ReceptionRating · Positive reviews · Number of ratings

stashcat holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: NetSfere Secure Messaging has 115 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 93% of NetSfere Secure Messaging's written reviews are positive against 50% of stashcat's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NetSfere Secure Messaging ships an update every 2 months, stashcat fortnightly. The most recent releases landed on September 7, 2026 and September 10, 2026 respectively.
