# HOSFU vs RateTracker

The clearest difference is rating: RateTracker at 4.1 against HOSFU's 2.0. RateTracker also leads on ratings volume (5.7K vs 4) and update cadence (every 10 days vs monthly). HOSFU's advantage is in-app purchases (none vs 9) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. RateTracker sells 6 in-app purchases, starting at $6.99 per 7 days. HOSFU asks for nothing beyond the download.

RateTracker holds the better App Store score, 4.1 against 2.0. That said, the two scores are not equally well evidenced: RateTracker has 5.7K ratings behind it against 4, so its average is the more settled of the two.

HOSFU ships an update monthly, RateTracker every 10 days. The most recent releases landed on November 4, 2026 and November 7, 2026 respectively.
