# Upside Down vs Deepfall

The clearest difference is rating: Upside Down at 4.6 against Deepfall's 3.1. Upside Down also leads on ratings volume (100 vs 8) and monetization model (ad-supported vs free with in-app purchases). Deepfall's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Upside Down sells 10 one-off in-app purchases and Deepfall sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Upside Down holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: Upside Down has 100 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 36% of Upside Down's written reviews are positive against 25% of Deepfall's.

Upside Down ships an update every 6 weeks, Deepfall every 2 weeks. The most recent releases landed on September 23, 2026 and August 15, 2026 respectively.
