# Clock vs Shift Work Alarm

The clearest difference is rating: Shift Work Alarm at 5.0 against Clock's 3.4. Shift Work Alarm also leads on ads (none vs shown) and update cadence (every 9 days vs every 2 months). Clock's advantage is ratings volume (7 vs 1) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Clock sells 2 in-app purchases, starting at $1.99 per month and Shift Work Alarm sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Shift Work Alarm holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Clock has 7 ratings behind it against 1, so its average is the more settled of the two.
