Install the beta

Anyone can join. Android and web. Free.

Terry the Tiny Tarrasque is nervous about strangers with phones, but the install takes about two minutes. Pick your way in:

Android: Google Play

Anyone can join. Google makes new developers run a tester program before a public listing, so on Android it's three taps. In a browser it's none. Use the Google account that's signed in to Play on your phone for all three steps.

1. Join the testers group. Tap Join group on the page that opens.
   Join the testers group
2. Become a tester. Tap Become a tester on the page that opens.
   Become a tester
3. Install from Google Play. If Play says the app isn't available, wait a few minutes after step 2 and try again.
   Open Google Play

Please keep the app installed for at least two weeks. Google needs 12 testers for 14 days before the app can go public, so every install helps.

Tested the alpha or a beta APK? Back up your heroes first (Settings → Back up and import → Back up now), then install from Google Play. If Play asks you to uninstall the old app first, import your backup afterwards (Settings → Back up and import).

On the web

Open tiny-tarrasque.expo.app in any modern browser. Your characters stay in that browser, so use the same browser each time and make a backup (Settings → Back up and import → Back up now) before clearing browser data.

iPhone

There is no iPhone app yet. On iPhone and iPad, use the web version at the link above.

Updates

• Most fixes arrive over the air: open the app twice and you have them. Settings → About shows which update you are on.
• Bigger updates come through Google Play, like any other app.
• The web version updates itself when you reload the page.

Your characters and backups

There is no account and no cloud sync in the beta. Characters live on your device. Use Settings → Back up and import → Back up now to save them to a file, and keep a copy somewhere safe, especially before uninstalling the app.

What stands out

• Turn bar. Action, bonus action and reaction tick themselves off as you attack and cast, so you see what you have left this turn. Extra Attack and Action Surge are counted for you.
• Companions. Familiars, steeds and summons get their own cards on the sheet.
• Homebrew packs. Make your own species, classes, subclasses, spells, items and feats in the app, or import a pack from a file. The app ships no homebrew of its own.
• Dead and Retired heroes. Mark a hero Dead or Retired and keep them in your list instead of deleting them.
• Print sheet. Menu → Print sheet gives you a paper-friendly version of your character, with a spells page for casters.

What is missing on purpose

• Rules content is the open System Reference Document 5.2.1 (the 2024 rules), with the 2014 rules (SRD 5.1) as an option per hero. All 12 classes go from level 1 to 20, with the one subclass per class that is in the open rules. Anything else you add yourself as homebrew.
• The homebrew editor is in beta: make species, classes, subclasses, spells, items and feats, or import a pack from a file. The app ships no homebrew of its own.
• No account, no cloud sync, no party tools yet. Sharing rolls to a Discord channel is optional and off until you set it up.
• No iPhone app (see above).
• Resting is a quick menu (Rest, then Short or Long), not a single tap.

Reporting problems and ideas

• Join the tester Discord: tinytarrasque.com/discord
• Or use Menu → Send feedback in the app (also in Settings → Feedback), or write to hello@tinytarrasque.com. Say what you did, what you expected and what happened.

Crash reports and usage stats are optional and off until you agree. See the privacy policy.
