this may be redundant already, but I use the you version bible app. It helps to start a yearly through the bible plan at the beginning of the year, as the dates are right. However last year I started 18 days late, and so during the year, you just have to read those 18 days , so you make sure you are 18 days ahead of schedule then you will be fine. I read nicky gumbel through the bible, he is a great devotional writer. If I don't have time, I just skip the devotion.

but it takes fifteen to twenty minutes a day. If you miss a few days, you just read a half hour on weekends. make sure you don't get too far behind. But it's a good system it reads one psalm, one proverb, one old testament, and one newtestament. Also you can find others you know on there, by inviting them through messenger or email to do a plan with you. One guy at work, I send devotionals to all the time. We did a christmas one and a christian investors one.
