How to Build a Mobile App for Daily Planning and Prioritization
A step-by-step guide to plan, design, and build a mobile app for daily planning and task prioritization—from MVP features to notifications, testing, and launch.
A step-by-step guide to plan, design, and build a mobile app for daily planning and task prioritization—from MVP features to notifications, testing, and launch.
Before you design screens or pick a tech stack, get specific about who you’re helping and what they’re trying to accomplish in a normal day. “Everyone who wants to be productive” is too broad—daily planning looks very different for a student, a nurse on shifts, a freelancer, or a parent juggling school pickups.
Choose one primary audience for v1 (you can support others later):
Write a one-sentence promise like: “Help solo professionals plan a realistic day in under 3 minutes.” That promise should guide every feature decision.
Most daily planning apps fail because they don’t solve the painful parts:
Talk to 8–12 people in your target group and listen for repeated phrases. Those phrases become your product language.
Decide what your app is mainly for:
Choose measurable outcomes for the first release, such as:
Clear users, pains, and success metrics prevent feature creep—and make v1 feel purposeful.
A planning app sticks when it makes one repeated behavior feel effortless. Before features, define the “loop” a user completes every day (or at least every workday). This loop will shape your home screen, navigation, and north-star metric.
Keep them concrete and time-bound so the team can debate less and build faster:
Capture: A single, always-available input. Fast add now; optional details later. The goal is zero friction, not perfect structure.
Prioritize: Turn raw tasks into a short list. This can be as simple as “Top 3” + “Later,” or a gentle method like an Eisenhower-style important/urgent choice (you’ll pick the exact method later).
Schedule: Convert priorities into a realistic plan. Time blocking works well here: assign 1–3 blocks for deep work, plus a flexible “admin” block for smaller tasks.
Do: Show “Now” and “Next” clearly. Reduce decisions: one primary action (“Start block” / “Mark done”) and quick defer (“Move to later today”).
Review: End-of-day takes ~60 seconds: done items, moved items, and one reflection prompt. This is where the app feels like progress, not pressure.
Write these down explicitly to protect the loop:
Keep it short and visible to everyone:
This brief is your guardrail: if a feature doesn’t strengthen the loop, it waits.
Your v1 should help a person do one thing exceptionally well: capture tasks quickly, decide what matters today, and follow through. If the app needs a tutorial just to reach a usable daily plan, the MVP is too big.
These are the features that make the loop possible:
These add value, but they also add UI, edge cases, and settings screens:
| Area | MVP (v1) | Later |
|---|---|---|
| Capture | Quick add + basic inbox | Widgets, voice capture |
| Organize | Priority + due date | Tags, projects, templates |
| Plan | “Today” list | Time-blocking, drag-and-drop schedule |
| Remind | One reminder per task | Smart nudges, multiple reminders |
| Sync | Local/offline basics | Calendar sync, cross-device sync |
Treat this as a contract: if a feature isn’t in the MVP column, it doesn’t ship in v1.
Prioritization should feel simple, familiar, and optional—users shouldn’t feel forced into a system they don’t understand.
For v1, pick one method as the default and make it the least effort to use. The most universal option is High / Medium / Low because it’s instantly understood and works across work, home, and school.
Keep labels short (“High”), but clarify meaning with tooltips like:
Some users think in urgency, others in impact. Supporting a couple of additional modes can help without bloating the UI:
A strong pattern is “one active method at a time,” selectable in Settings. That way, the same task doesn’t end up with conflicting priority signals.
Avoid abstract explanations. Show 2–3 concrete examples that match your target audience:
This takes under a minute, but dramatically reduces misuse (like marking everything High).
A Focus view should show only what the user decided matters most—e.g., High priority tasks or the top-left Eisenhower quadrant. Keep it calm: a short list, a clear next action, and a quick way to mark done.
Even as you add features later, the Focus view should remain the “home base” that makes prioritization feel worth the effort.
A daily planner succeeds when “making a plan” feels quick, and “changing the plan” feels painless. Decide early whether your day view is a simple list, time blocks, or a hybrid.
A simple day list is best for users who think in priorities (“top 3 today”). Time blocking fits users who think in calendar time (“9–10: write report”). Many successful apps offer both views over the same data:
If you support time blocking, treat it as “planned intention,” not a hard promise—people need to adjust without feeling like they failed.
