An iOS 26 educational peptide-tracking app. Pick the compounds you're tracking, learn about them, build a schedule, log doses, keep a diary, read lab work, and ask an AI grounded in your own stack — in a calm, warm, "fields"-inspired interface.

Vita is a personal learning + tracking tool, not medical advice and not a medical device. AI suggestions and every dosing value are educational ranges, never instructions, and can be wrong. Many compounds referenced here are prescription-only or regulated and vary by jurisdiction. The bundled catalog is unverified. Not affiliated with any vendor. Consult a licensed clinician.

Four tabs — Today · Stack · Diary · Chat — plus labs, a reconstitution calculator, and settings.
- Today — a time-adaptive home: a dynamic headline, an "Up next" focus card with a live countdown, an expanding Morning/Midday/Night control, and full-size "pins" you tap to log (the signature north-star tap animation). Streak, day-complete, and rest-day moments; a quiet "as needed" (PRN) card.
- Stack — your compounds, each with a detail screen (Dose / Timing / Why) showing the active dose, a cycle ribbon ("On · week 3 of 8"), and a titration ladder. Add from a searchable catalog (~58 compounds, 6 categories) with a prescription (℞) badge on clinician-supervised ones.
- Scheduling depth — daily / every-other-day / weekly / as-needed, plus cycles (on/off blocks that rest and never go overdue) and titration (dose stepping over time), all derived live (no event materialization).
- Diary — a daily check-in on a signature 1–10 slider (energy/sleep/mood/libido) + side-effects + note, weight & measurements (with Apple Health backfill), and a Swift Charts trend with drag-scrub.
- Chat — a streaming assistant grounded in your stack, goals, profile, Health, diary, and labs; it can suggest stack changes you confirm in a sheet.
- Labs — scan a photo or PDF of bloodwork; Claude vision reads the values; review and save panels with high/low flags and a "vs last" delta.
- Reconstitution calculator — "draw to X units" (U-100/50/40), mg↔IU, with calm warnings.
- Notifications — local dose reminders, actionable from the lock screen (Log / Skip / Snooze), that disappear once a dose is logged.
- AI protocol generation — onboarding turns your goals + picks into a starter stack via Claude (with a rule-based fallback when offline / no key).
See ARCHITECTURE.md for how it's built and ROADMAP.md for status + what's next.
- iOS 26, SwiftUI, Swift 6 (strict concurrency), Xcode 26. Light mode only (tokens are dark-ready).
- SwiftData local-first store (CloudKit-legal models; sync designed but not yet enabled).
- XcodeGen — the
.xcodeprojis generated fromproject.yml(and gitignored). - Claude Opus 4.8 via the Anthropic Messages API (raw
URLSession, no SDK): forced tool-use for structured output, vision for labs, SSE streaming for chat. - HealthKit (read-only), Swift Charts, PDFKit, local UserNotifications.
- 323 unit tests and 8 UI tests, no third-party runtime dependencies.
Requirements: macOS with Xcode 26 (iOS 26 SDK), and XcodeGen (brew install xcodegen).
git clone https://github.com/advegaf/vita.git
cd vita
# 1. Set up local config (key + signing team — both optional for the simulator)
cp Config/Secrets.example.xcconfig Config/Secrets.xcconfig
# edit Config/Secrets.xcconfig — see CONTRIBUTING.md
# 2. Generate the Xcode project
xcodegen generate
# 3a. Build + run the tests on a simulator (no key or signing needed)
xcodebuild -project Vita.xcodeproj -scheme Vita \
-destination 'platform=iOS Simulator,name=iPhone 17 Pro' test
# 3b. Or open and run
open Vita.xcodeprojThe app runs with no API key — onboarding falls back to a rule-based starter stack, and you can explore every screen. AI features (protocol generation, chat, lab reading) need an Anthropic key in Config/Secrets.xcconfig. Building for a physical device needs your Apple Developer Team ID (also in Secrets.xcconfig) — see CONTRIBUTING.md.
If you're picking this up:
- Read ARCHITECTURE.md — it maps the layers and where everything lives (the data layer, the Claude integration, the design system, the scheduling engine).
- Skim ROADMAP.md — what's shipped (milestones M0–M10.1) and the prioritized backlog (next up: M11 — lab marker-over-time trend charts).
- Build it on the simulator first (no key/signing needed) to see it run, then wire your own Anthropic key + signing team for the full experience.
CLAUDE.md/AGENTS.mdcapture the build loop, conventions, and gotchas — if you continue with an AI coding agent (this project was built with one), point it there first.- Good first tasks are filed as GitHub issues (M11, CI, an SPM module split, an a11y pass, a distribution/proxy path).
