ReceptionRating · Positive reviews · Number of ratings

STEM Wizard Form Uploader holds the better App Store score, 3.7 against 1.9. That said, the two scores are not equally well evidenced: SPARKvue 4 has 638 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 46% of SPARKvue 4's written reviews are positive against 33% of STEM Wizard Form Uploader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SPARKvue 4 ships an update every 2 months, STEM Wizard Form Uploader every 5 weeks. The most recent releases landed on September 27, 2026 and June 1, 2026 respectively.
