Verdict
The clearest difference is rating: Nest Egg at 4.4 against Calibre Sync's 3.9. Nest Egg also leads on ratings volume (615 vs 54) and chart position (#193 vs unranked). Calibre Sync's advantage is in-app purchases (none vs 7) and update cadence (weekly vs every 6 weeks). On ads and device support there is nothing between them.

Nest Egg costs $6.99 and Calibre Sync $4.99 up front. Nest Egg sells 7 one-off in-app purchases. Calibre Sync asks for nothing beyond the download.
Nest Egg holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Nest Egg has 615 ratings behind it against 54, so its average is the more settled of the two. Written reviews complicate that: 54% of Nest Egg's written reviews are positive against 62% of Calibre Sync's, so the app with the better star average is not the one people write more warmly about.
Nest Egg ships an update every 6 weeks, Calibre Sync weekly. Both last shipped on September 24, 2026.
