# ErgData vs Staka

The clearest difference is review sentiment: Staka at 100% against ErgData's 47%. Staka also leads on rating (5.0 vs 4.7). ErgData's advantage is ratings volume (6.3K vs 6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Staka holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ErgData has 6.3K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 47% of ErgData's written reviews are positive against 100% of Staka's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
