Cube Timer vs Fuel Planner

Cube Timer, the sleek and intuitive timer designed for speedcubers everyday use. With a distraction-free interface and precise timing, it’s the perfect tool to track your solves and improve your speed.

Fuel Planner puts professional flight departments’ tankering maths in every pilot’s pocket. Just enter your route, fuel prices, reserve policy and (optionally) weight-penalty %, then tap Calculate. Behind the scenes a dynamic-programming engine compares unrestricted and ramp-fee-waiver–constrained strategies, optimising gallon purchases at every stop. You instantly receive: a one-paragraph “Pilot Action Brief” telling you exactly how much to uplift at each leg, and a detailed cost breakdown (fuel, ramp fees, weight-penalty) for audit or dispatcher review. Trips can be saved, shared as a single file, or re-imported later. Everything stays on-device; no network connection, log-in, or subscription required. Built natively in SwiftUI, Fuel Planner works offline, respects your privacy, and calculates results in a blink even for multi-leg itineraries.
