What's the best iOS app for adding custom fonts and backgrounds to Instagram Stories?

StoryFont for Instagram Story is a specialized tool for enhancing Instagram content with professional-looking typography and decorative elements. The app offers an extensive library of fonts ranging from elegant scripts to bold display typefaces, alongside curated sticker packs and animated backgrounds. Users designing promotional posts or personal Stories can quickly apply coordinated text and visual themes without switching between multiple apps. Key features include real-time preview, adjustable text colors with gradients, and one-tap sharing to Instagram. However, some reviews indicate persistent lazy loading when browsing sticker and wallpaper collections, which can slow down the creative process. Additionally, users report occasional unexpected sign-outs requiring repeated authentication. Despite these technical hiccups, the app maintains high ratings for its vast selection and ease of use, making it suitable for casual users and small businesses seeking polished social media visuals.
