# Flexitime vs ShiftZen

The clearest difference is ads: Flexitime at none against ShiftZen's shown. Flexitime also leads on update cadence (monthly vs every 12 months) and review sentiment (68% vs 59%). ShiftZen's advantage is rating (3.9 vs 3.5) and ratings volume (18 vs 6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Flexitime sells 3 one-off in-app purchases and ShiftZen sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ShiftZen holds the better App Store score, 3.9 against 3.5. Both are backed by a comparable volume of ratings — 6 and 18 respectively. Written reviews complicate that: 68% of Flexitime's written reviews are positive against 59% of ShiftZen's, so the app with the better star average is not the one people write more warmly about.

Flexitime ships an update monthly, ShiftZen every 12 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
