I will explain what I have done, and it might work for you, perhaps not. I have a hard copy of the United States Government Appointment Book 2016 that I use to write in to record the time I complete all my activities for the day, or record future activities. I do this so I can refer back to the days/times I completed actions. It is broken down into 15 minute segments...very similar to a Franklin planner Day Runner, etc. Since Apple Pencil is so doggone close to using a real writing instrument, I simply wanted to use my iPad Pro to do this same activity so I don't have to carry two items with me. Here is what I have done...
1. Installed the GoodNotes 4 app
2. Installed the Scanner Pro app make by Readle
3. I "scan" my hard copy Appointment book using Scanner Pro
4. I "Share As" PDF, tap "Open In", and then "Copy to GoodNotes"
5. The initial above sequence creates a New Notebook for you, which I labeled Appointment Book
6. Thereafter, using steps 1-4 above, if you have GoodNotes 4 open when you scan the page, it allows you to insert the page "Above" (prior page) or "Below" (next page), which makes it very convenient.
Why am I using GoodNotes 4? It allows for the searching for handwritten notes that I find extremely useful as compared to leafing through my weekly pages in the hard copy text. As far as writing, I also have found GoodNotes 4 to be extremely useful in rejecting palm resting, etc. An easy program to use indeed.
This obviously is not a straight-up app to solve the problem, but you know it really works for me. Using the steps above because I am used to doing it now takes me all of 5 seconds to get a new week's worth of appointments into soft copy that I can write, etc.
Note: you can use Scanner Pro app to "scan" anything into PDF form and then import into GoodNotes 4, such as Monthly calendar, etc. Just use your imagination.
