Daygrid | Native iOS Task Manager App in SwiftUI

Important Cost Disclosures (Not Covered by the Purchase Price)

Apple Developer Program – $99/year. This app includes StoreKit 2 In-App Purchase subscriptions. Building to a physical device and distributing the app (including creating and testing the IAP products) requires an active paid Apple Developer Program membership at $99 USD per year. This ongoing cost is not included in the purchase price.
Supabase – ongoing costs beyond the free tier. The optional cloud features use Supabase (Auth plus Edge Functions). Supabase offers a free tier, but usage that exceeds the free tier incurs ongoing subscription costs billed by Supabase. These external costs are not included in the purchase price. The app is fully functional offline without Supabase, and you can ship it without any backend.

Daygrid is a complete, production-ready native iOS task manager built entirely in SwiftUI. It combines a minimalist daily to-do list, a custom inline calendar, a “Life in Weeks” visualization, task timers, a meditation timer, a pixel drawing canvas, and a bucket list – with optional cloud sync via Supabase and In-App Purchase subscriptions via StoreKit 2.

Demo Instructions

The app is fully functional offline out of the box. Build and run in Xcode and you can immediately add tasks, use timers, browse the calendar, view Life in Weeks and draw. Email sign in requires only a free Supabase account and the two keys documented in the documentation; all other cloud features (cross-device sync, weekly email report) additionally require the Supabase Edge Function endpoints, whose full API contract (URL pattern, methods, request and response shapes) is documented in the included documentation so you can implement or extend them on your own Supabase project. Pro features are gated behind StoreKit subscriptions, which you can test free of charge in the Xcode simulator using the included StoreKit configuration file.
