# 北斗AR地球仪 vs 数感星球

The clearest difference is review sentiment: 数感星球 at 92% against 北斗AR地球仪's 40%. 数感星球 also leads on rating (4.5 vs 3.0) and update cadence (fortnightly vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 北斗AR地球仪 sells 1 one-off in-app purchase and 数感星球 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
