The clearest difference is in-app purchases: VR MemoPa at none against Dual N's 2. VR MemoPa also leads on update cadence (every 10 days vs every 3 weeks).

Both are free to download. Dual N sells 2 in-app purchases, starting at $0.99 per month. VR MemoPa asks for nothing beyond the download.

Dual N holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Dual N has 1.2K ratings behind it against 2, so its average is the more settled of the two.
