It depends on the specific app. Usually, there's a 'History' or 'Watched' section somewhere in the menu.
You can try popular reading apps like Kindle or Wattpad. They usually have a wide range of stories for you to choose from.
You can try looking on app stores like Google Play or the App Store. Just search for keywords like 'story reading app' and you'll get a list of options.
You can try Webtoon. It's a popular app that offers a wide range of manhwa.
You can usually find the manga by searching for the specific title or genre in the app's manga section.
You might try searching on popular story-sharing platforms or specific Hooked App forums. Some users might have shared such content there.
Movie and TV Daquan was an online video sharing platform that allowed users to share and search for movies, TV series, TV programs, and other video content. You can search for movies or TV series that you are interested in on the film and television encyclopedia website or browse the video categories on the website to find content that you are interested in. At the same time, the movie also provided video playback, download, sharing and other functions to facilitate users to better watch and save video content.
You can start by looking at the user ratings and reviews. The stories with the highest ratings for scariness are likely to be really good. Also, check for tags like 'horror' or 'nightmare - inducing'.
I'd suggest looking into apps like MangaToon or Manta. They sometimes offer free access to manhwa. Just make sure to check their terms and conditions for any restrictions.
I'd recommend Tachiyomi. It's a popular choice among manga readers. However, make sure to download it from a trusted source as there might be unofficial or modified versions that could pose security risks.
You could try Manga Storm. It's a popular option for iOS and has a decent collection of manga.
