Email SupportFrequently Asked Questions
How do I switch between decimal and h:mm format?
On the Time tab, tap the decimal toggle. Zulu+ remembers your last choice the next time you open the app.
Which unit categories are supported in Convert?
Length, volume, temperature, weight, speed, and pressure — each with multiple units to choose from, not just a fixed pair.
How is the jet lag estimate calculated?
Zulu+ uses your departure and arrival time zones to work out real flight duration, how many time zones you cross, and the direction of travel, then estimates a typical recovery window based on that.
Does Zulu+ require an account or subscription?
No. Zulu+ is a one-time purchase — no account, no sign-in, no subscription, and nothing is tracked.
