PowerArchiver

PowerArchiver is software that specializes in compress, encrypt, exchange and backup data. The job it does: designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. They are a very small team, 1 to 10 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

PowerArchiver is based in Reston, Virginia. Their site is powerarchiver.com.

Before you commit, look at portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
