# 测距测量仪 vs 仪表宝典

The clearest difference is ads: 测距测量仪 at none against 仪表宝典's shown. 仪表宝典's advantage is update cadence (every 3 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 测距测量仪 sells 4 one-off in-app purchases and 仪表宝典 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

测距测量仪 ships an update every 2 months, 仪表宝典 every 3 days. The most recent releases landed on October 7, 2026 and October 5, 2026 respectively.
