What's new
RELEASE · V1.1.115 · 2026-09-28 · Beta
AIC Layout gets a Power tab and a guided tour, Artificing is redesigned, notices reach you as Windows notifications, the map follows you ten times a second, four new farming zones, Purrchena's full kit and eight new team comps.
AIC Layout › Power
A new inspector tab that designs a pulsed thermal pool: tell it how much load your base has to cover and it proposes how to feed the Thermal Banks through splitter chains, charts one full cycle and places each branch on your layout. "Load an example layout" fills a sheet with a working battery line to explore.
AIC Layout
A guided tour on your first visit; the core can be moved or removed; item and formula search in the inspector; 70×70 sheets. The Protocol Stash gets its three modes (linked, local and off) and, as in the game, never takes items out of the depot. Thermal Banks can be switched off and burn one battery type at a time, Depot Bus parts must be chained to a Depot Bus Port, Item Control Port limits work per minute, and new warnings point out machines slowed down by their inputs.
Artificing, redesigned
Pick the piece you own, choose the substat and how far to raise it, and see which pieces to craft as fodder, cheapest first, and what it will cost. Everything fits the smallest window with the ad panel open.
Notices as Windows notifications
While EndSync is minimized and the game is closed, notices arrive as Windows notifications; click one to open the related section. You can turn it off in Settings › Notices, where "Test" shows one.
Map
Your position updates about ten times per second. With Follow on you stay centered; with Follow off the map stays put and only moves when you walk out of view. A counter shows the tiles still loading.
Banner
The tab is named after the current featured banner, and tabs inside switch between the featured operator and the rerun. Home and the overlay show "Ongoing" for banners without an announced end instead of a countdown.
Farming: four new zones
Sword Vault Dale, Yinglung Pass, North Wuling Exclusion Zone and Snowy Forest join the essence planner: 12 zones in total.
Model in progress
Damage and Compare show a note for operators whose kit is still being modeled (Typhoeus): their numbers are provisional. Rotation leaves out Typhoeus and Purrchena until their kits are modeled.
Purrchena
Her complete kit (skills, talents and potentials), profile, her weapon Dessert Moment, recommended gear and 10 kit keywords in the glossary.
See them on the webEight new team comps
Including a new Perlica guide and Purrchena teams for Rossi, Typhoeus and Yvonne: 71 comps across 11 guides.

One player made this
Tired of spreadsheets? Same.
EndSync started as a personal tool — one player tired of juggling spreadsheets and a dozen browser tabs just to plan an Arknights: Endfield account.
It grew into a full companion: a roster tracker, a custom team builder with curated comps, a curated tier list, a real damage engine, an AIC layout planner, a wiki, an interactive map that knows where you are standing, a profile that keeps your journey, and a lightweight in-game overlay — all in one window, and one panel that follows you into the game.
It's a hobby project, built and updated by a single person as the game grows, and powered by the Endfield community and its creators. The goal is simple: spend less time in spreadsheets and more time actually playing.

Good to know
What is EndSync?
A companion app for Arknights: Endfield. It tracks your roster, builds teams on top of curated guides, calculates damage, maps every gatherable with a live "you are here" marker, keeps a profile of your account, and shows a lightweight overlay in-game — so you can plan your account without spreadsheets or a dozen tabs.
Is it free?
Yes. EndSync is a free hobby project made by a single Endfield player, distributed on the Overwolf store.
Do I need Overwolf?
Yes — EndSync runs as a native Overwolf app, which is what powers the desktop window, the in-game overlay and the game events behind roster sync and the map's live position. Installing it from the Overwolf store sets everything up.
Does my data leave my PC?
No. Everything runs on your PC and needs no account: your roster, teams and profiles stay on your machine, and you can export them as a file whenever you want. The app goes online for the data pack — guides, gift codes, translations — and for the map tiles, which come from SKPORT / Gryphline; your account data is never uploaded anywhere.
Does it work with more than one account?
Yes. EndSync keeps one data profile per account. When the game reports a different account, the app switches on its own and keeps the previous one intact — roster, teams, checklist and journey included — and you can switch back from the Profile tab.
How does the map know where I am?
With the game open, Overwolf's game events report your position and EndSync draws a "you are here" marker that follows you, changes level with you and points to the nearest marker you haven't collected. Your position is only shown, never stored; the map works without the game too, you just navigate it by hand.
How does the in-game overlay work?
Press the hotkey (Ctrl + F8 by default) to bring up a compact panel over the game with the tier list, base codes, team comps, their rotations and an agenda — including which weapon essences drop in the zone you're standing in. Press it again to hide it. You can also show it as a separate desktop window, for a second monitor or the game in windowed mode, and set its opacity in Settings.
Is this an official Gryphline / HyperGryph product?
No. EndSync is an unofficial, fan-made tool with no affiliation to HyperGryph or Gryphline. All game names and assets belong to their respective owners.
Which languages does it come in?
English and Spanish, written by hand, plus Chinese (Simplified), Japanese and Korean since 1.1.49. The app picks your system language, lets you choose it on first launch and switch it in Settings. Names, skills, talents, weapons, gear, profiles and medals use the game's official texts, and the app's own pages follow the game's terminology; team guides stay in English and Spanish. Corrections arrive through the data pack, with no update needed.
