# Exam Timer vs Hachi

The clearest difference is in-app purchases: Exam Timer at none against Hachi's 1. Exam Timer also leads on update cadence (every 2 months vs every 3 months) and iOS requirement (13.0 vs 16.4). Hachi's advantage is ads (none vs shown) and review sentiment (100% vs 75%). On price and device support there is nothing between them.

Both are free to download. Hachi sells 1 one-off in-app purchase. Exam Timer asks for nothing beyond the download.

Exam Timer ships an update every 2 months, Hachi every 3 months. The most recent releases landed on September 16, 2026 and August 19, 2026 respectively.
