Native iOS stock portfolio app for the Brazilian market. Imports brokerage PDFs, computes weighted-average price, realized P&L, and the tax logic other tools skip (loss carry-forward, payment records). Multi-wallet with live pricing, category allocation, and Luiz Barsi price-floor valuation.
↗ Still in daily use as my own portfolio tool

↗ Pre-launch at chiku.live
