Jumptuit's free Android app lets you access, sync, copy, and share files stored on all your devices and cloud services with a single log-in. It can create slideshows and playlists and even swipe between files in different locations. Like the app, Jumptuit's basic service is free across all platforms.
Multiple sign-in options: We could create a new account or sign in to Jumptuit using Facebook, Twitter, Google+, Dropbox, and other services.
One for all: Jumptuit let us add and sync images, songs, documents, and other files from our phone's storage, Google Drive, and other sources, and sync or share it with an equally wide range of destinations with a few taps.
Expiration date: It's easy to set an expiration date for shared files.
Sign-up issues: We encountered many problems when trying to create a Jumptuit account from our Android 4.2 phone or via Facebook and other social media. At times, servers were unavailable. The Security Question would not display our choices, yet we couldn't register without it. In the end we had to sign up to Jumptuit on our Windows PC and reinstall the Android app to access Jumptuit's services. Things went well enough after that, though.
Select all: A Select All option for adding files and folders would be nice.
The ability to sync and share files across all devices and services shouldn't be underestimated, so Jumptuit proved well worth the extra effort required early on in the setup process.
