VitalStackFit App Guide

If you're new, this is what good setup looks like.

If Apple Health already has historical data, VitalStackFit can generate initial metrics and trend cards right away after permissions are granted.

Day 1 Checklist (5 minutes)

1. Allow key Apple Health permissions.
2. Open Overview and save your first Daily Check-In.
3. Enable weekly reminder (optional).
4. Return tomorrow and repeat one check-in.

Most Important Permissions First

For quickest value, prioritize:

• Sleep
• HRV
• Resting Heart Rate
• Heart Rate
• Activity (active energy + steps)
• Mindful minutes

Optional but useful:

• Environmental sound
• Workouts
• Respiratory rate
• Blood oxygen

What to Do If Scores Are Low

• Recovery low: protect sleep timing tonight.
• Focus low: schedule one quiet 45-minute focus block.
• Stress low: add one short breathing or reset block.
• Consistency low: set planned tasks early, then log completed tasks by day end.

How to Trust Scores Over Time

• Day 1-2: early directional signal only.
• Days 3-7: trend becomes more stable.
• Week 2+: better confidence and clearer personal patterns.

Tip: don't react to one day. Review 7-day direction.

Daily Check-In saves only your latest check-in for that calendar day.

VitalStackFit can use Apple Health data such as:

• Sleep
• Heart rate
• Resting heart rate
• HRV
• Heart-rate recovery
• Respiratory rate
• Blood oxygen
• Environmental sound exposure
• Active energy
• Steps
• Mindful sessions
• Stand hours
• Workouts

Apple Watch is optional.

If you use Apple Watch, your trend depth is usually better.

If a metric has limited history, you may see “Not enough data” until more samples are available.

Stress

How balanced your recent strain pattern appears over time.

Consistency

How regularly you sustain your routine and follow-through behavior.

• 40-59: Needs attention
• 0-39: Recover and reset first

Main Takeaway

The single most important thing the app wants you to notice right now.

Score Cards (Recovery, Focus, Stress, Consistency)

A quick snapshot of the four main parts of your weekly pattern.

Trend Card

Shows whether your readiness is moving up, down, or staying roughly steady over recent weeks.

Daily Check-In

A quick self-report that helps the app personalize your trend view over time.

For each calendar day, VitalStackFit stores the latest self check-in entry.

Daily Patterns

Highlights timing windows and repeated behaviors so you can spot when your days are calmer, louder, higher-effort, or lower-effort:

• Calmest vs loudest periods
• Higher vs lower heart-rate windows
• Resting vs active timing tendencies

Weekly Outcome Report (Pro)

Summarizes what changed this week and which signals likely drove that change.

Long-Range Analytics (Pro)

Shows 30/90-day movement so you can see bigger shifts, not just short-term noise.

Predictive Alerts (Pro)

Flags possible downside or upside windows based on your recent direction.

Experiment Engine (Pro)

Run controlled habit experiments and measure whether they actually move the needle for your trend.

• Confidence-scored results: each experiment is evaluated with effect size, sample confidence, and delta tracking.
• Smart recommendations: the app learns which experiments have worked for you before and ranks them as Best Match, Worked Before, Worth Retesting, or Low Proof.
• Experiment history: see how a habit performed across multiple attempts with success rates and evidence summaries.

Brag Cards V3 (Pro)

Brag Cards V3 are premium, social-ready visuals that automatically adapt to the story your real weekly trend is telling.

When Persona Sharing is enabled, your selected card can also be paired with a branded animated companion built for the same share story.

Persona Video

Dynamic Themes

VitalStackFit automatically selects one of four themes:

• Consistency: steady routine and stable momentum
• Comeback: clear upward movement from a softer phase
• Peak: strong readiness week and high-performance rhythm
• Calm: lower-noise, recovery-friendly pattern

Outcome-First Card Logic

Brag Cards prioritize meaningful outcomes in this order:

1. Weekly outcome improvement
2. Milestone achievement
3. Check-in streak achievement
4. Weekly plan progress (if still in progress)

What Appears on Each Card

• Current readiness score
• 7-day trend visualization
• Highlight stats such as week delta, score, streak, and actions done
• Badge strip for milestones, streak, and team or progress context
• Share-ready tags

Free vs Pro Sharing

• Free: quick text share
• Pro: premium visual Brag Card export

Notes

• Card content can differ by user and week based on available data.
• If data is limited, cards may show early progress context rather than a completed outcome.
• Brag Cards summarize informational wellness trends only and are not medical advice.

VitalStackFit Pro now includes a Persona companion for Social sharing. Persona turns your selected share mode into a polished animated visual that matches the same story your card is telling, while staying clearly informational and non-medical.

What Persona adds

• A branded animated Persona preview in the Social section.
• Visual states that match your selected share context: Today, Yesterday, or Weekly.
• Branded export overlays with app name, app icon, selected mode, and a short caption.
• Multiple export styles so users can choose what they want to share.

Available share modes

• Today: an in-progress view of today's current momentum.
• Yesterday: a completed full-day recap.
• Weekly: a stronger summary of recent momentum and wins.

Export styles

• Card Only: share the selected brag card by itself.
• Card + Persona: share the brag card together with a looping Persona video.
• Video Only: share only the Persona video.

What appears in Persona video

Persona exports can include:

• VitalStackFit branding.
• The selected share mode.
• A short context subtitle.
• A state label such as Recovery, Steady, Strained, Calm, or Celebration.

Persona style setting

Users can choose a Persona style inside Help. This changes how the Persona appears in the Social section and persona-enabled exports.

