RSU Tracker

Features
Read full description

Your employer withholds about 22% when your RSUs vest. Most people in tech owe 32% or more. Nobody tells you about the gap until you file. RSU Tracker shows it to you before each vest, so the bill isn't a surprise. WHAT IT DOES - See every grant, every vest date, and what each one is actually worth today - Automatic daily price updates — enter a ticker, not a spreadsheet - Vested vs unvested at a glance, across all your grants - A running timeline of what's coming and when THE TAX GAP - Set your real marginal rate alongside your employer's withholding rate - See the shortfall on every upcoming vest, in dollars - Know how much to set aside now instead of scrambling in April ESPP - Track contributions, discount, and lookback across the offering period - Lock in your purchase price when the period closes, so your share count stops moving with the market - Compare selling now against holding long enough to qualify — with the tax difference for each DECIDE BEFORE YOU SELL - Model bear, base, and bull prices on your own numbers - See after-tax proceeds, not headline value - Check how much of your net worth sits in one employer's stock PRIVATE BY DESIGN Everything stays on your device. No account, no sign-up, no sync, no tracking, no ads. Nothing to link, nothing to breach. Export to CSV or PDF when your accountant asks. FREE Two grants, full vesting timeline, current values, automatic prices, and ESPP tracking. PRO Unlimited grants, after-tax estimates and the withholding shortfall, sell scenarios, concentration risk, ESPP sale tax, vest reminders, and CSV/PDF export. Monthly $4.99 · Yearly $29.99 · Lifetime $39.99 one-time Auto-renewing subscriptions are charged to your Apple Account at confirmation and renew unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings. Lifetime is a one-time purchase, not a subscription.
