# Tuner vs 准音

The clearest difference is in-app purchases: 准音 at none against Tuner's 1. Tuner's advantage is device support (3 vs 1) and iOS requirement (13 vs 18.5). On price and ads there is nothing between them.

Both are free to download. Tuner sells 1 one-off in-app purchase. 准音 asks for nothing beyond the download.
