Verdict

The call

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.
