# iMMIG vs 國泰證券

The clearest difference is ads: iMMIG at none against 國泰證券's shown. iMMIG also leads on iOS requirement (9.0 vs 15.0). 國泰證券's advantage is update cadence (weekly vs every 2 months) and rating (4.9 vs 4.5). On price, review sentiment, 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.

國泰證券 holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: 國泰證券 has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

iMMIG ships an update every 2 months, 國泰證券 weekly. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
