# Secure Notes vs CalcPlus

The clearest difference is review sentiment: CalcPlus at 100% against Secure Notes's 65%. CalcPlus also leads on rating (5.0 vs 4.6). Secure Notes's advantage is ratings volume (719 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Secure Notes sells 6 in-app purchases, starting at $4.99 per month and CalcPlus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CalcPlus holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Secure Notes has 719 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 65% of Secure Notes's written reviews are positive against 100% of CalcPlus's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 14, 2026 and October 2, 2026 respectively.
