 per month and Celestial Nav sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Spyglass holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Spyglass has 3.9K ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 80% of Spyglass's written reviews are positive against 58% of Celestial Nav's.

Spyglass ships an update every 6 weeks, Celestial Nav every 3 weeks. The most recent releases landed on September 25, 2026 and September 13, 2026 respectively.
