# SPACE vs 53Hz

SPACE and 53Hz both sit at 3.9 stars, but that hides the real split: 100% of 53Hz's written reviews are positive against 51% of SPACE's. 53Hz also leads on update cadence (every 2 days vs every 3 weeks). SPACE's advantage is ratings volume (45 vs 2) and iOS requirement (14.0 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. SPACE sells 4 in-app purchases, starting at $3.99 per 3 months and 53Hz sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 3.9 for SPACE against 4.0 for 53Hz. That said, the two scores are not equally well evidenced: SPACE has 45 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 51% of SPACE's written reviews are positive against 100% of 53Hz's.

SPACE ships an update every 3 weeks, 53Hz every 2 days. The most recent releases landed on October 14, 2026 and October 3, 2026 respectively.
