# RISE vs zZz

The clearest difference is review sentiment: RISE at 49% against zZz's 0%. RISE also leads on rating (4.7 vs 2.9) and ratings volume (73K vs 11). zZz's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. RISE sells 10 in-app purchases, starting at $9.99 per month and zZz sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

RISE holds the better App Store score, 4.7 against 2.9. That said, the two scores are not equally well evidenced: RISE has 73K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 49% of RISE's written reviews are positive against 0% of zZz's.

RISE ships an update every 2 days, zZz every 4 days. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
