# Date T Calc vs Noteflow

Date T Calc and Noteflow both sit at 4.0 stars, but that hides the real split: 100% of Date T Calc's written reviews are positive against 47% of Noteflow's. Noteflow's advantage is price (Free vs $0.99) and update cadence (every 6 weeks vs every 17 months). On rating, ads, in-app purchases and device support there is nothing between them.

Noteflow is free to download; Date T Calc costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Noteflow holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Noteflow has 184 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Date T Calc's written reviews are positive against 47% of Noteflow's, so the app with the better star average is not the one people write more warmly about.

Date T Calc ships an update every 17 months, Noteflow every 6 weeks. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
