# HF Weather Fax vs PredictCurrent

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.

PredictCurrent is free to download; HF Weather Fax costs $3.99 up front. PredictCurrent sells 5 in-app purchases, starting at $15.00 per month. HF Weather Fax asks for nothing beyond the download.

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.

HF Weather Fax ships an update every 7 months, PredictCurrent monthly. The most recent releases landed on October 18, 2026 and October 16, 2026 respectively.
