Tertiary Planner — AI To-Do & Planner for iOS

A native iOS app for managing to-dos and appointments by voice or touch. Speak naturally — "Lunch with Sam tomorrow at 1pm" — and on-device intelligence turns it into a scheduled appointment; "Buy groceries" becomes a to-do. Appointments appear in a built-in calendar, checked items auto-archive, and everything can sync to your personal iCloud.

Tertiary Planner is available on the App Store. Version 1.0 ships with on-device storage; iCloud sync (already implemented in the codebase) is enabled in a v1.1 update once the CloudKit container provisioning is finalized.

Features

• 💬 Assistant chat — the app's front door: tell the assistant what you need, by text or voice, and it drafts a nicely worded to-do or appointment and saves it instantly (with undo).
• 🍎 Apple Intelligence on-device — on iOS 26+ devices with the system model available, the assistant uses Apple's FoundationModels framework to classify and word entries; everywhere else it falls back to the deterministic parser. Both paths are fully local.
• ✅ To-dos & appointments in one list — add either from a single, smart form.
• ✏️ Tap to edit — tap any item in the Planner or Calendar to fix a typo or change its title, notes, type, or date in the same form used to create it.
• 🎙️ Voice capture — tap the mic, speak, and native iOS speech-to-text transcribes it.
• 🧠 On-device "AI" parsing — detects dates/times, classifies task vs. appointment, and cleans up the title automatically (no network, fully private).
• 📅 Built-in calendar — appointments show on a graphical month calendar with per-day and upcoming lists.
• 📥 Auto-archive — checking off an item moves it to the Archive automatically; uncheck to restore.
• ☁️ iCloud sync — SwiftData + CloudKit mirrors your data to your private iCloud database across all your devices.
• 💬 Feedback & About — house-style tabs (WhatsApp feedback, developer info, version).

Tech Stack

• UI: SwiftUI, Human Interface Guidelines, SF Symbols, Dynamic Type, dark-mode theming.
• Persistence & sync: SwiftData with automatic CloudKit mirroring (private database).
• Voice: SFSpeechRecognizer + AVAudioEngine (prefers on-device recognition); the audio engine is created lazily so no microphone prompt appears until dictation is actually used.
• Intelligence: IntentAssistant uses Apple's on-device FoundationModels (Apple Intelligence, iOS 26+) for intent classification and title wording, falling back to SmartParser (NSDataDetector + NaturalLanguage). Dates always come from the deterministic parser so clock math never hallucinates.
• Project: generated from project.yml via XcodeGen.

Getting Started

# Requirements: Xcode 16+ (iOS 17 SDK), XcodeGen (brew install xcodegen)
xcodegen generate
open PlannerApp.xcodeproj

Build & run on the iPhone 17 Pro simulator, or select your device.

Enabling iCloud sync on a device

The default device build installs with local storage. To turn on iCloud sync:

1. In Xcode → Settings → Accounts, add your Apple ID (Apple Developer Program team).
2. Select the PlannerApp target → Signing & Capabilities; Xcode registers the iCloud + Push Notifications capabilities declared in PlannerApp.entitlements and creates the iCloud.com.tertiaryinfotech.plannerapp container.
3. Ensure CODE_SIGN_ENTITLEMENTS points at PlannerApp/PlannerApp.entitlements in project.yml, then rebuild.

Permissions

The app requests Microphone and Speech Recognition access only when you first use voice capture. Transcription prefers Apple's on-device engine where supported.
