Verdict

The call

The clearest difference is update cadence: Lexia PowerUp at monthly against TestNav's every 8 months. Lexia PowerUp also leads on rating (2.0 vs 1.6) and ratings volume (874 vs 104). TestNav's advantage is review sentiment (24% vs 15%) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Lexia PowerUp holds the better App Store score, 2.0 against 1.6. That said, the two scores are not equally well evidenced: Lexia PowerUp has 874 ratings behind it against 104, so its average is the more settled of the two. Written reviews complicate that: 24% of TestNav's written reviews are positive against 15% of Lexia PowerUp's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TestNav ships an update every 8 months, Lexia PowerUp monthly. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
