# Laser Harp vs spool.

The clearest difference is ads: spool. at none against Laser Harp's shown. Laser Harp's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Laser Harp sells 1 one-off in-app purchase and spool. sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