Important note

Persona is a visual storytelling layer for sharing progress. It does not change the app's scores, and it does not provide medical advice, diagnosis, or treatment.

Loudest Window

Time of day with highest environmental sound trend in your selected range.

Quietest Window

Time of day with lowest environmental sound trend in your selected range.

Higher HR Window

Time period where average heart rate trends higher than your day baseline.

Lower HR Window

Time period where average heart rate trends lower than your day baseline.

Resting vs Active Timing

Approximate timing patterns that indicate when your days are calmer vs more active.

These are behavioral trend observations only.

They are not medical conclusions.

Change

How your selected trend moved during the experiment period.

Confidence

How reliable the current signal looks with available data.

Signal Strength

How noticeable the pattern difference appears right now.

Recommendation Badges

After running experiments, each one gets a recommendation badge based on your personal history:

• Best Match: strong current signal and good prior success rate.
• Worked Before: historically helpful based on past runs, worth leaning on when the same signal dips.
• Worth Retesting: mixed results so far, a cleaner 7-day run would help settle the pattern.
• Low Proof: has not reliably helped yet, only repeat when the signal clearly points to the same issue.
• First Run: no prior history, treat this week as evidence gathering.

Experiment History

Below current experiments, you can see past results with their badges and evidence summaries. The more experiments you complete, the smarter recommendations become.

What to do

• Keep experiments simple.
• Run one consistently for at least a week.
• Compare trend direction, not one-day spikes.
• Check recommendation badges to see which experiments have the strongest personal evidence.

Apple Intelligence is an optional layer in VitalStackFit that helps turn trend data into simpler, easier-to-read summaries. It is designed to help you understand what changed this week, what stands out today, and what to focus on next without changing the app's core experience.

Core scores, trend cards, and analytics still work without Apple Intelligence. The app remains fully usable even if these features are not available on your device.

What Apple Intelligence adds

• A short daily readiness brief that explains your current trend state in clearer language.
• A weekly narrative summary that highlights notable wellness trend changes over time.
• Clearer experiment explanations so habit tests are easier to understand at a glance.
• Help prioritizing the most relevant insight for the day when multiple signals change at once.
• Polished share caption suggestions for social sharing.

Availability

• Apple Intelligence features appear only on compatible Apple devices where Apple Intelligence is available and supported OS versions are installed.
• Core scores, trends, and analytics still work without Apple Intelligence.
• Some advanced AI summaries, including fuller weekly narrative views, are available with Pro.

What AI does not do

• It does not replace VitalStackFit's core trend calculations or score logic.
• It does not diagnose conditions or provide medical advice.
• It does not guarantee results or predict health outcomes with certainty.

How to think about it

Apple Intelligence helps translate your existing trend data into cleaner summaries and explanations. Think of it as a supportive reading layer that can make weekly changes easier to understand, not as a replacement for the app's regular insights.

Privacy positioning

VitalStackFit presents Apple Intelligence as a privacy-conscious summarization and explanation layer. Where Apple's supported on-device or private processing applies, the experience is designed to stay aligned with those platform protections. Availability and processing behavior depend on your Apple device, settings, and supported software version.

Pro Plans

• Monthly (1 month, auto-renewing)
• Yearly (1 year, auto-renewing)

Auto-renewing subscription. Cancel anytime in Apple ID settings.

Restore purchases is available from the paywall.

VitalStackFit uses optional local reminders (weekly trend reminder).

You can enable, disable, or change reminder timing in the app.

The app may also run a best-effort background refresh to update reminder text using on-device Health data before the reminder appears.

What are the AI cards and summaries?

They are optional Apple Intelligence-powered explanations that help turn your existing trend data into shorter daily briefs, weekly summaries, clearer experiment descriptions, and polished share copy.

Why do AI summaries sometimes not appear?

They may be unavailable if your device does not support Apple Intelligence, your software version is not supported, the feature is not available in your region or language, or there is not enough recent data for a useful summary.

Does AI replace the regular insights?

No. Your regular scores, trend cards, and analytics continue to work without AI and remain the core app experience.

Do I need Pro for all AI features?

No. Some Apple Intelligence features can appear on compatible devices without Pro, while some advanced weekly AI summaries are part of Pro.

What is Persona Sharing?

Persona Sharing is a premium social feature that adds an animated branded companion to your selected VitalStackFit share mode.

Does Persona change my score?

No. Persona is decorative and reflects the same share context already shown in your selected card.

What can I export?

Depending on your selection, you can export the brag card only, the brag card with a Persona video, or the Persona video by itself.

Why does Persona export show progress?

Persona video is generated on-device at the time of export. VitalStackFit shows progress so users know when the video is being prepared.

Do I need to keep the app open during Persona export?

Yes. While Persona video is being generated, it is best to keep the app open and avoid locking the screen until export finishes.

Why is a card blank or showing “Not enough data”?

There is not enough recent data for a reliable trend view yet.

Why did my score change?

Scores reflect trend movement across multiple recent signals, not one single reading.

Do I need Apple Watch?

No. Apple Watch is optional, but it usually improves data depth and timing detail.

How do I restore Pro?

Open the paywall and tap Restore.

Why does confidence change over time?

Confidence rises as trend consistency and sample quality improve.

What is a good first week?

A good first week means 5-7 days of Health data plus daily check-ins, then reviewing your weekly trend rather than single-day spikes.

Can I share my progress?

Yes. Free users can share a quick text update, and Pro users can export Brag Cards V3 from the Social tab.

How does Daily Check-In storage work?

Only your latest self check-in for each day is stored. If you check in again the same day, it replaces the earlier one.

Is this a medical app?

No. It is a wellness trends app for informational use only.
