Verdict

The call

The clearest difference is review sentiment: Psychflex at 100% against PESI's 14%. Psychflex also leads on in-app purchases (none vs 8). PESI's advantage is rating (4.7 vs 4.0) and update cadence (fortnightly vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. PESI sells 7 one-off in-app purchases. Psychflex asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

PESI holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: PESI has 3.5K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 14% of PESI's written reviews are positive against 100% of Psychflex's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PESI ships an update fortnightly, Psychflex every 4 months. The most recent releases landed on October 19, 2026 and September 22, 2026 respectively.
