# REAPPLY vs SunSync

The clearest difference is rating: SunSync at 4.5 against REAPPLY's 3.4. SunSync also leads on update cadence (fortnightly vs monthly) and device support (3 vs 1). REAPPLY's advantage is in-app purchases (none vs 2) and ratings volume (33 vs 4). On price, review sentiment, ads and iOS requirement there is nothing between them.

Both are free to download. SunSync sells 2 in-app purchases, starting at $1.99 per month. REAPPLY asks for nothing beyond the download.

SunSync holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: REAPPLY has 33 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 52% of REAPPLY's written reviews are positive against 50% of SunSync's, so the app with the better star average is not the one people write more warmly about.

REAPPLY ships an update monthly, SunSync fortnightly. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
