Description by Sebastian Kruse (from Google Play)
ER Companion is the complete interactive guide for Elden Ring, the Shadow of the Erdtree DLC and Elden Ring Nightreign. Explore every map offline, track your progress with smart checklists, plan complete builds with exact attack ratings, and look up any weapon, armor piece, talisman or boss in seconds.

INTERACTIVE OFFLINE MAPS
The Lands Between with the underground world, the Realm of Shadow from the DLC and Limveld from Elden Ring Nightreign. All map data works without an internet connection.
- Sites of Grace, Stakes of Marika and map fragments
- Dungeons, evergaols, divine towers and minor Erdtrees
- Bosses, NPCs, merchants and quests
- Golden Seeds, Sacred Tears, Crystal Tears and Larval Tears
- Weapons, armor, talismans, sorceries, incantations, cookbooks and Stonesword Keys
- Filter by type, region, or completion state, and search the whole map instantly

CHECKLISTS AND PROGRESS TRACKING
Tick off bosses, flask upgrades, map fragments, dungeons, weapons, armor sets, talismans, sorceries, incantations and more. Check entries directly from the map popup and see your completion percentage on a dedicated statistics page.

COMPLETE GAME DATABASES
- Every weapon and shield with upgrade paths, scaling and status buildup, including all DLC gear
- Armor sets with defense values and poise
- Talismans, sorceries, incantations, spirit ashes and Ashes of War
- Items, crafting recipes and upgrade materials
- Boss data with locations

BUILD PLANNER AND DAMAGE CALCULATORS
Plan a full character build with every equipment slot, see the exact attack power, defenses and stats for your level, and share builds with a short code. The damage calculators even show your damage against a specific boss, and the summon range calculator and drop locations round out the toolbox.

SYNC AND BACKUP
You can export and import a backup file, or move progress to another device with a sync code.

MADE FOR PLAYERS
- Works fully offline, so it is ready even without a connection
- Light and dark theme with several accent styles
- Available in 20 languages
- Optional ad-free unlock

IN-APP PURCHASES

Comments on ER Companion for Android

★★★★★ Eric Douglas · May 21, 2024
Good app so far! Nice map for reference. Also enjoyed the similar companion app for Zelda: Breath of the Wild. Thanks!
★★★★☆ Michael Donato · Oct 10, 2026
Amazing app and definitely use it every play through. Just missing the new Tarnished Edition changes to smiting stones being different now for several in the DLC and missing the new Weapon, Armor and Torent skins.
★★★★★ Salem Brown · Jun 29, 2025
I got the app free from the dev on reddit years ago, and I'm finally getting around to reviewing it. The app is amazing for literally all the information you need, everything from weapons, armor,all dungeon locations etc. and even lets you check off items, so you know what gear you haven't collected yet, I highly recommend.
★★★★★ DJ A!nstein · Jun 7, 2025
Amazing and Helpful app for Elden Ring. Use it along with walkthroughs of the game.
★☆☆☆☆ Nicola “Nikko” Heller · Feb 22, 2024
Kind of useless, as it only provides the map for free. You can use the Elden Ring Wiki in browser for that matter. All the checklists are locked behind paywalls.
★☆☆☆☆ lanolin · Jun 6, 2025
Saw some decent reviews, so I downloaded and bought the 5 dollars worth of otherwise free-to-find-online info. Whatever, we all got bills to pay. As soon as I started to use the build planner (the only part I'm interested in) I realize something very wrong... there's seemingly NO dlc gear included in the planner. Huh??? How am I supposed to plan my Dark Cooper from Twin Peaks build if a huge chunk of gear just isn't included in the app? Cool idea, but just badly done. Not worth
★☆☆☆☆ Chase Allen · May 28, 2026
No DlC weapon for the build planner. Which is the reason I paid for the content. My intent was to use it to make a build for twin replans blades.