Make time feel predictable by separating:
This structure reduces clutter and makes “planning tomorrow” a small step rather than a full reorganization.
A deadline answers “must be done by when.” A time block answers “when will I work on it.” Let tasks have one or both, and show conflicts clearly (e.g., a deadline today with no planned slot).
Support recurring tasks for habits, bills, and weekly routines. Keep recurrence simple (daily/weekly/monthly) and allow “skip once” without breaking the series.
Plans change. Offer:
The easier rescheduling is, the more often users will keep planning instead of abandoning the app.
Great planner UX is less about “more features” and more about fewer decisions per tap, clearer status, and a flow that matches how people think: capture now, organize later, act today.
Design your first version around a small set of screens that each answer one question:
Avoid mixing planning and editing everywhere. For example, the Today view should emphasize action (start, snooze, complete), while deeper edits live in Task details.
Treat capture like a note: title first, details later. A single input field plus an optional “Add details” affordance is often enough.
If you offer extras (due date, priority, tags), keep them as quick chips or a bottom sheet—not mandatory form fields. Users who can’t add a task in two seconds will postpone, then stop trusting the app.
People scan. Your UI should clearly separate:
Use color + text, not color alone (“High priority” label, icons, or weight). Reserve the strongest emphasis for “what needs attention now,” not for every decorative element.
Accessibility is usability:
Also design for one-handed use: primary actions near the bottom, and destructive actions (delete) behind a confirmation step.
A planning app feels “smart” when its data model is simple, consistent, and flexible enough to support real life. Store the minimum structure needed for planning (tasks), prompting (reminders), and committing time (schedule blocks), while leaving room for future organization features.
Task is the center: something the user might do.
Around it, add:
Make title required; almost everything else can be optional so capture stays fast.
Suggested fields:
Use explicit states so the UI can show “what’s next” without guessing:
Assume users will add/edit tasks without service. Store changes locally as operations (create/update/complete). When reconnecting, sync and resolve conflicts predictably:
Notifications are a power tool: they can keep people on track, or make them uninstall your app. The goal is to be helpful at the exact moment action is possible—without constant buzzing.
Start with three clear categories and make them easy to understand:
If you can’t explain why a notification helps the user do something right now, it probably shouldn’t ship in v1.
Add notification controls in onboarding and in Settings (not buried three screens deep). Let users set:
Default to fewer notifications than you think—people can opt in to more.
When several tasks trigger at once, group them into a single summary (“3 tasks due this afternoon”) with an option to expand in-app. Use smart defaults like:
Assume many users will disable push notifications. Add backup cues:
That way, the app still feels reliable even without push.
Integrations can make a daily planning app feel “native” to someone’s routine—but they also multiply complexity. For v1, pick the few that reduce daily friction the most, then design the app so you can add more later.
A practical v1 approach is one-way read from the device calendar: show events in the daily plan so users can time-block around real commitments. Writing tasks back into the calendar is powerful, but it creates tricky questions (which calendar, what happens on edits, how to resolve conflicts). If you do write-back in v1, keep it optional and clearly labeled.
Document edge cases early:
Widgets are often the fastest win: a “Today” widget (next 3 items + add button) and a “Quick add” widget cover most needs without deep navigation.
For voice assistants, keep v1 simple: support a single intent like “Add task” with a default list and minimal parameters. The goal is capture, not perfect categorization.
Even basic CSV export (tasks + due dates + notes) and a simple local/Cloud backup option build trust. Import can come later; exporting is usually enough to remove the fear of getting stuck.
Request calendar/notifications/microphone access only when the user triggers the feature. Add one sentence explaining why (e.g., “We need calendar access to show your meetings in Today”). This increases acceptance and reduces support issues.
A daily planning app wins or loses on speed and reliability. Your build plan should keep scope tight, ship an MVP, and leave room to grow without rewriting everything.
You have three practical options:
Choose based on where your earliest adopters are, not what’s “best” in general.
For v1, aim for: UI → app logic → local database, with sync as optional.
Keep your data model and app logic independent from the UI so you can change screens without breaking core behavior.
If you want to validate the workflow quickly—Inbox → Today → Review—consider building a clickable, working MVP first and iterating with real users. Platforms like Koder.ai can speed this up by letting you describe screens and flows in chat, generate a full app (web, backend, and even mobile), and then export source code when you’re ready to take over the codebase in a traditional repo.
