Облигатор is a precise bond yield calculator and portfolio tracker powered by live Moscow Exchange (MOEX) market data. If you hold bonds in a brokerage account and want to know your real yield to maturity, track coupon payments, and evaluate put/call offers, Облигатор does the math quickly and without extra steps. CALCULATIONS YOU CAN TRUST The app computes yield to maturity (YTM), current yield, and duration. Amortization, offers, and accrued coupon income (ACI/НКД) are handled correctly. No shortcuts, just proven financial formulas. MULTI-ACCOUNT PORTFOLIO Track holdings across multiple brokerage accounts and view consolidated analytics by issuer, maturity, and yield. All data is stored locally on your device, with no sign-up and no sharing with third parties. CATALOG AND MOEX DATA The bond catalog is built from public Moscow Exchange (MOEX) data. Filter issues by type, issuer, maturity, and yield to find the right bonds in a few taps, right inside the app. PAYMENT CALENDAR AND REMINDERS The coupon and maturity calendar shows upcoming payments for your holdings. Local notifications remind you about coupons, offers, and maturity dates, so important events never slip by. WHAT-IF CALCULATOR Explore scenarios: how does your yield change at a different entry price or holding period? The target yield calculator shows the purchase price needed to reach your goal. Облигатор is a calculation tool, not a source of investment advice. Every figure helps you make your own informed decisions. Download Облигатор and analyze bonds the way a serious investor should. ## Version history (last 4 releases) ### 1.2.1 — 2026-08-19 Fixes and optimizations. • The More tab has been rebuilt: every tool opens on tap again, with search and topic grouping — Analysis, Portfolio, Market, App. • Added the missing tools: accounts, catalog, price refresh, amortization, yield, offers, opportunities and notifications. • Fixed navigation in Favorites and Compare — the Back button works again and neither screen is a dead end. • Resolved freezes when switching tabs or tapping the active tab repeatedly. • Faster screens for large portfolios: fewer redundant recalculations and smoother scrolling. • The keyboard now dismisses on every screen with calculation fields. • Optimized memory usage and secure storage access. ### 1.2.0 — 2026-08-18 A major update — the app has changed both inside and out. • Fully redesigned interface and new navigation: five sections plus an "All tools" screen • Market pulse on the home screen: currency rates and portfolio change • Investment center: portfolio signals, bond attractiveness scoring, interest-rate scenarios, yield curve and a reinvestment plan • Strategy lab: maturity ladder, rebalancing, allocation optimizer and explainable recommendations • Market metrics: volatility, Value at Risk, maximum drawdown and liquidity scoring • Transaction import from CSV and XLSX files with preview • FIFO tax result and rating event history • App lock with PIN, Face ID or Touch ID • Onboarding guide for beginners • Fixed freezes when switching sections and sped up calculations ### 1.1.0 — 2026-07-28 Bug fixes and stability improvements.
