## Description

Work backward from your desired arrival time, set a departure alarm, and keep travel preparation on schedule.

"Just five more minutes" is the killer. Suddenly, your leave-by time is already gone.

Delkoku is an anti-lateness alarm: enter when you want to arrive, and it automatically counts back to
- when you should leave home, and
- when you should start getting ready.

■ Staged alarms stop time-blindness
Start prep → 10 minutes out → 5 minutes → leave now!
The classic multi-stage alarm technique loved by people with ADHD and anyone with a slippery sense of time, set with one tap. Alarms ring even while the app is open.

■ Delkoku does the math, you just get ready
Enter arrival time, travel time, prep time, and a safety buffer - the back-calculation is automatic. Save your frequent places and travel time from your current location is computed in one tap (train, car, walking).

■ Departure countdown
A big ring on the home screen counts down to departure every second. Tap "I left!" to stamp the moment.

■ A track record builds the habit
On-time departure rate, consecutive on-time streak, and a 14-day chart. Not to scold you - to stack up the days you made it.

■ Privacy first
Events, places, and records stay on your device. Nothing is sent to a server. Location is used only to compute travel time.

■ Everything is free
Unlimited places and events. Back-calculation, staged alarms, and stats are all free. The bottom banner ad can be hidden forever with a one-time "Remove Ads" purchase ($0.99, no auto-renewal). No subscriptions.

For the days you absolutely cannot be late - go with Delkoku.

Note: This app is not a medical device. It is not intended to diagnose, treat, or prevent ADHD or any condition, and is no substitute for medical advice.
