Verdict

The call

The clearest difference is price: Focus Chart at Free against pCAM Pro's $34.99. Focus Chart also leads on in-app purchases (none vs 3) and iOS requirement (12.0 vs 17.0). pCAM Pro's advantage is rating (4.9 vs 4.4) and update cadence (weekly vs every 16 months). On review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

pCAM Pro holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: pCAM Pro has 222 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Focus Chart's written reviews are positive against 97% of pCAM Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Focus Chart ships an update every 16 months, pCAM Pro weekly. The most recent releases landed on October 4, 2026 and October 12, 2026 respectively.
