How early LTV forecasts change mobile app economics

Speed and Accuracy of UA Predictions

The problem every UA manager can picture: you launch an ad campaign, acquire users at $2-5 each, but only understand their real value after 7-30 days. By that time, you've already spent your budget, missed the opportunity to scale successful channels, and continued pouring money into ineffective sources.

This is the classic User Acquisition problem in mobile marketing: the gap between decision-making moment and data arrival. The earlier we understand which user will bring revenue, the faster we optimize campaigns and the more efficiently we spend budget.

Why Prediction Speed = Money

In the mobile games and apps industry, time is literally money:

• Day 1 → Day 7: every day of waiting is a day of working with "cold" data
• Budget at stake: spending $50K/day with a week's delay means $350K spent blind
• Competitive advantage: whoever optimizes bids faster gets the best traffic

The traditional approach requires waiting 7-30 days to evaluate LTV. Our approach is predicting user revenue on D4 and D7 using only first-day data. And having D7 data, we build predictions for D30 and a year ahead.

Why Day 7 Comes Too Late

Everyone on the UA team should understand this: decisions need to be made on Day 1, but the data for those decisions arrives on Day 7-30. This gap kills efficiency and eats budget.

Here's what the classic approach reality looks like:

Monday: Launched campaign with $5K/day budget Tuesday-Sunday: Looking at CPI, D1 retention, install count. Guessing whether it'll pay off Next Monday: Finally see first D7 LTV data. Campaign is unprofitable Total: $35K spent before you realized you should have stopped on day one

With accurate D1 predictions, you save $30K out of that $35K. You don't just get data faster — you get it when it can still change the outcome.

Real Cases: How Predictions Change UA Results

Case 1: Hyper-Casual Studio — From Test to Scale in 24 Hours

Problem: Tested 10-15 new creatives weekly. Classic approach required 5-7 days to evaluate D7 LTV for each creative. By the time data arrived, best creatives were losing effectiveness, and failed ones had eaten the budget.

With predictions:

• Day 1: Launch 5 creatives at $500 each
• Day 1, evening: Prediction shows creative #3 will deliver D7 LTV of $4.20 at $2.80 CPI (50% ROI)
• Day 2: Scale creative #3 to $5K/day, pause the rest

Result:

• Testing cycle: from 5-7 days to 1 day (5x speed)
• Creative win rate: +40% (found winners faster)
• ROAS: +25% (scaled before source saturation)
• Savings: $15K/month on ineffective creatives

Case 2: Midcore RPG — Hidden Potential of Tier-2 Geos

Problem: Tier-2 geos (Brazil, Mexico) showed low D1 retention and average CPI. UA team was preparing to cut budget in these regions.

Prediction showed:

• Monetization peak comes at D14-D21, not D7
• Projected D30 LTV: 18% higher than Tier-1 geos
• Reason: slower but stable engagement growth

Solution: Reallocated 30% of budget from Tier-1 to Tier-2

Result:

• ROAS grew from 110% to 145%
• Average D30 LTV increased by $2.40
• Saved on cheaper Tier-2 CPI ($1.80 vs $4.20)

Case 3: Subscription App — LAL Based on Predicted LTV

Problem: Organic retention was above average, but the team didn't understand which behavioral pattern correlated with paying subscriptions. Lookalike audiences were built on generic events → unstable CPA.

What the prediction showed: Analysis of early D0 signals identified a segment:

• Users who opened 3+ key features in first 24 hours
• Their probability of converting to paying: 3-4x higher than average
• Predicted D30 LTV: 3-4x higher than cohort average
• Important: this was visible on D1-D3

Solution: Created LAL audiences based on high-predicted-LTV segment, not generic "Install" or "Trial start" events.

Result:

• CPA of paying user decreased by 25-35%
• Conversion rate to subscription increased by 40-60%
• Campaigns shifted from near-break-even to sustainable positive ROI

Case 4: Casual Game — Scaling Without ROAS Loss

Problem: When increasing budget:

• ROAS started dropping after D7
• Team didn't understand which sources "temporarily dip" vs actually unprofitable
• Scaling happened with 2-3 week delays
• Classic D7-blindness

What changed with predictions: Instead of waiting for actual payback:

• Used predicted LTV and predicted ROAS per source
• Accounted for monetization type (Ads / IAP / Hybrid)
• Stopped sources with projected negative ROI before actual budget burn

Result:

• UA budget increased 4-6x in a quarter
• ROAS remained stable (130-145% range)
• Payback period shortened by 25-35%
• No "plateau" during scaling

What the Prediction Model Considers (and Why It Works)

The model analyzes dozens of user behavior signals already on day one: how they interact with paid features, how long they play, which levels they complete, what source they came from, what device they're on, and what country they're in.

The key is — the model is trained on millions of users from hundreds of apps across different genres. It knows that:

• In hyper-casual, a user who passed 5+ levels in first session will remain active on D7 with 78% probability
• In subscription apps, someone who opened 3+ features on D0 converts to paying 4x more often
• In midcore RPG, first purchase at level 3-5 means D30 LTV 40% higher than average

The model accounts for your product's genre, lifecycle stage, and geography — and applies the right patterns for accurate forecasting.

What exactly the model predicts:

From day one (D1) → forecast for D4 and D7:

• Overall LTV and ROAS
• Breakdown by revenue types: ads, in-app, subscriptions
• ROAS for each monetization type separately

From day seven (D7) → forecast for D30 and D90

From day thirty (D30) → forecast for D180 and D365

From day ninety (D90) → forecast for D720 (2 years)

This allows making decisions at each stage of cohort lifecycle without waiting for actual data.

Practical Application: What Changes in UA Team's Work

1. Testing Creatives and Sources

2. Bid and Budget Optimization

Result: ROAS grows 20-35% simply from proper understanding of traffic value.

3. Scaling Without Fear

4. Working with New Sources and Geos
