What everyone else said. I have the forward movement website on a tab on my phone, and try to do the Morning Prayer most week days.
A portable non electronic resource is a pretty little book called Hour by Hour. It contains a week's worth of short excerpts from the daily prayer services and short scripture passages.
If your main goal is a portable way to pray the offices, one “off the beaten path” option is <em>Hour By Hour</em> which is a slimmed down version (it doesn’t follow the lectionary, it’s more like a weekly pattern similar to noonday prayer/compline). It’s not the actual Daily Office but I still find it a fulfilling prayer practice from time to time, and it is the same size as St. Augustine’s which makes it pretty good for on-the-go prayer.
Do you have Hour By Hour? It’s like an abbreviated Daily Office prayer book. Maybe that fits what you’re looking for?
