# SynthMaster Player vs Factory

The clearest difference is rating: Factory at 4.9 against SynthMaster Player's 4.4. Factory also leads on review sentiment (81% vs 52%) and ratings volume (487 vs 55). SynthMaster Player's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. SynthMaster Player sells 13 one-off in-app purchases and Factory sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Factory holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Factory has 487 ratings behind it against 55, so its average is the more settled of the two. Written reviews point the same way: 52% of SynthMaster Player's written reviews are positive against 81% of Factory's.

SynthMaster Player ships an update every 3 months, Factory every 4 months. The most recent releases landed on September 24, 2026 and August 12, 2026 respectively.
