The idea that you can send someone a letter or a symbol, one at a time to say something is laughable. For example you would need to send 5 texts to say hello! **Developer response:** The redline sticker pack includes all letters in lower and uppercase. That you can only use one sticker at a time is true, however that’s a limitation of sticker packs. Nonetheless you’re able to use several stickers — one after the other — to write words. Also it includes sticker for common errors like “your” vs “you’re”, so that you can correct this error fast and easily. ### 5/5 — So much fun! *2017-04-07* Love this app! Took a second to figure out how to use it (maybe add a few instructions) but love getting to use it on big group texts. ## Frequently asked questions about Redline ### What is Redline used for?
