How it works

Arkham Horror RPG Ledger keeps your group's Arkham Horror RPG investigators in one place. Every change shows up for everyone at the table straight away, on phones, tablets and laptops.

Getting started

  1. Sign in with Google, or with an email and password.
  2. Pick a username. It's the name other players see. Your email is never shown to them.
  3. Start a campaign or join one. Click + New campaign to start your own, or open the invite link a friend sent you. Invites sent to your email arrive in your inbox and wait on your My campaigns page.
  4. Make your investigator. Open the campaign and use the New investigator tab to build one step by step, or add a blank sheet and fill it in yourself.

Trying it without an account

The welcome screen has a sample campaign with an invented party: open sheets, spend dice and try the GM tab. Nothing you do there is saved.

To start your own, choose Start a campaign, no account needed. You get one campaign of your own where you're the GM, so you can make investigators, run a fight and try the Journal.

Who can do what

Inviting players

Owners invite people from the campaign's Settings page, right after creating a campaign, or any time later:

A campaign can have up to 12 members.

Inside a campaign

Party

Everyone's investigators at a glance: dice pool, horror, insight and injuries. Tap one to open their sheet.

Each investigator shows up to two status tags, most serious first: Dead, Lost forever, Dire, Wounded (pool limit at 0), Injured (has an injury), Traumatized (has a trauma), Shaken (a high horror limit) and Damaged (pool limit below max, no injury). With none of these they're Healthy. Enemies on the GM tab use the same words, plus Out once they're taken down.

Investigator sheets

Tap a portrait, the campaign picture next to the campaign's name, or a handout to see it full size. Spend and refill dice, take damage and horror, record injuries and traumas, manage skills, knacks, weapons, gear and money, and spend XP. The Recent list shows what changed. Open printable sheet gives a print-ready copy (print on Letter paper with background graphics on); Back returns to the ledger. In the installed app on iPhone or iPad, Print opens the sheet in Safari (iOS 17 or later) and brings up the print screen, because the installed app can’t print.

Injuries: roll at the table, then pick the result. A fall of 10 ft or more rolls 1d3 on the table instead of 1d6, plus 1d3 for every 10 ft beyond the first. Fire, lack of air, poison and disease give one of the unique injuries instead (Burned, Choking or Sickened): they add 1 to later injury rolls like any other injury, and a third of the same one is fatal.

Multiclassing: once an investigator has spent 125 XP, the XP section offers Multiclass · 20 XP. It raises the dice pool maximum by 1 (on the sheet, the party view and the printable sheet) and adds either a second archetype, whose knacks and skill limits become available too, or, staying in the same archetype, room for 2 more tier 1 knacks and 1 more of tiers 2 to 4. The owner, or a GM allowed to edit every investigator, can undo it.

Same investigator, new campaign: open the + New investigator tab. If you play investigators in your other campaigns, it lists them at the top under Bring an investigator you already have and copies the one you pick, with their skills, knacks, XP, gear, money, injuries, traumas and portrait. They start a fresh session (pool refilled, insight full). The original stays in its old campaign, and changes to one don't affect the other.

Finishing a campaign: when the story is over, the owner or the GM taps Mark campaign complete at the bottom of the Journal. The campaign moves to Completed on your campaigns page with its finish date. Everything stays readable (sheets, journal, recaps and history) but nothing can be changed, and session reminders stop. The owner or GM can reopen it.

Kits & supplies holds gear with use circles, like ammo: first aid and field surgeon kits, tool kits, candles, torches, flashlights and lanterns. Mark a use when you roll a 1 while using one (tool kits: mark one to get their bonus). When every circle is marked, Replenish it for its supply cost, or buy a new one if it can't be refilled. The printable sheet shows the circles, with used ones filled in.

New investigator

Builds a character following the Core Rulebook's creation rules, with the gear budget and XP worked out as you go. If you stop halfway, it's kept on your device for that campaign for two weeks; Start over clears it.

Next session

The owner (in the campaign's Settings) or the GM (on the GM tab) sets the date and time of the next game, where it is, and optionally how long it should run. Start typing an address in Where to pick from suggestions. Then:

Journal

The Gallery at the bottom is for pictures from your games: art, the table, your minis. Anyone in the campaign can add pictures with a caption; tap one to see it full size and swipe through the rest. You can delete your own; the owner and GM can delete any. Clues and handouts the GM has revealed, enemies the GM is showing, the campaign tracker (in-game date, open threads, people met and places), and Past sessions: a recap of each finished session, with the GM's summary on top if they wrote one.

For the GM

Your account

Click your icon at the top right and choose Your account to upload a profile photo or, without one, pick a color for your initial, or change your reminders and notifications. The same menu has Install app, Send feedback and Sign out. Delete my account removes your username, profile and sign-in, deletes campaigns you own and takes you out of the others.

Reminders & notifications

Under Your account, choose whether to get a reminder the day before a session (by email, and as a notification where they're on), and turn on notifications for the device you're using. You can get one when the GM reveals a clue to you and, if you like, when it's the investigators' turn in a fight. On iPhone and iPad, notifications work in the installed app.

Arrange your campaigns

On My campaigns, press and hold a campaign card (or click and drag it on a computer) and drop it where you want it. Your order is saved to your account, so it's the same on every device.

Install it like an app

Choose Install app in the menu under your icon. On an iPhone or iPad, tap Safari’s Share button and then Add to Home Screen. The ledger then opens full-screen from its own icon. On iPhone you sign in once more inside the app.

Questions

Do I need the Core Rulebook?

Yes, to play (buy it from Asmodee). The site tracks your game; it doesn't replace the rules. Knack effects and other game text here are short summaries in our own words, not the book's text, and you can edit them on your sheet. See About this site.

I can't change something on a sheet.

Only an investigator's player can change it (plus the GM's session tools, the owner if they've turned on Let me edit every investigator, and the GM if the owner has turned on Let the GM edit every investigator). Check who it says plays the investigator at the top of the sheet.

A banner says the daily limit was reached.

That shouldn't normally happen. If it does, changes won't save until it resets around midnight Pacific time; nothing already saved is lost. Keep track on paper until then and let us know with Send feedback.

It says I'm offline.

Your connection dropped. Changes you make are kept and sync when you're back online, as long as you leave the page open.

I didn't get the invite email.

Check your spam or junk folder for a message from arkhamrpgledger@gmail.com, and mark it Not spam so later ones arrive normally. Either way, the invite is waiting on your My campaigns page once you sign in with the address it was sent to.

I'm not getting notifications.

Open Your account and check that notifications say On for this device, then tap Send a test. On iPhone and iPad they only work in the installed app (iOS 16.4 or later), so install it first and turn them on from inside it. If the site says notifications are blocked, allow them in your browser's site settings or the phone's Settings › Notifications. While the app is open on screen you won't get a pop-up; new clues just appear in the Journal.

Something's broken or I have an idea.

Click your icon at the top right and choose Send feedback, or use Contact at the bottom of any page to send a message (no account needed).
