# Voltage Divider vs Hacker Clock

The clearest difference is rating: Hacker Clock at 4.5 against Voltage Divider's 2.7. Hacker Clock also leads on update cadence (every 15 months vs every 48 months) and ratings volume (41 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.

Voltage Divider costs $1.99 and Hacker Clock $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Hacker Clock holds the better App Store score, 4.5 against 2.7. That said, the two scores are not equally well evidenced: Hacker Clock has 41 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of Voltage Divider's written reviews are positive against 54% of Hacker Clock's, so the app with the better star average is not the one people write more warmly about.

Voltage Divider ships an update every 48 months, Hacker Clock every 15 months. The most recent releases landed on June 23, 2026 and September 25, 2026 respectively.
