# Atomic Clock PRO vs FlagBot

The clearest difference is review sentiment: Atomic Clock PRO at 73% against FlagBot's 14%. Atomic Clock PRO also leads on rating (4.7 vs 1.6) and ratings volume (10K vs 18). FlagBot's advantage is ads (none vs shown) and update cadence (every 10 days vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Atomic Clock PRO sells 2 in-app purchases, starting at $1.99 per month and FlagBot sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
