Verdict
The clearest difference is in-app purchases: Inner Matrix Systems at none against MoodMail's 1. Inner Matrix Systems also leads on ratings volume (23 vs 2) and device support (3 vs 1). MoodMail's advantage is rating (5.0 vs 4.7). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. MoodMail sells 1 one-off in-app purchase. Inner Matrix Systems asks for nothing beyond the download.
MoodMail holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Inner Matrix Systems has 23 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.
Both ship on a similar rhythm, roughly every 6 months. Both last shipped on September 29, 2026.
