DeskFlex holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: CRSI Rebar Reference has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of CRSI Rebar Reference's written reviews are positive against 0% of DeskFlex's, so the app with the better star average is not the one people write more warmly about.
CRSI Rebar Reference ships an update every 5 weeks, DeskFlex monthly. Both last shipped on June 1, 2026.
