Verdict
The clearest difference is price: Pixii App at Free against Massive Dev Chart Timer's $9.99. Pixii App also leads on rating (4.0 vs 3.7) and update cadence (every 2 months vs every 5 months). Massive Dev Chart Timer's advantage is ratings volume (55 vs 5) and chart position (#56 vs unranked). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Pixii App is free to download; Massive Dev Chart Timer costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Pixii App holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Massive Dev Chart Timer has 55 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 71% of Massive Dev Chart Timer's written reviews are positive against 67% of Pixii App's, so the app with the better star average is not the one people write more warmly about.
Massive Dev Chart Timer ships an update every 5 months, Pixii App every 2 months. The most recent releases landed on October 18, 2026 and October 13, 2026 respectively.
