# Big Billy vs Shape Rhythm

The clearest difference is ads: Big Billy at none against Shape Rhythm's shown. Shape Rhythm's advantage is update cadence (every 7 months vs every 20 months) and iOS requirement (12.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Big Billy sells 1 one-off in-app purchase and Shape Rhythm sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Big Billy ships an update every 20 months, Shape Rhythm every 7 months. The most recent releases landed on October 1, 2026 and October 16, 2026 respectively.
