Verdict
The clearest difference is price: DTE PedalBox at Free against JB4 Mobile's $27.99. DTE PedalBox also leads on rating (4.2 vs 3.8). JB4 Mobile's advantage is ratings volume (239 vs 6) and chart position (#7 vs unranked). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

DTE PedalBox is free to download; JB4 Mobile costs $27.99 up front. Neither carries in-app purchases, so what you see is what you pay.
DTE PedalBox holds the better App Store score, 4.2 against 3.8. That said, the two scores are not equally well evidenced: JB4 Mobile has 239 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 52% of JB4 Mobile's written reviews are positive against 50% of DTE PedalBox's, so the app with the better star average is not the one people write more warmly about.
JB4 Mobile ships an update every 3 months, DTE PedalBox every 5 months. The most recent releases landed on October 19, 2026 and October 14, 2026 respectively.
