The clearest difference is in-app purchases: Flux Mini 2 at none against Synth Pro's 10. Flux Mini 2 also leads on ads (none vs shown) and rating (4.8 vs 4.6). Synth Pro's advantage is ratings volume (557 vs 35). On price, review sentiment and device support there is nothing between them.

Both are free to download. Synth Pro sells 10 in-app purchases, starting at $5.99 per month. Flux Mini 2 asks for nothing beyond the download.

Flux Mini 2 holds the better App Store score, 4.8 against 4.6.
