HISTORICAL YIELD CURVE Compare any two published Treasury curves side by side, then drag the timeline or press play to watch a year of history move. Every curve is labeled with its shape — Normal, Flat, Inverted, or Humped — and every date pair with how it moved, from Bull Steepener to Bear Flattener. Open "Why this label?" to see the exact thresholds behind the call and the literature they come from. Dates are chosen from a calendar limited to real publication days, and an exact-values table backs up every point on the chart. HOME SCREEN & LOCK SCREEN WIDGETS Track the Treasury yield curve and 30-/15-year mortgage rates at a glance. Small, medium, large, and Lock Screen sizes — each with a clear as-of date, so you always know how fresh the data is. Widgets now refresh automatically from our rate service, and tapping any widget jumps straight to the Rates tab. A BIGGER, FASTER RATES TAB Treasury yields now sit alongside SOFR, the Effective Fed Funds Rate, and Freddie Mac mortgage averages. Explore interactive trend charts with years of history, overlay today's yield curve against one year ago, and scan 12-month sparklines on every rate row. Every rate is labeled with its true observation date and clear, self-describing change indicators, so you always know exactly what you're comparing. Rate delivery moved to a faster, more reliable service with stronger offline caching. COMPARE ANY TWO BONDS SIDE-BY-SIDE Full comparison workflows for fixed rate, callable, and MBS bonds: delta tables, comparison charts for cash flows, price sensitivity, call probability, and prepayment behavior, plus portfolio lenses (Neutral, Income, Rate Defense, Extension Defense, Option Cost) and a methodology sheet showing the assumptions behind every number. Export summaries to CSV or PDF, save comparison pairs, and reopen them later fully recalculated. SIRI, SHORTCUTS & SPOTLIGHT Ask for a Treasury yield, open today's yield curve, or look up glossary terms from Siri, Shortcuts, or system search. LEARN BOND FUNDAMENTALS Bond Fundamentals is a new guided learning track — ten short lessons building the vocabulary for reading bond prices, cash flows, and risk, with your progress saved as you go. It sits on an expanded 104-term glossary, and Learn now opens on a hub that puts your track progress, recently viewed terms, and search on one screen. Start typing to filter every definition, or browse the full glossary by category, with bookmarks and interactive concept demonstrations throughout. REDESIGNED FOR iPAD Comparison workbench layouts, menu bar commands, and keyboard shortcuts across Fixed Rate, Callable, and MBS workflows. SHARPER NUMBERS Settlement-aware bond pricing, ISDA-exact ACT/ACT day counts, and a hardened MBS yield solver. A WELCOME THAT ASKS NOTHING No account, no setup, no forms. The first run opens on today's published Treasury curve, plays the last ten years of it in a few seconds, then hands you a live bond and one control: drag the yield and watch the price move. Tap through and you land in the calculator with that same yield already loaded, ready to change anything else. Skip it whenever you like, or replay it later from Settings. Plus haptic feedback, a refreshed design language, Dynamic Type across the calculation screens — metric tables, buttons, and input fields now follow your Larger Text setting — and hundreds of quality and accessibility fixes. ### 2026.1 — 2026-01-19 Compare MBS bonds side-by-side and analyze prepayments like never before NEW: MBS BOND COMPARISON Compare two mortgage-backed securities simultaneously with fully configurable parameters. A unified rate slider shows how both bonds respond to interest rate changes, with instant delta calculations for price, yield, WAL, and duration. REDESIGNED PREPAYMENT ANALYSIS A streamlined interface brings rate shocks, horizon analysis, and scenario comparisons together in one view. Quick navigation lets you jump between sections, and smarter PSA bounds ensure realistic modeling. DELTA COMPARISON MODE New toggle between absolute and percentage changes when comparing rate shock scenarios. See exactly how metrics shift across different rate environments. ENHANCED ACCESSIBILITY Comprehensive VoiceOver support throughout the app. Every chart, table, and interactive element now provides rich descriptions, making professional bond analytics accessible to everyone.
