# InTune vs HD

The clearest difference is price: HD at Free against InTune's $0.99. HD also leads on in-app purchases (none vs 14) and rating (5.0 vs 4.7). InTune's advantage is ratings volume (558 vs 3) and update cadence (every 3 months vs every 10 months). On ads, device support and iOS requirement there is nothing between them.

HD is free to download; InTune costs $0.99 up front. InTune sells 13 one-off in-app purchases. HD asks for nothing beyond the download.

HD holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: InTune has 558 ratings behind it against 3, so its average is the more settled of the two.

InTune ships an update every 3 months, HD every 10 months. The most recent releases landed on November 1, 2026 and October 22, 2026 respectively.
