# Sherlock vs Watson

The clearest difference is rating: Watson at 4.6 against Sherlock's 2.0. Watson also leads on ratings volume (13 vs 4). Sherlock's advantage is update cadence (every 5 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sherlock sells 2 in-app purchases, starting at $6.99 per 7 days and Watson sells 7 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Watson holds the better App Store score, 4.6 against 2.0. Both are backed by a comparable volume of ratings — 4 and 13 respectively.

Sherlock ships an update every 5 days, Watson monthly. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
