# Zing Sessions vs FocusCurve

The clearest difference is rating: FocusCurve at 4.0 against Zing Sessions's 2.9. FocusCurve also leads on update cadence (every 2 weeks vs every 4 months).

FocusCurve holds the better App Store score, 4.0 against 2.9. Both are backed by a comparable volume of ratings — 17 and 6 respectively.
