Celo app for iPhone and iPad

In Latin, Celo means secretive. So does the purpose of Celo app, too - keeping secret.

When starts it is nothing more than a simple tip calculator. Upon specific touch combination it reveals it’s secret login area which takes the user to his/her own secret ground. User can stores their private files, i.e. images, videos, documents, for later viewing out of prying eyes.

As an extra secure safekeeping, the app comes with a Guest login feature. User can route any unintended friend with Guest login/password to an area where no private files will be shown.

The app also comes with OneDrive cloud storage integration. User can download or upload files between Celo and the cloud storage system. This requires user to be registered with the cloud service, though.
