The last time I wrecked my smartphone I used PocketMod to keep track of myself until I could get a replacement (sad that my world has come to this but that's how many of us live these days).
I also experimented with the Hipster PDA:
http://www.diyplanner.com/templates/official/hpdaIt's the same idea as PocketMod only instead of sectioning a sheet of paper you print onto index cards. The template download has a huge number of templates and in many paper sizes so you can pick what size of index card best suits your needs....or pocket.
Personally I like PocketMod a bit better because I can print one a day and keep things tiny. I found with HPDA I'd have more cards every day...just in case. Plus you can print a PocketMod almost anywhere...not the case with index cards.
