Instead of debating whether a new onboarding flow or referral incentive will work, you run an experiment and let the data decide. This article covers how to build an experimentation framework for mobile app growth, from prioritization to analysis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For A\/B testing deep links specifically, see <a href=\"https:\/\/tolinku.com\/blog\/ab-testing-deep-links-landing-pages\/\">A\/B testing deep links and landing pages<\/a>. For growth metrics to track, see <a href=\"https:\/\/tolinku.com\/blog\/app-growth-metrics\/\">app growth metrics: the 15 KPIs that matter<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Experimentation Process<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Every growth experiment follows five steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Hypothesize<\/strong>: Define what you expect to happen and why.<\/li>\n<li><strong>Prioritize<\/strong>: Score the experiment against alternatives.<\/li>\n<li><strong>Design<\/strong>: Set up the experiment with clear metrics and controls.<\/li>\n<li><strong>Execute<\/strong>: Run the test for a statistically significant period.<\/li>\n<li><strong>Analyze<\/strong>: Interpret results and decide next steps.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">The discipline is in the process, not in having brilliant ideas. Most experiments fail. The teams that grow fastest are the ones that run the most experiments per week, not the ones with the best individual ideas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Prioritization: ICE Scoring<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With limited engineering and marketing resources, you cannot test everything. The ICE framework scores each experiment on three dimensions:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Dimension<\/th>\n<th>Question<\/th>\n<th>Scale<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td><strong>Impact<\/strong><\/td>\n<td>If this works, how much will it move the target metric?<\/td>\n<td>1-10<\/td>\n<\/tr>\n<tr>\n<td><strong>Confidence<\/strong><\/td>\n<td>How confident are you that it will work? (based on data, precedent, logic)<\/td>\n<td>1-10<\/td>\n<\/tr>\n<tr>\n<td><strong>Ease<\/strong><\/td>\n<td>How easy is it to implement and run?<\/td>\n<td>1-10<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<pre><code>ICE Score = Impact \u00d7 Confidence \u00d7 Ease\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Example Backlog<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Experiment<\/th>\n<th>Impact<\/th>\n<th>Confidence<\/th>\n<th>Ease<\/th>\n<th>ICE Score<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>Simplify onboarding from 5 steps to 3<\/td>\n<td>8<\/td>\n<td>7<\/td>\n<td>6<\/td>\n<td>336<\/td>\n<\/tr>\n<tr>\n<td>Add referral bonus ($5 credit)<\/td>\n<td>7<\/td>\n<td>6<\/td>\n<td>8<\/td>\n<td>336<\/td>\n<\/tr>\n<tr>\n<td>Test new App Store screenshots<\/td>\n<td>6<\/td>\n<td>5<\/td>\n<td>9<\/td>\n<td>270<\/td>\n<\/tr>\n<tr>\n<td>Push notification at day-2 for lapsed users<\/td>\n<td>7<\/td>\n<td>6<\/td>\n<td>7<\/td>\n<td>294<\/td>\n<\/tr>\n<tr>\n<td>Add social login (Google, Apple)<\/td>\n<td>6<\/td>\n<td>8<\/td>\n<td>4<\/td>\n<td>192<\/td>\n<\/tr>\n<tr>\n<td>Redesign pricing page<\/td>\n<td>8<\/td>\n<td>4<\/td>\n<td>5<\/td>\n<td>160<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Run experiments in ICE score order. When two experiments tie, prefer the one with higher Ease (faster feedback).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Alternative: RICE Framework<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some teams prefer RICE, which adds Reach:<\/p>\n\n\n\n<pre><code>RICE Score = (Reach \u00d7 Impact \u00d7 Confidence) \/ Effort\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Where <strong>Reach<\/strong> is the number of users affected per quarter. RICE is better for teams with large user bases where some experiments only affect a segment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Designing Experiments<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Hypothesis Format<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Write hypotheses as testable statements:<\/p>\n\n\n\n<pre><code>If we [change], then [metric] will [improve\/decrease] by [amount],\nbecause [reason based on data or logic].\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Examples:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>&quot;If we reduce onboarding from 5 screens to 3, then day-1 retention will increase by 10%, because analytics show 40% of users drop off between screens 3 and 5.&quot;<\/li>\n<li>&quot;If we add a referral prompt after the first completed workout, then referral sends per user will increase by 25%, because users are most motivated after achieving a goal.&quot;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Bad hypotheses:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>&quot;Changing the button color will increase conversions.&quot; (No reasoning, no expected magnitude.)<\/li>\n<li>&quot;Users will like the new design.&quot; (Not measurable.)