# StrengthMark vs Intensity

The clearest difference is in-app purchases: StrengthMark at none against Intensity's 3. StrengthMark also leads on review sentiment (92% vs 64%) and iOS requirement (13.0 vs 15.6). Intensity's advantage is update cadence (every 4 weeks vs every 3 months) and ratings volume (180 vs 15). On price, rating and ads there is nothing between them.

Both are free to download. Intensity sells 3 in-app purchases, starting at $2.99 per month. StrengthMark asks for nothing beyond the download.

StrengthMark holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Intensity has 180 ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 92% of StrengthMark's written reviews are positive against 64% of Intensity's.

StrengthMark ships an update every 3 months, Intensity every 4 weeks. The most recent releases landed on October 12, 2026 and October 17, 2026 respectively.
