# Sincerely vs SleighSync

The clearest difference is ratings volume: Sincerely at 36K against SleighSync's 1. Sincerely also leads on chart position (#98 vs unranked) and iOS requirement (16.6 vs 18.6). SleighSync's advantage is rating (5.0 vs 4.7) and update cadence (every 6 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sincerely sells 19 in-app purchases, starting at $4.99 per month and SleighSync sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SleighSync holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sincerely has 36K ratings behind it against 1, so its average is the more settled of the two.

Sincerely ships an update every 2 weeks, SleighSync every 6 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
