Traveler's Check
Checklist for travelers
Even the best of us forget things. I personally have arrived at the airport without a passport, left the apartment without keys in the middle of winter, and gone on many a weekly commute without my phone charger.
Traveler's Check reduces the chances of such things. Writing a checklist is a hassle - a single touch of the thumb is not so bad.
Common items are there for you, additions are saved.
