Verdict
The clearest difference is rating: ZiNote at 5.0 against SciSpace's 3.2. ZiNote also leads on iOS requirement (13.0 vs 15.1). SciSpace's advantage is in-app purchases (none vs 5) and update cadence (fortnightly vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. ZiNote sells 5 in-app purchases, starting at $4.99 per month. SciSpace asks for nothing beyond the download.
ZiNote holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: SciSpace has 6 ratings behind it against 1, so its average is the more settled of the two.
SciSpace ships an update fortnightly, ZiNote every 3 months. The most recent releases landed on October 9, 2026 and October 6, 2026 respectively.
