WhatsDab - Chat on the Schedule I Phone

🛟 Need help or found a bug? Get support at support.doodesch.de/whatsdab.

Text the people in your lobby from the phone you already carry. Threads, unread counts, group and one to one chat, in both orientations. Written as three web files on Sideload, which is also the mod to read if you want to build your own phone app.

Players

WhatsDab shows up as its own app on the in game phone and texts the people actually in your Steam lobby. One thread per player plus a group thread, with a contact list and the conversation side by side, a search filter, unread counts, coloured avatars, day separators, timestamps, a delivery tick, a typing indicator and a send bar. Turn the phone with the game's own rotate keys and it switches to portrait, one pane at a time.

Any lobby works - plain co-op, one a gamemode opened, one from the main menu. It rides the same Steam lobby chat the game already uses, so there is no server and no other mod needed. Everyone in the lobby needs WhatsDab to take part.

Conversations stay in memory for the session and are never written to disk. Leave the lobby and they are gone. It is safe to remove at any time.

Mod authors

This is the mod to copy. It references no Unity assembly, no IL2CPP interop and not Sideload itself - only MelonLoader plus the single file Sideload.Api shim, which finds the host by reflection. Game logic in C#, the entire interface in index.html / app.css / app.js, shipped as one DLL.

Core.cs                 one Apps.Register call, then only data
Chat/ChatBackend.cs     the ENTIRE seam to the interface: 5 calls in, 1 event out
Assets/whatsdab/        the app

The same screen exists as hand built uGUI elsewhere: 781 lines of C# there against 518 lines of HTML, CSS and JavaScript here, with more features. What the lines hold matters more than how many: one version computes a chat bubble's height from text measurements, the other writes align-self and max-width.

Any file under Mods/whatsdab/ overrides the copy embedded in the DLL, so you can edit the app without rebuilding. preview.html in the source tree runs the shipped app in Chrome without launching the game.
