30 Day Retention Tracking for Indie Apps
30-day retention tracking measures how many users return to your indie app after 7, 14, and 30 days of first install. Attribr provides real-time cohort analysis so you can identify which user segments stay engaged and which drop off.
What Is 30-Day Retention and Why It Matters
30-day retention is a critical metric for indie app developers because it reveals whether users find genuine value in your product. Unlike download counts, retention shows actual user behaviour. A user who installs your app but never opens it again costs you acquisition spend without generating revenue or engagement. Attribr tracks this automatically across iOS and Android, breaking retention down by cohort, feature, and user segment. This lets you understand not just how many users stay, but why. A healthy indie app typically sees 20 - 40% retention by day 30, though this varies by category and use case.
How Attribr Tracks 30-Day Retention
Attribr uses server-side event tracking to measure retention without reliance on IDFA or Google Advertising ID. You send user events (app opens, feature usage, purchases) to Attribr's API, and it automatically builds cohorts based on install date and user properties. The dashboard shows retention curves, day-by-day drop-off, and comparison views so you can spot trends early. You can segment retention by acquisition source, user property, feature adoption, or in-app behaviour - crucial for indie developers who need to optimise limited marketing budgets. Retention data updates daily, so you see patterns in real time.
Using Retention Data to Reduce Churn
High churn in the first 7 days usually signals onboarding problems; churn after day 14 often reflects feature depth or engagement loops. Attribr lets you cross-reference retention with feature events and custom properties, so you can test whether users who engage with feature X stay longer than those who don't. This insight drives product decisions: should you redesign onboarding, add notifications, or push a specific feature? For indie teams without large user research budgets, retention cohorts become your north star. Pairing retention analysis with session replay or heatmap tools strengthens the story further.
Retention Benchmarks for Different App Categories
Retention benchmarks vary significantly by type. Utility apps (weather, notes, calculators) often see low retention because users install them once and stop returning until they need them. Social and gaming apps expect higher day-30 retention (30 - 50%+) because engagement is built into the product loop. Productivity apps sit in the middle. Attribr's dashboard lets you compare your app's retention against peers in your category, so you know whether a 25% day-30 rate is acceptable or alarming. Understanding these benchmarks helps indie developers set realistic goals and prioritise improvements.
Integration and Data Privacy
Attribr integrates via a simple REST API or mobile SDKs for iOS and Android. You decide which events to track - there's no magic required, just forward the data you care about. Attribr doesn't rely on fingerprinting or invasive ID matching; it uses deterministic server-side cohorts built on your own event stream. This keeps user data private and compliant with privacy regulations. Setup takes hours, not weeks, and pricing scales with event volume so indie developers only pay for what they use. The free tier is generous enough for early-stage apps to validate the product before scaling.
Going Deeper: Retention Beyond Day 30
While 30-day retention is your primary checkpoint, Attribr tracks retention at any interval - 7 days, 14 days, 60 days, 90 days. Some indie apps benefit from measuring weekly stickiness (users active at least once per week) rather than simple day-30 return. You can also segment retention by user value: do users who make an in-app purchase stay longer? Do users referred by your existing community retain better than paid acquisition? These questions are answered in Attribr's retention module. Armed with this insight, you refine both product and marketing strategy.

Frequently asked questions
What's the difference between day-1, day-7, and day-30 retention?
Day-1 retention shows users active the next day after install (tests immediate value). Day-7 retention shows users active again after one week (tests habit formation). Day-30 retention shows users active again after 30 days (tests long-term stickiness). Attribr tracks all three simultaneously so you see the full retention curve.
How do I improve 30-day retention for my indie app?
Identify which user cohorts or features correlate with higher retention using Attribr, then redesign onboarding around those patterns. Focus on reducing friction in the first 7 days, adding value by day 14, and building habit loops by day 30. Test incrementally and measure the impact on retention cohorts.
Does Attribr require an SDK or third-party tools?
Attribr provides SDKs for iOS and Android, but retention tracking works via API too - send events from your backend. You can also integrate with mobile analytics tools or forward events from platforms you already use.
What if my indie app has zero retention data yet?
Attribr starts tracking from the moment you implement it, so retention cohorts build automatically going forward. You won't have historical data, but you'll begin seeing 7-day and 30-day trends within weeks of launch.
Can I track retention for different user segments separately?
Yes. Attribr supports cohort segmentation by acquisition source, user property (e.g., paid vs. free tier), feature adoption, or custom event data. This lets you compare retention across user types and refine your strategy per segment.
