Verdict
The clearest difference is review sentiment: Silarius at 100% against GSM's 17%. Silarius also leads on rating (4.8 vs 2.3) and ratings volume (18 vs 3). GSM's advantage is iOS requirement (7.0 vs 15.0). On price, update cadence, ads and in-app purchases 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.
Silarius holds the better App Store score, 4.8 against 2.3. That said, the two scores are not equally well evidenced: Silarius has 18 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 17% of GSM's written reviews are positive against 100% of Silarius's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
