Verdict
The clearest difference is rating: Mi MCS at 4.5 against NaturalSlim's 4.2. Mi MCS also leads on ratings volume (3.4K vs 45) and update cadence (every 4 months vs every 8 months). NaturalSlim's advantage is review sentiment (38% vs 22%) and iOS requirement (7.0 vs 12.2). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Mi MCS holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Mi MCS has 3.4K ratings behind it against 45, so its average is the more settled of the two. Written reviews complicate that: 38% of NaturalSlim's written reviews are positive against 22% of Mi MCS's, so the app with the better star average is not the one people write more warmly about.
NaturalSlim ships an update every 8 months, Mi MCS every 4 months. Both last shipped on October 24, 2026.
