# HistoGrams⁺ vs Microscope AI

The clearest difference is in-app purchases: HistoGrams⁺ at none against Microscope AI's 3. HistoGrams⁺ also leads on rating (4.7 vs 4.3) and iOS requirement (12.0 vs 15.1). Microscope AI's advantage is review sentiment (100% vs 67%) and update cadence (monthly vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. Microscope AI sells 3 in-app purchases, starting at $5.99 per 7 days. HistoGrams⁺ asks for nothing beyond the download.

HistoGrams⁺ holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 3 and 14 respectively. Written reviews complicate that: 67% of HistoGrams⁺'s written reviews are positive against 100% of Microscope AI's, so the app with the better star average is not the one people write more warmly about.

HistoGrams⁺ ships an update every 2 months, Microscope AI monthly. The most recent releases landed on October 9, 2026 and October 6, 2026 respectively.
