Verdict
The clearest difference is rating: X at 4.7 against Fuelman Maintenance's 3.0. X also leads on ratings volume (9 vs 2) and iOS requirement (8.0 vs 15.1). Fuelman Maintenance's advantage is monetization model (free vs paid) and update cadence (every 2 months vs every 13 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
X holds the better App Store score, 4.7 against 3.0. Both are backed by a comparable volume of ratings — 9 and 2 respectively.
