# 挚达 vs i记

The clearest difference is ads: i记 at none against 挚达's shown. i记 also leads on update cadence (every 2 days vs every 3 weeks). 挚达's advantage is iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

挚达 ships an update every 3 weeks, i记 every 2 days. The most recent releases landed on October 10, 2026 and September 29, 2026 respectively.
