InkMemo

InkMemo allows you to easily record and organize your thoughts.
You can add memo to a specific day. You can also view and create memo directly in the calendar view. (You can also view events from your system calendar in this app)
You can attach a picture, sketch some art, draft some words, or save a map location coordinate to a memo. If you are using iPad, you can use your Apple Pencil to easily create a memo by hand writing.
Your memo is securely synced across your Apple devices using your Apple ID and iCloud storage.
