TachiyomiSY Guide 2026: Download, Features & Setup

The basics

What Is TachiyomiSY?

TachiyomiSY is a manga reader that lets you read manga, manhwa and webtoons from online sources or from files saved on your phone. It started as a fork of TachiyomiAZ, and today it pulls its core code from Mihon while also borrowing ideas from other forks such as TachiyomiJ2K and Neko. Because of that history, calling it “just a fork of Mihon” is not quite right, since it came from a different branch and later lined up with Mihon as its base. The project is released under the Apache-2.0 license, so anyone can read the code on GitHub. The app does not ship with any manga, which means you add sources yourself through extensions, the same way you would in Mihon. Many readers still search for it as Tachiyomi SY, or call it SY for short.

How It Differs From the Original Tachiyomi

The original Tachiyomi stopped on January 13, 2024, and its last version was v0.15.3. Since that day it has received no fixes, so it cannot keep up with new Android versions or with changes on manga websites. Old Tachiyomi apps now show only “Outdated App” entries when you add the Keiyoushi extension store, which makes them almost useless for reading. SY took a different road, because it kept getting releases and moved its base to Mihon, the community project that carried the Tachiyomi code forward. On top of that base, SY adds extra library tools, extra reader options and deeper support for some sources.

Who Builds TachiyomiSY?

The app is created and maintained by jobobby04, who has worked on it since the GitHub repo opened on March 30, 2020. Two other names appear in the official credits: she11sh0cked built the extra tracking, filters and recommendations, and az4521 wrote the base recommendations and TachiyomiAZ itself. Volunteers translate the app on Weblate, and Mihon lists this SY fork as endorsed, next to TachiyomiJ2K, TachiyomiAZ, Yōkai and Komikku.

Official download

TachiyomiSY Download: Official APK Files

The only official place for a TachiyomiSY download is the releases page of the SY repo that jobobby04 runs on GitHub. Plenty of websites offer copies or “mod” versions, but those files can be changed by anyone, so they are not worth the risk. SourceForge does keep a mirror of the same files, although it is not linked to the project, and its page still says the app needs Android 6.0, which is no longer true. Since 1.12.0 the release notes skip SHA-256 checksums, so getting the file from GitHub is the safest choice.

Which TachiyomiSY APK Should You Choose?

Each release on GitHub comes with five APK files, and the right TachiyomiSY APK depends on the chip inside your device.

The official release notes say to pick the universal file if you are unsure. The file names on GitHub end in “.apk.apk”, which is a small naming slip and does not mean the file is broken.

Stable vs Preview Builds

Stable builds are tested releases, while each TachiyomiSY preview is made from the newest code and lives in a separate repo called TachiyomiSYPreview. The latest preview is build 615 from October 28, 2026, and its number matches the commit count of the project. Preview builds are already based on Mihon 0.21.2, so they get newer extension store support, clearer install errors for extensions and a fix for Mihon backup compatibility. They also carry fresh SY tools, such as manual merging inside the library, feed backups and gesture controls for autoscroll. The trade-off is that previews can have new bugs, and one maintainer told a user to update the preview by hand, so check for new builds yourself.

Still on Android 6 or 7? Use Version 1.13.1

TachiyomiSY 1.13.2 dropped support for Android 6 and 7, so phones running those versions need 1.13.1 instead. It is the last build for them, and its update checker is turned off, which means it will not tell you about newer releases. Keep that APK saved in case you reinstall later.

First setup

TachiyomiSY Setup: Add the Extension Store

A fresh install has an empty Browse tab, so the first part of TachiyomiSY setup is adding an extension store. Keiyoushi is the most used store, and it officially supports SY from version 1.13.2 onward. Since Mihon v0.20.0, the app calls these lists an “extension store” instead of a “repo”, so look for that name in the menu.

1. If you used extensions before, uninstall all of them first, because old extensions from another source will not get updates.
2. Copy the store link from the official Keiyoushi website.
3. In SY, go to More, then Settings, then Browse, and open Extension store.
4. Tap Add, paste the link and confirm it.
5. Close the app fully and open it again so the extension list reloads.

Keiyoushi also has a one-tap “Add store” button on its website, but that button needs Mihon 0.21.3 or newer, and SY stable is based on 0.20.1. That is why the manual steps above are the reliable way to add the Keiyoushi extension store in SY. Our Mihon extension repo list covers other stores and their links.

Install Your First Extensions

After the restart, open Browse and switch to the Extensions tab, where you will see every source from the store. Tap Install next to the sources you use, and they will show up under Sources a moment later. If you moved from another app, the Migrate tab in Browse lists the extensions your library still needs. When a series is hard to find, search for its Japanese title in English letters, such as “Boku no Hero Academia” rather than “My Hero Academia”. Our guide on how to install extensions shows every step.

