Stacker: Three Things a Day

Stacker is a clean, ad-free daily planner for iPhone and iPad — built for people who are tired of bloated todo apps that drown them in a backlog. Stacker forces a simple ritual: pick three things that would make today a win. Check them off as you go. Reflect in the evening. The streak only grows on days when all three are done. Key features: • Three-item stack — no more, no less. Limit your day to what actually matters. • Morning + evening prompts — gentle local notifications nudge you to plan in the morning and reflect at night. Notifications are local-only; nothing leaves your device. • Energy + time-of-day anchors — tag each item with energy (low/med/high) and a time anchor (morning/midday/evening/anytime) so your day has a natural shape. • Daily themes — Focus, Ship, Learn, Rest, Explore, Connect. Set the tone for your day. • Reflection note — capture how the day actually went, one note per day. • 14-day completion chart — see your last two weeks at a glance, powered by Swift Charts. • Streak + perfect-day counter — a streak only grows on days you complete all three. No "partial credit", no streak-saver gimmicks. • Home Screen widget — small + medium widgets show your top three at a glance, with progress and theme. • iPhone + iPad universal — designed for iOS 17 with native SwiftUI. Privacy by design: Stacker collects nothing. No analytics, no ads, no tracking, no account. All data stays on your device. Notifications are scheduled locally by iOS, never via a push server. Stacker is for you if: • You want a planner you'll actually open every day. • You are tired of a 200-item backlog that follows you forever. • You want to build a daily completion habit, not chase tasks. • You care about a beautifully boring app that respects your time and your data.
