# Ruler® vs Flip a Coin App

The clearest difference is review sentiment: Flip a Coin App at 66% against Ruler®'s 22%. Flip a Coin App also leads on rating (4.6 vs 4.3). Ruler®'s advantage is ads (none vs shown) and ratings volume (35K vs 3.4K). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Ruler® sells 2 in-app purchases, starting at $1.99 per 7 days and Flip a Coin App sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Flip a Coin App holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Ruler® has 35K ratings behind it against 3.4K, so its average is the more settled of the two.
