Dolphin users are the mid-tier spending segment in mobile games and apps. They spend more than minnows but less than whales — typically placing in the 2nd–10th percentile of your paying base by total spend.
Dolphins are often overlooked in favor of whale retention strategies — but they represent a more stable and scalable revenue base, and the highest potential for spend increase.
Who Is a Dolphin User?
A dolphin is a paying user whose total spend places them in the middle tier — above occasional small purchases but below high-value whale territory. The exact threshold varies by product.
| Segment | Position in paying base | Typical revenue contribution |
|---|---|---|
| Whale | Top 1–2% | 50–60% of IAP revenue |
| Dolphin | Top 2–10% | 20–30% of IAP revenue |
| Minnow | All other payers | 5–15% of IAP revenue |
Dolphins tend to make repeat purchases, respond well to targeted offers, and have higher retention than minnows. They're the segment most likely to move up — or down — based on product experience.

Why Dolphin Users Matter
Stable revenue base. While whales drive revenue peaks, dolphins provide consistency. A product with a healthy dolphin segment is less exposed to revenue volatility when individual high spenders churn.
Upsell potential. Dolphins have already demonstrated willingness to pay. The behavioral gap between a dolphin and a whale is smaller than the gap between a minnow and a dolphin. Targeted offers timed around engagement peaks can move dolphins up the spend curve.
Volume. There are 5–10× more dolphins than whales. Even modest increases in dolphin ARPPU — through better bundle design or offer timing — produce significant aggregate revenue impact.
How to Engage Dolphin Users
Personalized mid-tier offers. Dolphins don't respond as well to starter pack pricing as minnows, but won't spend on luxury whale-tier items either. Design offer tiers specifically for mid-range spend — bundles in the $5–$20 range with clear value.
Progression-based triggers. Dolphins tend to be engaged players. Offers triggered by progression milestones — completing a chapter, reaching a new level, unlocking a feature — convert better than time-based generic promotions.
Monitor for downgrade signals. A dolphin whose purchase frequency is declining may be moving toward minnow behavior. Catch it early with spend trend monitoring before they stop paying entirely.
Takeaways
- Dolphins are mid-tier spenders — typically top 2–10% of paying users, contributing 20–30% of IAP revenue.
- They're more numerous than whales and provide a more stable revenue base.
- Dolphins have the highest upsell potential — they've proven willingness to pay and are closest to whale-tier behavior.
- Design mid-tier offers ($5–$20) specifically for this segment — generic starter packs underperform here.
- Monitor for spend frequency decline as an early churn signal.
