Stiko is a mobile application available for iPhone and Android devices that converts screenshots and videos into stickers for WhatsApp. Its primary function is to streamline the process of transferring stickers from social media platforms, particularly TikTok, to the WhatsApp messaging app. The application is designed to process media directly on the user's device, with screenshots and videos from the gallery being analyzed locally. The app's main workflow involves two distinct methods for sticker creation. For still images, a user captures a screenshot of their TikTok sticker tray and imports it into Stiko; the application then automatically detects and crops each sticker from the image, allowing the user to remove unwanted items or add missing ones before exporting the final pack. For animated stickers, the user can import a short video or screen recording, select a specific fragment, and Stiko will prepare the loop for the motion effect. Once a pack is assembled, the user can tap "Add to WhatsApp" to confirm and export it directly into their chats. Additional features include a community section where users can discover and add popular sticker packs created by others, and a personal library that stores a user's packs and drafts on the mobile device for later review or export. The app does not require registration for creating or exporting packs; an account is only necessary for users who wish to publish their own packs to the community. Stiko is free to download and use, with an optional one-time purchase available to remove advertisements.
