# Stackr vs Titrate

The clearest difference is rating: Titrate at 5.0 against Stackr's 4.4. Titrate also leads on review sentiment (100% vs 67%) and iOS requirement (15.1 vs 17.0). Stackr's advantage is update cadence (every 4 days vs every 11 days) and ratings volume (191 vs 18). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stackr sells 7 in-app purchases, starting at $7.99 per 7 days and Titrate sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Titrate holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stackr has 191 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 67% of Stackr's written reviews are positive against 100% of Titrate's.

Stackr ships an update every 4 days, Titrate every 11 days. The most recent releases landed on October 25, 2026 and October 21, 2026 respectively.
