Once your tweets are archived you can express yourself by privately annotating them as well. Adding as much extra text & images as you want, and all of this is kept private and offline in your twitter diary.
Custom timeline filters allow you to sort and organize your timeline in amazing ways. You can group your timeline tweets by screen names, filter out tweets that contain images and links, or even reverse your entire timeline, so your tweets load from the bottom down, allowing you to read conversations naturally as they evolve.
tweetary makes full use of icloud,which means your diary and smart collections are synced across ALL your apple devices.
