# Physics vs QuantumNote

The clearest difference is in-app purchases: QuantumNote at none against Physics's 4. QuantumNote also leads on rating (5.0 vs 4.7). Physics's advantage is ratings volume (18 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Physics sells 4 in-app purchases, starting at $1.99 per month. QuantumNote asks for nothing beyond the download.

QuantumNote holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Physics has 18 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 1, 2026 and September 27, 2026 respectively.
