# Histograms Explained vs Photo Expert

The clearest difference is review sentiment: Histograms Explained at 50% against Photo Expert's 5%. Histograms Explained also leads on in-app purchases (none vs 7) and ads (none vs shown). Photo Expert's advantage is price (Free vs $4.99) and rating (4.4 vs 3.3). On device support there is nothing between them.

Photo Expert is free to download; Histograms Explained costs $4.99 up front. Photo Expert sells 7 in-app purchases, starting at $3.49 per 7 days. Histograms Explained asks for nothing beyond the download.

Photo Expert holds the better App Store score, 4.4 against 3.3. That said, the two scores are not equally well evidenced: Photo Expert has 120 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of Histograms Explained's written reviews are positive against 5% of Photo Expert's, so the app with the better star average is not the one people write more warmly about.

Histograms Explained ships an update every 40 months, Photo Expert every 9 days. The most recent releases landed on October 15, 2026 and October 22, 2026 respectively.
