# SPARKvue 4 vs STEM Wizard Form Uploader

The clearest difference is rating: STEM Wizard Form Uploader at 3.7 against SPARKvue 4's 1.9. STEM Wizard Form Uploader also leads on update cadence (every 5 weeks vs every 2 months) and iOS requirement (9.0 vs 13.0). SPARKvue 4's advantage is ratings volume (638 vs 10) and review sentiment (46% vs 33%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.

SPARKvue 4 ships an update every 2 months, STEM Wizard Form Uploader every 5 weeks. The most recent releases landed on October 16, 2026 and October 2, 2026 respectively.
