# Zults vs ROXFIT

The clearest difference is rating: ROXFIT at 4.8 against Zults's 4.3. ROXFIT also leads on update cadence (every 4 days vs every 3 weeks) and monetization model (free vs freemium). Zults's advantage is review sentiment (100% vs 83%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Zults sells 2 in-app purchases, starting at $1.99 per month and ROXFIT sells 5 in-app purchases, starting at $15.99 per month. Whichever you choose, the download price is not the number that matters.

ROXFIT holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: ROXFIT has 4.5K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of Zults's written reviews are positive against 83% of ROXFIT's, so the app with the better star average is not the one people write more warmly about.

Zults ships an update every 3 weeks, ROXFIT every 4 days. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
