Add Text is an iPhone application developed by Appostrophe AB that allows users to add beautiful text layers and captions to their photos. With this application, users can turn their photos into artworks with hundreds of unique fonts and colors. The app is free to use and offers unlimited text layers with customizable letter spacing and line height.

The app also provides the option to give text layers a 3D feel by changing their perspective and rotating text in all dimensions. Users can add shadows and change the opacity of text layers. The app offers a hand-selected color palette to choose from to bring life to your photos.

While the app itself is free to use, some additional design elements such as premium fonts and graphics require a paid subscription. The subscription is automatically renewed every month or year until canceled. Users can manage their subscriptions and turn off auto-renewal from their Apple ID account settings after purchase. Cancelling a subscription will disable auto-renewal, but the current subscription will not be refunded.
