Delkoku - Leave-By Alarm

About this app

"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.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
