Verdict

The call

The clearest difference is price: PredictCurrent at Free against HF Weather Fax's $3.99. PredictCurrent also leads on rating (4.5 vs 3.7) and update cadence (monthly vs every 7 months). HF Weather Fax's advantage is in-app purchases (none vs 5) and review sentiment (73% vs 57%). On ads, chart position and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PredictCurrent holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: PredictCurrent has 255 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 73% of HF Weather Fax's written reviews are positive against 57% of PredictCurrent's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HF Weather Fax ships an update every 7 months, PredictCurrent monthly. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
