Sell in May
iOS Universel / Finance
Professional Market Intelligence. Completely Private.
Sell in May brings institutional-grade market analysis to your iPhone—with zero cloud dependency. Combining advanced pattern recognition with optional LSTM deep learning, it reveals what history suggests about any stock's future under similar market conditions.
Regime-Aware Analysis
Unlike basic charting apps, Sell in May understands that markets behave differently during bull runs versus bear markets. It automatically classifies current conditions (volatility, trend, sentiment) and surfaces only relevant historical patterns—giving you context-aware intelligence, not just raw data.
Dual-Engine Approach
• Pattern matching across 10+ years of similar market regimes
• Optional AI forecasting with probabilistic multi-day predictions
• Two complementary methods reduce bias and increase confidence
100% On-Device Processing
Your data never leaves your phone. No account, no cloud backend, no tracking. Just professional-grade tools with complete data sovereignty. Works offline after initial data fetch.
Professional Features
• Multi-horizon forecasting with confidence intervals
• 14+ technical indicators and risk metrics
• Optional macro-economic context (FRED integration)
• Real-time regime detection and scenario analysis
Perfect for active traders, swing traders, and privacy-conscious investors who refuse to compromise on analytical power.
No subscriptions. No surveillance. No compromise.

Quoi de neuf dans la dernière version ?
What's New:
- Watchlist Tab: A new third tab keeps all your tracked symbols in one place. Add symbols with an inline search, drag to reorder, and swipe to delete. Each row shows the company name, latest price, one-day change, and a one-month sparkline. The symbol you're analyzing and your watchlist now stay in sync — no more separate lists to manage.
- Redesigned Interface: The Analysis screen opens with a new price hero — symbol, large price, one-day change, sparkline, and a range picker for 1 week, 1 month, 3 months, 1 year, and 5 years. The Regime, Technical, Risk, and Macro cards have a cleaner look and tap through to full explanation screens that describe what each metric means, how it's calculated, and what it implies. The AI Analysis now appears as a preview card you tap to read in full or to continue in chat.
- Morning Brief & Alerts: Opt in to a daily 7:00 AM brief covering the current volatility regime, the VIX, and your active symbol's latest forecast. Regime-change and pattern-found alerts are also available, each with quick actions to open the analysis or mute a symbol for a week. A first-launch prompt explains the options; everything stays off until you allow it.
- Restructured Settings: Preferences are reorganized, with power-user controls moved into a dedicated Analysis Settings screen, a Reset to Defaults option, and a light / dark / automatic theme toggle.
- Now on Mac: The Watchlist is available on macOS too, in the sidebar.
Improved:
- Faster & Smoother: Launches and symbol switches are noticeably quicker — price and economic data are now served from a local cache first, and redundant network requests have been eliminated. Your analysis, forecast, and AI explanation now persist as you move between tabs instead of regenerating each time.
- Stability Fixes: Resolved cases where the "Analyzing" and "Generating forecast" spinners could hang indefinitely after launch, a forecast that restarted in a loop, and a crash that could occur when quitting the app.
- More Reliable Data: Improved fetching of prices and economic indicators, including better handling of rate limits and authentication so charts and the macro context fill in more consistently.
- Model Download Resume: If your selected AI model didn't finish downloading, the app now resumes it automatically on the next launch.
- Spanish Polish: Completed Spanish translations for the new Watchlist and accessibility labels and refined number/percent formatting.