This approach is especially useful when you’re still learning what “planning in 3 minutes” actually means for your target audience.
Productivity apps are opened dozens of times a day. Optimize for:
For each feature (e.g., “Add task,” “Plan my day,” “Reschedule”):
This checklist prevents half-finished features that look done but fail in real daily use.
Testing a daily planning app isn’t just about “no crashes.” You’re validating a habit: people will only return if the loop feels quick, predictable, and trustworthy.
Create concrete scenarios that mirror real mornings and messy afternoons. Aim to cover the full loop (add → prioritize → plan → complete) under different conditions.
A good set of scenarios includes:
Include “interruptions” (new urgent task mid-day) and “failure” states (user abandons planning halfway, then returns).
Notifications often fail in the real world, not in a simulator. Test reminders across device states:
Confirm the user-facing behavior matches what you promise (sound, banner, lock screen) and that missed reminders are handled gracefully.
Recruit 5–8 target users and give them tasks using a clickable prototype first, then a test build. Watch for hesitation: where do they tap first, what do they expect to happen, and what feels “too much work” for daily use.
Set a simple triage process (severity, reproducibility, owner, target release) and keep a release checklist: critical flows pass, notification checks complete, offline behavior verified, analytics events firing, and a rollback plan ready.
A daily planning app only becomes “real” when people try it on busy days. Treat launch as the start of learning, not the finish line.
Start with a beta group that matches your target users (e.g., students, shift workers, managers). Keep it intentionally small (50–200 people) so you can respond quickly.
Set up a simple feedback loop:
Make your beta onboarding explicit: “Use it for 7 days, then tell us what broke your routine.”
Your screenshots should highlight the core promise in 3 seconds:
Use plain-language captions like “Plan your day in 60 seconds” and “Know what matters next.”
Track a few metrics that reflect habit formation:
Start with upgrades that deepen daily use:
If you have tiers, keep upgrade messaging tied to outcomes and clarify it on /pricing.
If you’re building in public, you can turn lessons from your MVP into user acquisition. For example, Koder.ai supports an earn credits program for creating content about what you built and a referral link flow—both useful if you want to keep experiments running while controlling costs across free, pro, business, and enterprise tiers.
Start by choosing one primary user group for v1 (e.g., students, professionals, caregivers, solo operators) and write a one-sentence promise like: “Help solo professionals plan a realistic day in under 3 minutes.”
Then validate the top 3 pains with 8–12 interviews (common ones are forgetting tasks, unclear priorities, and unrealistic schedules).
A reliable loop is: capture → prioritize → schedule → do → review.
Design your navigation and home screen around completing this loop quickly (e.g., Inbox for capture, Today for action, Review for reflection). If a feature doesn’t strengthen the loop, defer it.
Keep v1 focused on the minimum needed to complete the loop:
Limit to ~3–5 core screens and ship smart defaults instead of lots of settings.
Pick a default that takes one tap and is instantly understood—High / Medium / Low is usually the safest.
If you add alternatives (Eisenhower, Effort vs. Impact), use one active method at a time (switchable in Settings) so tasks don’t end up with conflicting priority signals.
Treat deadlines and scheduled blocks as different concepts:
Let tasks have either or both, and highlight conflicts (e.g., deadline today with no planned slot). This prevents “calendar clutter” while still supporting realistic planning.
Make capture feel like writing a note: title first, details later.
Use quick controls (chips/bottom sheet) for optional fields like due date and priority. If task entry becomes a form, users will delay capture—and stop trusting the app.
Use a small set of clear types:
Add quiet hours, conservative defaults, grouping (“3 tasks due this afternoon”), and easy snooze. Also provide an in-app notifications list so the app stays useful when push is disabled.
Keep the model small and consistent:
For offline-first, store changes locally and sync later with predictable conflict rules (e.g., last-write-wins for text fields, operation-based merges for tag/reminder sets).
For v1, one-way read calendar sync is often best: show events so users can plan around meetings without writing back.
Document edge cases early:
Ask for calendar permission only when the user enables the feature, and explain why in one sentence.
Measure habit formation, not vanity metrics:
Use a small beta (50–200 target users), add an in-app feedback button, and iterate on a predictable cadence. If you add templates later, keep them tied to outcomes (see /blog/productivity-templates).
