I am currently using RNoets: Nurse's Clinical Pocket Guide. it has lots of different helpful info for you to use during your clinical. Its handy pocket size and waterproof pages are great for students on the go, while NCLEX tips, highlighted throughout, make it perfect for those preparing for the licensure exam. i was trying to use my iphone to create flashcards but my school does not allow us to use smartphone during the clinical so it was kind of pointless for me X_X but i really think that iphone is a really helpful tool for you to put in all the helpful info with you. I hope this is helpful :)
