# Logic Puzzles vs FireLine

Logic Puzzles and FireLine both sit at 4.6 stars, but that hides the real split: 63% of Logic Puzzles's written reviews are positive against 38% of FireLine's. Logic Puzzles also leads on update cadence (every 9 days vs every 3 weeks). FireLine's advantage is ratings volume (531 vs 71) and iOS requirement (12.0 vs 15.6).

Both are free to download. Logic Puzzles sells 12 in-app purchases, starting at $1.99 per month and FireLine sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: FireLine has 531 ratings behind it against 71, so its average is the more settled of the two.
