ChatSecure (Gibberbot) is a secure chat client capable of firewall and filter circumvention, surveillance blocking and end-to-end encryption. It works with Google, Facebook, any Jabber or XMPP server, such as OpenFire or eJabberD. Unlike Blackberry BBM’s broken single key security, Gibberbot uses the Off-the-Record encryption standard to enable true verifiable end-to-end encrypted communications.

A mobile app for controlling visual media and metadata in a manner that allows the person capturing the media to secure, protect it, and share it with only the people you intend to.

InformaCam uses the built in sensors in modern smartphones as well wi-fi, bluetooth, and cell tower information to create a snapshot of the environment in which an image or video was captured. This validates the date, time and location of capture. Digital signatures and encryption ensure that your media hasn't been tampered with and can only be opened by the intended recipient.

Maps API (A replacement of the often used google maps api with an open source one using OpenStreetMap.)

Network Location (Geo-location using wlan and data from Apple or a database of gsm phone cellphone towers)

Not useable yet:
LoginService (used by some Tasks/Feed -Apps) [Development]
Services Framework [Development]
Maps API v2: This time with onboard map rendering, so we can use it offline even for navigation purposes and search

Description:

Google apps track users more than most other apps as they are system-apps and therefore have full rights on android.

There are several problems with avoiding Google apps:

You won't get regular updates for your apps. Google's apps are not bad in functionality, but are in privacy.

No access to Play Store (There are many alternative markets, but nothing is as good for free apps as Play Store) Meanwhile, F-Droid provides nearly everything you need.

Some apps do not install because of missing Google Maps API

Some apps Force Close at start-up because of missing Maps API or market license check issues

Some apps hard-coded links to several Google Apps and therefore Force Close or react unexpectedly on certain cases.
