One of the better looking lease-tracking apps, but calculations for current estimated mileage are off (for me, it lowballed by 40 miles). Granted that’s better than overestimated mileage, but I’d prefer accuracy.
How do I figure it’s off? Here’s my calculations, based on my current lease of 36,000 miles over 36 months: My lease runs June 18, 2014 to June 18, 2017, which means there’s 1096 days in my lease. As of the day I’m writing this review - August 4, 2014 - 47 days have elapsed since lease start, and my car had 24 miles on it when the lease began. The equation is easy:
((Miles allowed over term of lease) / (Number of days between Lease Start and Lease End)) * (Days elapsed since lease start) + (Odometer reading at lease start) = Current Allowed Odometer reading
So, that would be:
(36000/1096)*47+24 = 1568 (rounded up to nearest whole mile)
Lease Miles says my current “Safe Reading” is 1528 miles, an under-estimate of 40 miles. Again, this is better than a figure that is too high… but math is math, and accuracy matters. If the low estimate is intentional, then the developer should make that known up front.
