Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

InstaSub holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: InstaSub has 241 ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 0% of InstaSub's written reviews are positive against 65% of Senya's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

InstaSub ships an update every 6 weeks, Senya every 2 weeks. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
