# Micro Fi vs Star Map Tracker

The clearest difference is review sentiment: Micro Fi at 75% against Star Map Tracker's 29%. Micro Fi also leads on in-app purchases (none vs 3) and ratings volume (4 vs 1). Star Map Tracker's advantage is rating (5.0 vs 4.3) and update cadence (every 5 months vs every 44 months). On price, ads and device support there is nothing between them.

Both are free to download. Star Map Tracker sells 3 one-off in-app purchases. Micro Fi asks for nothing beyond the download.

Star Map Tracker holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 75% of Micro Fi's written reviews are positive against 29% of Star Map Tracker's, so the app with the better star average is not the one people write more warmly about.

Micro Fi ships an update every 44 months, Star Map Tracker every 5 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
