# OLED Clock vs METH

The clearest difference is review sentiment: OLED Clock at 79% against METH's 0%. OLED Clock also leads on ratings volume (15 vs 1) and iOS requirement (12.0 vs 14.0.0). METH's advantage is rating (5.0 vs 3.9) and update cadence (every 4 days vs every 4 weeks). 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.

METH holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: OLED Clock has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of OLED Clock's written reviews are positive against 0% of METH's, so the app with the better star average is not the one people write more warmly about.

OLED Clock ships an update every 4 weeks, METH every 4 days. The most recent releases landed on October 7, 2026 and October 4, 2026 respectively.
