PoolFish is a strongly recognized name in LP calculators: it gives users a basic tool to simulate Uniswap v3/v4 pools and estimate fee returns. But as the space matures, more sophisticated tools are needed. Metrix was built to go beyond simple calculators, combining simulation, tracking, analytics, and portfolio oversight.

In this post, we’ll compare both across major dimensions: calculator power, tracking & analytics, user experience, support for advanced strategies, and real-world usability.

Feature-by-Feature Breakdown

Here’s a concise comparison table to orient you:

Strengths of PoolFish

• Simplicity & Specialty: PoolFish does one thing well: simulate LP performance for Uniswap v3. If you just want to check a single pool’s fee potential, it’s quick and intuitive.

• Lightweight UI: No excess bells and whistles, lower barrier to entry for newer LPs.

• Position Explorer: PoolFish displays current active Uniswap positions (with filters) for public visibility.

• Pro tracking upgrade: Offers position tracking, comparison across DEXs, exports, etc. for paid users.

But these strengths become limitations for power users who need deeper insights across multiple pools, chains, or aggregated portfolios.

Why Many LPs Choose Metrix

1. Full Simulation + Real-World Tracking

Simulations can only tell part of the story. Metrix not only estimates returns before deployment, but also tracks real PnL across your portfolio, factoring fees, divergence, and external factors.

2. Analytical Visibility

You get liquidity distribution per tick, divergence charts, in-range durations, and insight into how your strategy behaves over time. These help you tweak strategies rather than purely trusting projected APR.

3. Multi-chain & Multi-DEX Integration

Your LP opportunities span chains and DEXs; Metrix supports comparing across them, not limited just to Ethereum or a few pools. This gives access to cross-chain alpha, something basic calculators often overlook.

4. v4 Support

PoolFish focuses on v3 simulation. Metrix already supports Uniswap v4 simulation and features, preparing you for the next generation of liquidity provision.

5. Workflow Efficiency

With saving, comparing, tracking, and alerts all in one interface, Metrix aims to replace entire tool stacks. Instead of hopping between dashboards, spreadsheets, and calculators, you stay in one tool.

Use Cases & Scenarios

Let’s look at two real-world scenarios where Metrix’s advantages become obvious.

Scenario A: Tracking Multiple Pools Across Chains

Suppose you run LPs on Ethereum, Optimism, Base, and maybe a Solana-convertible DEX. You want to see which pools are underperforming or draining your capital. PoolFish’s Pro tracking is limited in network support. Metrix lets you monitor all in one dashboard, spot laggards, and migrate capital easily.

Scenario B: Strategy vs HODL Comparisons Over Time

You built a v3 position in ETH/USDC at a tight range. PoolFish’s calculator shows you possible fee outcomes. But over 90 days, price drifts, did LPing beat just holding? Metrix shows realized PnL vs HODL, including divergence, so you know if the strategy was worthwhile or not.

PoolFish remains a solid calculator for LP fee estimation — especially for beginners. But as LP strategies grow in complexity (multi-chain, v4, multiple positions, full portfolio tracking), many serious DeFi users outgrow its limitations.

Metrix is built for that next stage. It isn’t just about simulating one pool — it’s about managing your entire LP portfolio with insight, control, and clarity.

👉 Try it for yourself: Run your next pool simulation on Metrix, track it live, and compare how your actual returns measure up against mere projections.
