# SilentLog vs Stockr (ストッカー)

The clearest difference is rating: SilentLog at 4.2 against Stockr (ストッカー)'s 3.0. SilentLog also leads on ads (none vs shown) and ratings volume (37 vs 1). Stockr (ストッカー)'s advantage is review sentiment (78% vs 41%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. SilentLog sells 3 one-off in-app purchases and Stockr (ストッカー) sells 13 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SilentLog holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: SilentLog has 37 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 41% of SilentLog's written reviews are positive against 78% of Stockr (ストッカー)'s, so the app with the better star average is not the one people write more warmly about.

SilentLog ships an update every 4 weeks, Stockr (ストッカー) fortnightly. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
