# Injectly vs PepLog

The clearest difference is in-app purchases: Injectly at none against PepLog's 2. Injectly also leads on rating (4.8 vs 4.4) and ratings volume (507 vs 26). PepLog's advantage is review sentiment (100% vs 87%). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. PepLog sells 2 in-app purchases, starting at $9.99 per month. Injectly asks for nothing beyond the download.

Injectly holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Injectly has 507 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 87% of Injectly's written reviews are positive against 100% of PepLog's, so the app with the better star average is not the one people write more warmly about.

Injectly ships an update every 2 weeks, PepLog fortnightly. The most recent releases landed on November 12, 2026 and November 10, 2026 respectively.
