# Green Drive vs Cal Plus

The clearest difference is in-app purchases: Green Drive at none against Cal Plus's 4. Green Drive also leads on iOS requirement (12.0 vs 16.0). Cal Plus's advantage is update cadence (every 4 days vs every 6 weeks) and review sentiment (63% vs 35%). On price, rating, ads and device support there is nothing between them.

Both are free to download. Cal Plus sells 4 in-app purchases, starting at $19.99 per year. Green Drive asks for nothing beyond the download.

Green Drive holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cal Plus has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 35% of Green Drive's written reviews are positive against 63% of Cal Plus's, so the app with the better star average is not the one people write more warmly about.

Green Drive ships an update every 6 weeks, Cal Plus every 4 days. The most recent releases landed on November 2, 2026 and November 8, 2026 respectively.
