## Stock Analysis

**Free-first stock and ETF research site covering 119 exchanges; Pro adds full history, saved screens and exports.**

**Best for:** Investors who want fast, clean fundamental data and a capable screener without paying — including outside the US.

Strengths:
- One of the most usable free tiers in the category: screener, country selection, watchlists and alerts at $0
- Genuine global reach: 119 exchanges listed with per-exchange stock counts
- Cheap Pro tier ($79 per year) and a public changelog shipping features almost weekly
- Best-rated mobile apps in this category (4.9★ on both stores)

Trade-offs:
- The vendor's own docs admit non-US stocks carry fewer data points
- Export is licensing-constrained (fallback provider, some columns unavailable) and capped at one download per day on Pro
- No API at all, and displayed history caps at 20 years
- No custom formulas — screener filters are preset fields with thresholds

## Zacks

**US research service built around the Zacks Rank; genuine free tier, a large preset-screen library and a 125-field custom screener.**

**Best for:** US-focused investors who want an opinionated, estimate-driven rating system with a usable free tier — not a technical scanning workstation.

Strengths:
- Zacks Rank has run continuously since 1988 on a documented estimate-revision method — and covers mutual funds and ETFs too
- Deep genuinely free tier: rank and Style Scores, portfolio tracker with daily email alerts, basic screens
- Large curated library: 45+ premium screens in 9 strategy categories plus 39 thematic screens
- Unmatched earnings-estimate depth: revisions, surprises and the Earnings ESP filter

Trade-offs:
- Screens US exchanges only — no foreign exchange is searchable, international exposure is ADRs
- Technical criteria are minimal: price action and volume, no RSI or moving averages
- Custom formulas and backtesting require Research Wizard, sold separately on top of Premium — and renewal prices of the higher bundles are not public
