Set up two layers and stop thinking about it. The broker's app for ground truth, an alert app for schedule changes.
- Layer one: your broker's app, your actual activity and statements - Layer two: fee alerts bundled into iOS notification summaries, a morning digest instead of interruptions - Three things worth watching: margin rate changes, account fee changes, promo deadlines - Distrust precision theater: estimates from your past activity are honest, to-the-penny forecasts are not - Run a full fee comparison once a year; alerts handle the rest
BrokerMatch ($2.99 one-time) runs that annual comparison in minutes: your activity, priced across fifty brokers.
