# Fastin vs HD Pro

The clearest difference is monetization model: HD Pro at free with in-app purchases against Fastin's subscription. HD Pro also leads on iOS requirement (14.0 vs 16.6). Fastin's advantage is ratings volume (10K vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Fastin sells 10 in-app purchases, starting at $4.49 per 7 days and HD Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

HD Pro holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Fastin has 10K ratings behind it against 1, so its average is the more settled of the two.

Fastin ships an update every 3 weeks, HD Pro every 2 weeks. The most recent releases landed on November 1, 2026 and October 27, 2026 respectively.
