# 懒人驾考 vs i

The clearest difference is in-app purchases: i at none against 懒人驾考's 4. i also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.6). 懒人驾考's advantage is update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.

懒人驾考 ships an update every 2 weeks, i every 2 months. The most recent releases landed on September 15, 2026 and June 20, 2026 respectively.
