About
Ready to move the moment you land, or wrecked for days? • Just enter the time difference and days before departure • Automatically calculates a manageable pace of up to 1 hour of sleep/wake shift per day • Honestly flags it when your days aren't enough to fully adjust (no false confidence) For frequent international travelers, business travelers, and anyone with plans right after arrival. This app is not a medical device. It is a calculation tool based on general sleep-adjustment knowledge and does not diagnose or treat any condition. A one-time ¥300 (or local equivalent) purchase. No in-app purchases.
