## Version history (last 5 releases)

### 2.0.0 — 2026-11-05

Owlvest (formerly ETF Calculator) calculates ETF savings plans, savings goals and payouts, and tracks a portfolio the user records or imports from a broker's CSV export. No account is needed; all calculations run on the device.

Premium (monthly or yearly subscription, 3-day free trial) removes all ads and unlocks portfolio import (CSV), taxes, the market fluctuation range, unlimited scenarios and color themes. Open it via any "Premium" badge in the app, tap Continue, then choose a plan. Free users see native ads and occasionally a full-screen ad; a rewarded ad lets them try Premium for one hour (up to 3 times a day).

The app asks for App Tracking Transparency permission after Google's consent form, only for personalized ads.
