Time to Takeoff

Know what to do but can't get started? Time to Takeoff times two moments separately: when you decide to start, and when focus actually kicks in. The gap between them is your takeoff prep time, and the app shows how it shrinks as your flights add up. HOW IT WORKS • Hold your phone upright and write the one thing you want to start as your destination. You can also say it. • Turn your phone sideways and tap "Get ready". The plane leaves the gate and taxis to the runway. • Begin your task. When you feel focus kick in, tap "I'm focused" and take off. • Cruise for the time you chose. If focus breaks, land for a short break and take off again. • After landing, look back at the flight path and your takeoff prep time. FEATURES • Takeoff prep time and focused time recorded separately • Average prep time and recent trend • 15, 30, 45 or 60 minute flights • Reissue a past destination in one tap • The screen dims while cruising so it doesn't pull your eyes away • Lounge music, captain and cabin crew announcements, takeoff sound and cabin ambience • One sound button switches between speaker, earphones only, and off • English and Korean • No account, no ads. Your log stays on your device.

Verdict
The clearest difference is in-app purchases: Time to Takeoff at none against ChessLock's 6. Time to Takeoff also leads on update cadence (daily vs fortnightly). ChessLock's advantage is device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
