# UNK vs Stoolio

The clearest difference is review sentiment: Stoolio at 100% against UNK's 33%. Stoolio also leads on update cadence (weekly vs every 9 months) and ratings volume (7 vs 1). UNK's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 2). On price and device support there is nothing between them.

Both are free to download. Stoolio sells 2 in-app purchases, starting at $9.99 per month. UNK asks for nothing beyond the download.

UNK holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stoolio has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of UNK's written reviews are positive against 100% of Stoolio's, so the app with the better star average is not the one people write more warmly about.

UNK ships an update every 9 months, Stoolio weekly. The most recent releases landed on October 7, 2026 and October 24, 2026 respectively.
