I recently purchased an iPhone 4s for myself and started using it. After using it for a week and downloading many apps, I realized that I need one app that will help me plan out my travel dates, my daily budget, daily schedule and remembrance notes. I used the default feature provided on iPhone 4s but they weren’t providing features that were needed. It was just a simple version with no in depth features. My girlfriend told me that Microsoft’s OneNote mobile 1.3 is the best application for this purpose. Can someone tell me from where should I download this app for my iPhone 4s?
