# 音频变调 vs Location

The clearest difference is in-app purchases: 音频变调 at none against Location's 1. Location's advantage is ads (none vs shown) and update cadence (every 4 days vs every 6 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Location sells 1 in-app purchase, starting at $4.99 per year. 音频变调 asks for nothing beyond the download.

音频变调 ships an update every 6 months, Location every 4 days. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
