instaTags is an Instagram-style app for Nokia S40 phones where you can add filters and hashtags to your photos.
You can take photos through instaTags by touching the screen and apply one of 7 themes (just 3 in the free version). You can choose from 14 default hash tags to add, which contain a mix of English and Indonesian words (you can't enter your own). There's an option to save the photo, but not to share it.
instaTags is an easy way to add effects - but then so is the default S40 image editor.
