Verdict
The clearest difference is rating: NebulaBuds at 4.4 against SayMi's 3.5. NebulaBuds also leads on ratings volume (16K vs 249). SayMi's advantage is in-app purchases (none vs 12). On price, review sentiment, update cadence and ads 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. NebulaBuds sells 10 one-off in-app purchases. SayMi asks for nothing beyond the download.
NebulaBuds holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: NebulaBuds has 16K ratings behind it against 249, so its average is the more settled of the two. Written reviews complicate that: 21% of NebulaBuds's written reviews are positive against 26% of SayMi's, so the app with the better star average is not the one people write more warmly about.
NebulaBuds ships an update every 2 weeks, SayMi weekly. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
