# Cellular Synthesizer vs Gradient Synth

Cellular Synthesizer and Gradient Synth both sit at 4.6 stars, but that hides the real split: 63% of Gradient Synth's written reviews are positive against 38% of Cellular Synthesizer's. Gradient Synth also leads on ratings volume (54 vs 5). Cellular Synthesizer's advantage is iOS requirement (12.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Cellular Synthesizer sells 3 in-app purchases, starting at $1.99 per month and Gradient Synth sells 5 in-app purchases, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

Cellular Synthesizer holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Gradient Synth has 54 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 38% of Cellular Synthesizer's written reviews are positive against 63% of Gradient Synth's, so the app with the better star average is not the one people write more warmly about.

Cellular Synthesizer ships an update every 2 months, Gradient Synth monthly. The most recent releases landed on September 9, 2026 and September 18, 2026 respectively.
