I'm a disorganized person who uses an iPhone and various cloud services to store a variety of files. For someone like me, free app Octonius restores some order to my life. With it, I can search Dropbox, Evernote, and Google Drive from a single spot and share files or groups of files.
To get started, you must provide Octonius an e-mail address to create an account. Then, you can connect the app to your Dropbox, Evernote, and Google Drive accounts. Note: you can connect only one account per service.
Once you have linked your cloud accounts to Octonius, you'll be taken to the app's home screen, which features four options -- Flow, Collections, Browse, Cloud Search -- above a blank area that will eventually keep you abreast of recent file changes, tasks due, and reminders you have set.
The Flow page shows you a chronological list across all three services of the files you recently changed. The Browse page lets you drill down to each of your services, browsing your list of folders and files therein.
For each file, you can swipe left to reveal four buttons. From left to right, they let you add a note to the file, add the file to a collection, set a reminder, and share the file. Notes appear in small, gray text below a file's name. Collections we'll get to in a moment. Reminders are self-explanatory, while your sharing options are via email or Evernote.
You can create different collections that comprise files from any of the three linked cloud services. From the list of your collections, you can swipe left to share a collection of files via e-mail or Evernote. E-mail recipients of a collection will receive links to download each file from its original source.
Lastly, the search function lets you search across all three cloud services by keyboard. To the left of each search result is a small, gray icon that shows you on which service it resides. It shows you if a file is part of a collection or has a reminder or task assigned to it.
Free and ad-free, Octonius is worth investigating if you have trouble maintaining order in the cloud.
