Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Nest Egg ships an update every 6 weeks, Calibre Sync weekly. Both last shipped on September 24, 2026.
