Stage 7 of 7 — PM Lifecycle

Measure & Iterate

I’ve built Snug Tonight — but how will I know if it’s actually working? This stage is about planning how I’ll listen to what parents tell me (and what they don’t), track the numbers that matter, and figure out what to build next.

7.1 Measurement Philosophy

How I Know If It’s Working

The morning feedback — those stars, the outfit rating, the wake-ups — that’s my most important data. It tells me the one thing I need to know: did baby sleep well? If a parent tells me “too warm” three nights in a row, I know my recommendation engine needs work for that temperature range.

But morning feedback alone doesn’t tell me everything. I also need to watch what parents actually do in the app, listen to what they say in WhatsApp messages, and figure out where I’m losing them. Those three things together give me the full picture.

My rule: If I can’t explain why I’m tracking something in one sentence, I don’t track it. Download numbers and page views are noise. Whether parents come back tomorrow night — that’s signal.

📊 Quantitative — What They Do

How often do parents open the app? Do they come back? Which features do they use? This tells me what is happening.

💬 Qualitative — What They Say

Morning feedback, WhatsApp conversations with beta parents, and honest reviews. This tells me why things are happening.

🔍 Observational — What They Don't Do

Where do parents stop? Which features do they ignore? Where do they leave the app? This tells me where I’m losing them.

🔄 Experimental — What I Test

Small tests — like changing the onboarding flow or tweaking TOG recommendations. This tells me what to change to make it better.

7.2 Analytics Implementation Plan

What I Track and Why

I've mapped out every event I plan to track to a question I need answered. I'm keeping it simple — something I can set up in a weekend — but complete enough to help me make real decisions about what to fix and what to build next.

What I Track

I've designed an event taxonomy that maps every tracked action to a specific product question. Events are prioritised into three tiers: P0 (critical for understanding retention and recommendation accuracy), P1 (important for feature adoption), and P2 (nice-to-have for personalisation insights). The taxonomy covers the complete user journey from onboarding through daily use.

Analytics Implementation

Snug Tonight tracks events through: (1) in-app morning feedback stored per-child (built-in to the app), (2) event logging for key user actions across the complete user journey, (3) retention and session tracking via privacy-friendly analytics. Events are tracked at each critical conversion point to identify where users drop off and why.

Privacy note: Snug Tonight handles data about children. Signed-in users sync data via Supabase (encrypted, server-side), while free users keep data on-device only. My analytics approach is privacy-first from day one — cookieless, GDPR/POPIA-compliant tools. No personally identifiable data is sent to analytics providers. South Africa's Protection of Personal Information Act (POPIA) applies.
7.3 Key Metrics Framework

The Snug Tonight Metrics Hierarchy

Not every number matters equally. Here’s how I think about my metrics — starting with the one number I care about most (do parents come back after 7 nights?) all the way down to feature-level details.

Primary Metric
D7 Retention
Target: ≥ 40%
Recommendation Accuracy
85%
Outfit feedback "Just right"
Growth
1,000
MAU by Month 3

Metrics Hierarchy

LevelMetricTargetWhy It Matters
Primary Metric D7 Retention ≥ 40% If parents return 7 nights in a row, I've created a habit. This is the single best predictor of long-term product success.
Health Outfit "Just Right" rate ≥ 85% Measures recommendation accuracy from morning feedback. If this drops below 70%, the core promise is broken.
Health Feedback submission rate ≥ 60% % of users who check the morning feedback. A low rate means the loop isn't working.
Engagement Evening sessions per week ≥ 5 Active users should open the app most evenings. Measures habit strength.
Engagement Multi-baby adoption ≥ 20% % of parents who add a second baby. High adoption = higher switching cost and retention.
Engagement Wardrobe items per user ≥ 3 Parents who build a wardrobe are invested. This is the strongest retention predictor after D7.
Growth Organic share rate ≥ 10% % of users who share the link. Word-of-mouth is my primary growth channel.
Growth Onboarding completion ≥ 80% % who finish onboarding (name + baby). Drop-off here = friction problem.
7.4 User Feedback Loops

Three Feedback Channels

I’m planning three ways to hear from parents — each will tell me something different. The morning feedback is instant and daily. WhatsApp conversations go deeper. And watching what parents don’t do (the features they ignore, the screens they leave) will tell me what I’m missing.

