Vestyx helps you track equity compensation, see exactly when shares vest, and understand your real tax exposure — all on your iPhone, Apple Watch, and Home Screen widgets.

Whether you have RSUs, ISOs, NSOs, or ESPP shares, Vestyx turns confusing grant letters into a clear picture of what you own, what's coming, and what you'll actually take home after taxes.

VESTING CALENDAR & DASHBOARD
See every upcoming vest date on a visual calendar. Your dashboard shows total unvested value with live stock prices, next vest countdown, and recent activity — all at a glance.

TAX PROJECTION ENGINE
Know your federal, state, and payroll tax exposure before vest day. Vestyx calculates supplemental withholding, estimates your net cash proceeds, and flags if you're under-withheld — so you're never surprised at tax time.

WITHHOLDING GAP ANALYSIS (Pro)
See the gap between what your employer withholds and what you'll actually owe. Get quarterly estimated payment amounts and a year-end tax playbook — the kind of insight that used to require a CPA.

SCENARIO MODELING (Pro)
What happens if your stock drops 30%? How does your equity look over 3 years? Run what-if scenarios to plan ahead with confidence.

AMT CALCULATOR (Pro)
If you hold ISOs, Vestyx projects your Alternative Minimum Tax exposure so you can plan exercises strategically.

YEAR-END TAX LETTER (Pro)
Generate a PDF summary of your equity income, withholdings, and tax projections — ready to hand to your accountant.

WIDGETS & APPLE WATCH
Check your next vest date and total unvested value from your Home Screen or watch face. No need to open the app.

BUILT FOR PRIVACY
All your compensation data stays on your device. No analytics. No ads. No third-party SDKs. Optional iCloud backup to your private CloudKit database — that's it.
