Verdict
The clearest difference is rating: WattUp at 4.2 against Code's 1.0. WattUp also leads on update cadence (every 5 weeks vs every 8 months) and ratings volume (5 vs 1). Code's advantage is review sentiment (25% vs 0%) and iOS requirement (11 vs 18.6). 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.
WattUp holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: WattUp has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Code's written reviews are positive against 0% of WattUp's, so the app with the better star average is not the one people write more warmly about.
Code ships an update every 8 months, WattUp every 5 weeks. Both last shipped on November 3, 2026.
