For Martin, not for a lodge. Four tabs along the bottom. The You tab has the app's own role switcher: change it and watch the Officers room and Lodge admin appear and disappear.
Read line by line off /Users/martinmendoza/tino/coding/lodge-app/: app/(tabs)/index.tsx, chat.tsx, brothers.tsx, you.tsx, plus lib/theme.ts, rules.ts, calendar.ts and degrees.ts. Colours, wordings, degree names, office names, filter chips, empty states and the diamond proficiency mark are all the app's own.
Rebuilt 2026-09-01 after Martin caught the You tab. The first version was drawn from a grep for capitalised text, so everything the app renders through its own components was invisible to it and all four tabs came out wrong. Home had lost the whole-month calendar, which is the thing Martin explicitly asked for, plus the crest and the birthdays; Chat was a list of rooms instead of one screen with chips; Brethren had lost search, the filters and the degrees; You had lost the entire profile card.
What this is not: a drawing of the built app, not the built app. Nothing talks to a database. The real one is in no app store, has no lodge in it, and nobody has used it.
