Please use my app MapCam, if you additionally want to add precise geographical positions to your photos.
TextCam offers you the following functions:
✔ Use existing camera apps. Many apps are compatible, e.g. the most preinstalled ones, Camera MX, Cymera, LINE camera, pudding camera, Camera FV-5 Lite, Camera360 Ultimate etc.
✔ Add a descriptive text (a photo caption / label / tag) to your photos right after taking them. The text can be read by many websites/tools (e.g. Facebook, Flickr, Picasa, GeoSetter, XnView, digiKam etc.), and by my apps EagleEye and PhotoMap on your smartphone/tablet.
✔ Share your photos just after taking them, e.g. via e-Mail, Facebook, Flickr, Google+, Instagram, MMS, Picasa, Skype, Twitter, WhatsApp, Dropbox etc.
