Credit where due: Planto was early to account aggregation in Hong Kong, built around the HKMA Open API era, localized in English and Chinese, and it made many people in the city see all their accounts together for the first time.
The friction users describe publicly — in app-store reviews and finance forums — is a general property of credential-based aggregation: when a bank changes its login flow, layout or step-up authentication, scraped connections can break or demand another re-login, and balances go stale until you notice. That pain is not unique to any one app; it comes with the method.
API connections work differently: access is token-based and authorized by the institution, so it tends to survive interface changes. The method varies by bank and by aggregator — including the aggregators NOVOX uses — so check how your bank connects in the demo before you commit.
For investors in Hong Kong and Singapore the difference compounds: brokerage accounts at firms like Interactive Brokers sync as real positions via SnapTrade, HKD, SGD, USD and CNY sit in one multi-currency net worth, and property and mortgages live alongside the portfolio instead of in a spreadsheet.
