Verdict
The clearest difference is review sentiment: Zachet at 86% against mb4reader's 12%. Zachet also leads on rating (4.5 vs 2.3) and update cadence (every 4 days vs fortnightly). mb4reader's advantage is in-app purchases (none vs 4) and iOS requirement (8.2 vs 17.0). On price, ads and device support there is nothing between them.

Zachet holds the better App Store score, 4.5 against 2.3.

mb4reader ships an update fortnightly, Zachet every 4 days. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
