# Trace vs SnapCare

The clearest difference is rating: Trace at 4.6 against SnapCare's 3.0. Trace also leads on monetization model (free with in-app purchases vs subscription) and update cadence (daily vs every 4 weeks). SnapCare's advantage is ads (none vs shown). On price, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Trace sells 5 in-app purchases, starting at $4.99 per 7 days and SnapCare sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Trace holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Trace has 28 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 50% and 50% positive.

Trace ships an update daily, SnapCare every 4 weeks. The most recent releases landed on October 6, 2026 and October 11, 2026 respectively.
