Verdict
The clearest difference is review sentiment: Gearlog Tracker at 100% against Fuel's 50%. Gearlog Tracker also leads on rating (5.0 vs 3.1) and update cadence (monthly vs every 10 months). Fuel's advantage is in-app purchases (none vs 2) and ratings volume (33 vs 4). On price, ads and device support there is nothing between them.
