# ElbowData vs Arc+

The clearest difference is rating: Arc+ at 4.6 against ElbowData's 3.0. Arc+ also leads on ads (none vs shown) and ratings volume (113 vs 2). ElbowData's advantage is review sentiment (75% vs 50%). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. ElbowData sells 1 one-off in-app purchase and Arc+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Arc+ holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Arc+ has 113 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of ElbowData's written reviews are positive against 50% of Arc+'s, so the app with the better star average is not the one people write more warmly about.

ElbowData ships an update every 2 months, Arc+ every 4 months. Both last shipped on September 22, 2026.
