# Elbow vs ElbowCalc

The clearest difference is rating: Elbow at 5.0 against ElbowCalc's 4.3. ElbowCalc's advantage is update cadence (every 5 weeks vs every 4 months) and ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Elbow sells 2 in-app purchases, starting at $4.99 per 7 days and ElbowCalc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Elbow holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: ElbowCalc has 7 ratings behind it against 1, so its average is the more settled of the two.

Elbow ships an update every 4 months, ElbowCalc every 5 weeks. The most recent releases landed on September 7, 2026 and September 10, 2026 respectively.
