Verdict
The clearest difference is review sentiment: Time at 100% against fuelTool's 50%. Time also leads on update cadence (monthly vs every 3 months). fuelTool's advantage is rating (5.0 vs 3.0) and ads (none vs shown). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
fuelTool holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 50% of fuelTool's written reviews are positive against 100% of Time's, so the app with the better star average is not the one people write more warmly about.
fuelTool ships an update every 3 months, Time monthly. Both last shipped on November 1, 2026.
