Verdict
The clearest difference is in-app purchases: Sollah Library at none against Electrical Components Quiz's 4. Sollah Library also leads on update cadence (monthly vs every 12 months) and device support (3 vs 1). Electrical Components Quiz's advantage is ads (none vs shown) and ratings volume (6 vs 1). On price and rating there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Electrical Components Quiz sells 4 in-app purchases, starting at $7.99 per 7 days. Sollah Library asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 5.0 for Sollah Library against 5.0 for Electrical Components Quiz. That said, the two scores are not equally well evidenced: Electrical Components Quiz has 6 ratings behind it against 1, so its average is the more settled of the two.
Sollah Library ships an update monthly, Electrical Components Quiz every 12 months. The most recent releases landed on June 24, 2026 and June 3, 2026 respectively.
