Gnasher's Satchel^™

Your character, in your pocket. A free, 5E-compatible sheet that rolls with one tap, tracks the fight for you, and links live to your DM's screen. No account. No subscription. Works in a basement with no signal.

Gnasher in his rucksack form: a friendly canvas adventuring pack with a keyhole clasp, the Satchel mascot

Gnasher carries your dice, your sheet, and your notes, and he rolls right alongside you.

Phone, tablet, or laptop

Bring whatever screen you bring to game night. It loads like a page and behaves like an app.

Open it once

Tap Open the Satchel on the phone, tablet, or laptop you bring to the table. No store, no install, no account.

Add it to your home screen

iPhone: tap Share, then Add to Home Screen. Android: open the menu and pick Install app. It gets its own icon.

Signal optional

After that first visit it opens offline, sheet and dice and all. Rather own the file outright? The download gives you the whole app as one file.

What's in the bag

Everything a player reaches for, and nothing they have to set up.

A sheet in three minutes

Pick a class and level; proficiency, saves, hit dice, and spell slots fill themselves in. Or forge one from scratch in the new Forge: species, class, background, feats, spells, and gear from the free SRD 5.2.1, with every number computed for you. Own other material, or wrote your own? Put it in Your Books and the Forge uses it: species, backgrounds, feats, spells, items, whole classes and subclasses, typed in, loaded from a file, or read straight out of a PDF you own, kept in your browser and never sent anywhere. Or paste your D&D Beyond link, or drop a Foundry VTT file, and keep the character you already have.

The bookkeeping face

One-tap damage and healing, temp HP, death saves, conditions, spell-slot pips, and rests that do the right thing. Your class resources sit on the Fight tab as coins: Rage, Second Wind, Action Surge, Channel Divinity, Focus Points, Bardic Inspiration, Sorcery Points, Wild Shape and the rest, grown from your level, spent with a tap, and handed back by the right rest. Cast a spell and pick the slot; concentrate on one and the sheet asks for the save when you take a hit. Every rule, action, feat, feature and item in the free SRD 5.2.1 is a search away, with the dice in the text ready to roll. Saving throws sit on the sheet with their numbers, prepared spells are counted against your level, a multiclass caster gets a save DC per class, and the sheet prints on paper when you want paper. Your familiar, your steed and your summoned beast keep their own hit points and attacks on the Fight tab; a Druid wears a Wild Shape form and the sheet becomes the beast until you drop it. Fly, swim, climb and burrow speeds sit beside your walk. When your XP earns a level, the sheet asks whether you want it now. No character yet? Sit down at the table by name and watch.

Tap to roll

Every check, save, skill, and attack rolls with one tap, advantage and disadvantage included, with an honest result card and a session log you can clear.

The live table

Your DM reads a short code off Gnasher's Grimoire; you type it in. Your rolls appear at the table, the initiative order lights up when it's your turn, and handouts land in your Journal.

Phones sleep. Fine.

When your screen dozes off, your seat is held. The Satchel rejoins by itself when you wake it, and anything you missed, even a private whisper from the DM, is already waiting.

Yours, forever

Everything lives on your device. Export a .satchel file any time to back up or move phones. No account to lose, nothing to cancel.

Install to rolling, in ten steps

The same walkthrough lives inside the app, under How to use on your character shelf.

Install it. Open the Satchel. iPhone: Safari's Share button, then Add to Home Screen. Android: Chrome's menu, then Add to Home screen, then Install.
Or tap "Try a sample hero" on the empty shelf: a ready-made Fighter, every number real, so you can tap things before you build anything.
Make a character with + New Character: name, class, level, and the Standard array button for instant ability scores. Three minutes, playable.
Or bring your D&D Beyond character. Set it to Public on dndbeyond.com (Manage, then Character Settings, then Privacy), then paste your character's link into the Satchel's Import. It opens your data page in a new tab; select all, copy, tap Paste, done. You carry your own data; the Satchel never fetches it for you.
Or bring your Foundry character: right-click the actor, Export Data, and feed the .json to Import.
Roll by tapping. Any ability, save, skill, or attack rolls itself, bonus included. Set Adv or Dis on the dice tray first when it matters.
Run the fight from the Fight tab. Damage, Heal, and Temp HP live inside the hit-point plaque; at 0 HP it becomes death saves, and a Healed button waits there for your cleric. Conditions, slots, hit dice, class resources, and rests are all one tap.
Level up in the Study. Tap Level up: the Satchel shows what the level brings, asks for your subclass or your Ability Score Improvement or feat, files the features you gain, and moves every number that should move.
Join the table. Tap the wax seal, type the short code your DM reads out, tap Join. The seal glows when you're linked and remembers the code for next week.
Play. A YOUR TURN banner takes the top of the screen when the fight reaches you. DM handouts and whispers land in your Journal, where you can rename, tag, and annotate them.
Keep notes. Journal tab: dated Session Notes, free Campaign Notes pages, and your handout shelf.
Back it up. Journal tab, Export .satchel. One small file is your whole character; Import brings it back on any device.

For DMs: light the table in five steps

You host from Gnasher's Grimoire; your players just point their Satchels at it.

Open Gnasher's Grimoire and tap Theater in the menu bar.
Tap Open the table by code and read the code aloud. Each player types it into their Satchel's wax seal. (No venue internet? Same room mode or your phone's hotspot.)
Run combat exactly as you always do; the tracker drives every paired Satchel by itself, turn banners included.
Push handouts (text or images) from the Theater panel; pick one name in the To row to whisper it privately.
Phones that doze show as resting seats. Keep playing; they catch up the moment they wake.

The other half of the table

Your DM runs it from the Grimoire

Gnasher's Grimoire is the free binder that holds every adventure, summons any table or monster in a keystroke, and drives the initiative your Satchel watches for. The two are built for each other.

Free, offline DM app: holds your whole library.
Hosts the live table your Satchel links into.
The War Table your initiative bar is reading from.
