# 火星 vs DD星球

The clearest difference is review sentiment: DD星球 at 100% against 火星's 56%. DD星球 also leads on rating (5.0 vs 3.5) and ads (none vs shown). 火星's advantage is ratings volume (91 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 火星 sells 20 in-app purchases, starting at $0.99 per month and DD星球 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DD星球 holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: 火星 has 91 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 56% of 火星's written reviews are positive against 100% of DD星球's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 15, 2026 and September 8, 2026 respectively.