Loop 1: In-App Morning Feedback (Real-Time)

Evening
Get recommendation
Night
Baby sleeps
Morning
🥵 ✅ 🥶
Pattern
7-night insight
AspectDetail
CadenceDaily — every morning after baby wakes
InputSleep quality (1–5 stars), outfit feedback (Too cold / Just right / Too warm), night wake-ups counter, optional notes
Output7-night history grid, sleep quality trends, "just right" ratio, pattern insights (avg rating, % just right, avg wake-ups, pattern detection like "baby runs warm")
Data useValidates recommendation accuracy. Feeds personalised tips. Detects patterns in sleep quality and wake-ups. Signals when to adjust recommendations.

Loop 2: Qualitative Feedback from Beta Users

AspectDetail
CadenceWeekly during Phase 1, monthly during Phase 2
MethodDirect WhatsApp messages and conversations with beta parents
Key questions"Was the recommendation accurate last night?" / "Would you share this with a friend?" / "What's the one thing that would make this better?"
Data useUncovers emotional drivers, trust barriers, and feature requests that analytics can't reveal.
7.5 Conversion Funnel

From Visitor to Daily User

Here’s the journey I expect parents to take — from finding the app to becoming someone who uses it every night. At each step, some parents drop off. My job is to figure out where and why.

The make-or-break moment: Did the parent come back the next night? If someone sees a recommendation and never opens the app again, I’ve failed. Everything I build in V2 should aim to get parents to come back tomorrow.
7.6 Post-Launch Review Template

What Went Well, What Didn't, What's Next

Two to four weeks after launch, I’ll sit down and ask: what actually happened? This will be the most honest document I write — because it forces me to look at what I got wrong, not just what went well.

CategoryQuestions to Answer
🟢 What went well Which features got the most positive feedback? What exceeded my targets? What were users surprised and delighted by? What did I ship faster than expected?
🟡 What could improve Where did users get confused? Which metrics are below target? What did users ask for that I don't have? Where was the biggest funnel drop-off?
🔴 What went wrong Were there critical bugs? Did any recommendations cause harm (overheating/cold)? Did I miss a major user need? Any technical failures?
📊 Data summary D1 retention: __%. D7 retention: __%. "Just right" rate: __%. Onboarding completion: __%. Top 3 user requests: 1) ___ 2) ___ 3) ___
💡 Key insights What surprised me? What did I believe pre-launch that turned out to be wrong? What user behaviour was unexpected?
➡️ Action items Top 3 changes for V1.5. Top 3 features for V2. One thing to stop doing. One thing to start doing.
The best learning always comes from surprises. If every number matches what I predicted, I’m either lucky or I’m not measuring the right things. What I’m really looking for is the gap between what I assumed would happen and what actually happened. That gap tells me what to build next.
7.7 V2 Roadmap

7.8 Experiment Ideas

Things I Want to Test

I've identified several experiments to run once I have enough post-launch data. Each one starts with a hypothesis and has a clear success metric. Here are the areas I plan to test:

Onboarding Optimisation
Conversion

Testing different onboarding flows to maximise completion rate without hurting engagement quality. Measuring onboarding completion and D7 retention.

Feedback Loop Engagement
Engagement

Testing when and how to prompt for morning feedback to increase the submission rate — the feedback loop is critical to improving recommendation accuracy.

Feature Adoption
Adoption

Testing prompts that encourage wardrobe and share feature adoption, since engaged users with invested wardrobes show significantly higher retention.

Trust & Credibility
Trust

Testing whether adding guideline attribution to recommendations increases parent trust and long-term retention.

7.9 The Iteration Mindset

Why This Never Really Ends

This isn’t a project that ends when I ship V1. Every morning feedback entry, every pattern I spot, every feature request — it all loops back to the beginning. The product gets better because I keep listening.

How V1 Data Will Feed into V2 Discovery

Example scenarios — these are the types of insights I expect post-launch data to reveal:

Potential V1 LearningV2 Discovery Question
Morning feedback shows 20% "too hot" in Durban Are my TOG mappings calibrated for coastal humidity, or just inland dry heat?
70% of parents use city search, only 30% use geolocation Should I default to city search instead of asking for location permissions?
Multi-baby parents retain at 2× the rate of single-baby parents Should I target multi-child families more aggressively in my marketing?
Wardrobe users submit 3× more morning feedback Is the wardrobe driving engagement, or are engaged users more likely to use the wardrobe? (Correlation vs. causation)
NPS comments repeatedly mention "I wish it told me what to buy" Is shopping integration a retention feature or a growth feature? How should I position it?
This is what makes Snug Tonight more than a side project. I didn’t just design it — I built it, planned the launch, and mapped out exactly how I’ll measure what happens and use the data to plan what’s next. That’s the full PM lifecycle, and it’s what I want to show.
