# Mathe Alarm Clock vs Pool Math by TroubleFreePool

The clearest difference is rating: Mathe Alarm Clock at 4.5 against Pool Math by TroubleFreePool's 3.6. Mathe Alarm Clock also leads on ratings volume (8.5K vs 287) and iOS requirement (13.0 vs 15.0). Pool Math by TroubleFreePool's advantage is ads (none vs shown) and update cadence (fortnightly vs every 5 weeks).

Both are free to download. Mathe Alarm Clock sells 1 one-off in-app purchase and Pool Math by TroubleFreePool sells 1 in-app purchase, starting at $7.99 per year. Whichever you choose, the download price is not the number that matters.

Mathe Alarm Clock holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Mathe Alarm Clock has 8.5K ratings behind it against 287, so its average is the more settled of the two. Written reviews complicate that: 57% of Mathe Alarm Clock's written reviews are positive against 63% of Pool Math by TroubleFreePool's, so the app with the better star average is not the one people write more warmly about.
