# SPARKvue 4 vs micro

The clearest difference is rating: micro at 3.3 against SPARKvue 4's 1.9. SPARKvue 4's advantage is update cadence (every 2 months vs every 7 months) and ratings volume (638 vs 90). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

micro holds the better App Store score, 3.3 against 1.9. That said, the two scores are not equally well evidenced: SPARKvue 4 has 638 ratings behind it against 90, so its average is the more settled of the two. Written reviews complicate that: 46% of SPARKvue 4's written reviews are positive against 43% of micro's, so the app with the better star average is not the one people write more warmly about.

SPARKvue 4 ships an update every 2 months, micro every 7 months. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
