# サイゾーまとめ vs iM

The clearest difference is rating: iM at 5.0 against サイゾーまとめ's 4.0. iM also leads on ads (none vs shown) and update cadence (monthly vs every 6 months). サイゾーまとめ's advantage is review sentiment (71% vs 31%). On price, ratings volume, 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.

iM holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 71% of サイゾーまとめ's written reviews are positive against 31% of iM's, so the app with the better star average is not the one people write more warmly about.

サイゾーまとめ ships an update every 6 months, iM monthly. The most recent releases landed on October 23, 2026 and October 19, 2026 respectively.
