# 百度 vs 51车联

The clearest difference is in-app purchases: 51车联 at none against 百度's 12. 51车联 also leads on ads (none vs shown). 百度's advantage is update cadence (weekly vs every 4 weeks) and device support (4 vs 2). On price there is nothing between them.

Both are free to download. 百度 sells 12 in-app purchases, starting at $1.99 per month. 51车联 asks for nothing beyond the download.

百度 ships an update weekly, 51车联 every 4 weeks. The most recent releases landed on September 25, 2026 and September 2, 2026 respectively.
