# KW3 vs SoundLab

The clearest difference is rating: SoundLab at 4.6 against KW3's 4.0. SoundLab also leads on ads (none vs shown) and update cadence (weekly vs every 3 months). KW3's advantage is in-app purchases (none vs 3). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. SoundLab sells 3 in-app purchases, starting at $3.99 per month. KW3 asks for nothing beyond the download.

SoundLab holds the better App Store score, 4.6 against 4.0.
