# 体检指标解读 vs 头发呢

The clearest difference is in-app purchases: 体检指标解读 at none against 头发呢's 3. 头发呢's advantage is ads (none vs shown) and update cadence (every 3 days vs every 12 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 头发呢 sells 3 in-app purchases, starting at $3.99 per month. 体检指标解读 asks for nothing beyond the download.

体检指标解读 ships an update every 12 months, 头发呢 every 3 days. The most recent releases landed on October 26, 2026 and October 28, 2026 respectively.