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Defining Success Metrics<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every experiment needs:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Component<\/th>\n<th>Purpose<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td><strong>Primary metric<\/strong><\/td>\n<td>The one metric that determines success or failure<\/td>\n<td>Day-1 retention rate<\/td>\n<\/tr>\n<tr>\n<td><strong>Secondary metrics<\/strong><\/td>\n<td>Related metrics to watch for side effects<\/td>\n<td>Day-7 retention, session length<\/td>\n<\/tr>\n<tr>\n<td><strong>Guardrail metrics<\/strong><\/td>\n<td>Metrics that must not degrade<\/td>\n<td>Revenue per user, crash rate<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If the primary metric improves but a guardrail metric degrades, the experiment is not a success.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sample Size and Duration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Running an experiment too briefly produces unreliable results. Use a <a href=\"https:\/\/www.evanmiller.org\/ab-testing\/sample-size.html\" rel=\"nofollow noopener\" target=\"_blank\">sample size calculator<\/a> to determine how many users you need:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Baseline Rate<\/th>\n<th>Minimum Detectable Effect<\/th>\n<th>Required Sample (per variant)<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>30% retention<\/td>\n<td>5% relative improvement<\/td>\n<td>~4,600 users<\/td>\n<\/tr>\n<tr>\n<td>10% conversion<\/td>\n<td>10% relative improvement<\/td>\n<td>~14,300 users<\/td>\n<\/tr>\n<tr>\n<td>2% referral rate<\/td>\n<td>20% relative improvement<\/td>\n<td>~19,000 users<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For most mobile apps, this means running experiments for 1-4 weeks. Do not stop experiments early because they &quot;look good&quot; or &quot;look bad.&quot; Wait for statistical significance (typically 95% confidence).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Growth Experiments<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Acquisition Experiments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Testing how you attract new users:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Experiment<\/th>\n<th>Metric<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>Ad creative variations<\/td>\n<td>CPI, CTR<\/td>\n<td>Test 3 different ad creatives on Meta<\/td>\n<\/tr>\n<tr>\n<td>App Store screenshot order<\/td>\n<td>Conversion rate<\/td>\n<td>Rearrange screenshot sequence<\/td>\n<\/tr>\n<tr>\n<td>Landing page copy<\/td>\n<td>Install rate<\/td>\n<td>Test benefit-focused vs feature-focused copy<\/td>\n<\/tr>\n<tr>\n<td>Channel testing<\/td>\n<td>CPI, Day-7 retention<\/td>\n<td>Allocate $500 to TikTok ads<\/td>\n<\/tr>\n<tr>\n<td>Deep link destination<\/td>\n<td>Activation rate<\/td>\n<td>Test landing on home vs specific content<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Activation Experiments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Testing how new users reach their &quot;aha moment&quot;:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Experiment<\/th>\n<th>Metric<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>Onboarding length<\/td>\n<td>Completion rate, day-1 retention<\/td>\n<td>3 steps vs 5 steps<\/td>\n<\/tr>\n<tr>\n<td>Permission request timing<\/td>\n<td>Opt-in rate<\/td>\n<td>Request push notification permission on day 1 vs day 3<\/td>\n<\/tr>\n<tr>\n<td>Tutorial format<\/td>\n<td>Activation rate<\/td>\n<td>Interactive tutorial vs video walkthrough<\/td>\n<\/tr>\n<tr>\n<td>First-run experience<\/td>\n<td>Day-1 retention<\/td>\n<td>Guided setup vs free exploration<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Retention Experiments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Testing how you keep users coming back:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Experiment<\/th>\n<th>Metric<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>Push notification timing<\/td>\n<td>Open rate, day-7 retention<\/td>\n<td>Morning vs evening notifications<\/td>\n<\/tr>\n<tr>\n<td>Re-engagement email content<\/td>\n<td>Reactivation rate<\/td>\n<td>Personalized vs generic emails<\/td>\n<\/tr>\n<tr>\n<td>Streak mechanics<\/td>\n<td>Day-30 retention<\/td>\n<td>Add daily streak counter<\/td>\n<\/tr>\n<tr>\n<td>Feature discovery<\/td>\n<td>Feature adoption rate<\/td>\n<td>Tooltip tour vs discovery prompts<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Monetization Experiments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Testing how you convert users to revenue:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Experiment<\/th>\n<th>Metric<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody><tr>\n<td>Paywall placement<\/td>\n<td>Conversion to paid<\/td>\n<td>After feature use vs on startup<\/td>\n<\/tr>\n<tr>\n<td>Pricing<\/td>\n<td>Revenue per user<\/td>\n<td>$4.99\/month vs $9.99\/month vs $49.99\/year<\/td>\n<\/tr>\n<tr>\n<td>Free trial length<\/td>\n<td>Paid conversion rate<\/td>\n<td>7-day vs 14-day trial<\/td>\n<\/tr>\n<tr>\n<td>Upgrade prompt copy<\/td>\n<td>Tap rate<\/td>\n<td>&quot;Unlock all features&quot; vs &quot;Start your free trial&quot;<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Running Experiments at Scale<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Experiment Velocity<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The most important growth metric is experiments per week.
