# Core Synth Free vs Synth Pro

The clearest difference is rating: Synth Pro at 4.6 against Core Synth Free's 2.9. Synth Pro also leads on update cadence (monthly vs every 13 months) and ratings volume (555 vs 8). Core Synth Free's advantage is ads (none vs shown) and iOS requirement (8.0 vs 18.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Core Synth Free sells 1 one-off in-app purchase and Synth Pro sells 20 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Synth Pro holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: Synth Pro has 555 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 64% of Core Synth Free's written reviews are positive against 71% of Synth Pro's.

Core Synth Free ships an update every 13 months, Synth Pro monthly. The most recent releases landed on October 20, 2026 and October 30, 2026 respectively.
