# HeitzFit 4 vs ESS Boost

The clearest difference is review sentiment: ESS Boost at 100% against HeitzFit 4's 8%. ESS Boost also leads on update cadence (every 6 days vs every 2 months) and ratings volume (22 vs 1). HeitzFit 4's advantage is rating (5.0 vs 4.5) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HeitzFit 4 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: ESS Boost has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 8% of HeitzFit 4's written reviews are positive against 100% of ESS Boost's, so the app with the better star average is not the one people write more warmly about.

HeitzFit 4 ships an update every 2 months, ESS Boost every 6 days. The most recent releases landed on October 20, 2026 and October 11, 2026 respectively.