Turn On Optional Hentai Features (18+)

SY includes adult-focused tools, including a built-in E-Hentai and ExHentai source, but they stay off until you enable them. The switch sits in the advanced settings, so you only see these features if you choose to turn them on yourself. If you never touch that switch, SY works as a normal manga reader for readers of all ages.

Daily use

How to Use TachiyomiSY

Once your sources are set up, daily use follows the same flow as Mihon, with a few extra shortcuts on top. The sections below walk through each part of the app in the order most new users need them.

Navigating the Interface

The bottom bar holds five main areas: Library, Updates, History, Browse and More. Library shows the titles you saved, Updates lists new chapters, and History shows what you read last. Browse is where your sources, extensions and the migration tool live, while More holds settings, backups and downloads. SY adds a Feed tab inside Browse for its Latest tab feature, so new releases from your chosen sources are always one tap away.

Finding Manga

Open Browse, pick a source and use the search bar to look for a title, or scroll through its popular and latest lists. If you are not sure which source has a series, use global search, which checks all your installed sources at once. Sources carry different titles and sometimes different chapter counts, so trying a second source is often the quickest fix when a series is missing.

Adding Manga to Your Library

On any manga page, tap Add to library, and SY will ask which category the title should go into. Categories such as Reading, Plan to read and Completed keep a growing library easy to scan from day one. Saved titles also get checked for new chapters during each library update.

Reading Chapters

Tap any chapter to open the reader, and swipe or tap the sides of the screen to turn pages. Standard manga works best in paged mode, while manhwa and webtoons work best in vertical mode, and SY usually picks the right one by itself. You can still change the mode for one series without affecting the rest of your library.

Managing Downloads

You can download single chapters, a range of chapters or every unread chapter for offline reading from the manga page. Downloading over Wi-Fi saves your mobile data, and the option to delete chapters after reading keeps your storage free. Check the download folder in the settings as well, because a large library can fill your phone faster than you expect. The download queue in the More tab shows what is still waiting.

Using Categories

Categories split your library into groups, and you can choose which of them refresh during updates to keep them short. Dynamic categories go one step further, because SY can sort titles into views by source, status or tracking without any manual work from you. Both kinds work together, so your own groups stay while dynamic views add a second way to browse.

Tracking Your Progress

Open a manga page and tap the tracking button, then sign in to a service such as AniList or MyAnimeList and pick the matching title. After that one-time setup, every chapter you finish updates your list on that service right away, even when you read offline and sync later.

Updating the Library

SY can check for new chapters on a schedule, or you can pull down on the Library screen to refresh it right away. A huge library refreshed too often can hit HTTP 429 errors, which means a source got too many requests from you, so a few scheduled updates a day are enough for most readers with large libraries.

Reader Settings

Open the reader menu while reading to change the reading mode, screen orientation, page transitions, zoom and background color. Autoscroll speed is set here as well, so you can test it on a long chapter until it feels right. Each change can apply to one series or to every series, depending on the option you pick. Spending a few minutes on these settings once will improve every chapter you read after that.

Moving Your Library From Mihon or Tachiyomi

You can move your whole library to SY with a backup file, and you keep your read history in the process. In Mihon, open Settings, go to Data and storage and create a backup, which saves a .tachibk file on your phone. Then open SY, go to the same screen, choose Restore and pick that file. After the restore, add the Keiyoushi store and use the Migrate tab to reinstall missing sources. On 1.13.2, some users see a database error during the restore, and the fix is to close SY fully and try again. Back up very large libraries without chapters to avoid memory crashes. Our Tachiyomi backup guide explains each option.

Compare

TachiyomiSY vs Mihon

TachiyomiSY vs Mihon is the question most readers ask before they install, and the answer depends on how much control you want.

The table shows that the two apps share the same core, so reading, extensions and trackers feel almost the same in both. The real gap is in the extra tools, since SY adds a lot of menus that Mihon leaves out on purpose to stay simple.

Which One Should You Pick?

Pick SY if you follow many series across several sources, because merged manga, the Latest tab and the library search engine save real time every day. Pick Mihon if you like a cleaner app that gets core fixes first and you rarely need more than the basic reader. Since both apps can sit on one phone, you can install both, restore the same backup in each and test them side by side for a week before you decide.

Computers

Does TachiyomiSY Work on PC?

SY is an Android app, so it does not have a Windows, Mac or Linux version. The only way to use it on a computer is through an Android emulator, and that is where the x86_64 APK comes in handy, because it matches the chip that most emulators use. Expect some trade-offs, since performance depends on your computer and reading with a mouse feels different from swiping on a phone. Our guide on how to install Tachiyomi on PC explains the emulator setup step by step.

Fixes

Common TachiyomiSY Problems and Fixes

These are the real problems SY users reported on GitHub in 2026, along with the fixes that worked for them.

If none of these work, the SY team asks users to look for help in the Mihon Discord, where many of these problems have been solved before. You can also check our Tachiyomi troubleshooting guide and the list of fixes for when you can’t install Tachiyomi.
