Muster Pro
Pro is an auto-renewing subscription sold monthly or yearly. The price and the billing period are on the paywall, in your currency, before you buy. It renews until you cancel.
To cancel: iPhone Settings › your name › Subscriptions › Muster. Cancelling keeps Pro until the end of the period you already paid for.
Refunds go through Apple, not us, at reportaproblem.apple.com.
I paid and the app still says free
Tap Restore Purchase on the paywall or in Settings. It works without an account. If it still says free, check that the device is signed in to the same Apple ID that bought the subscription, then write to us.
An asset I want is missing
Muster runs on a curated list of US stocks, ETFs and major coins, not on everything that trades. A ticker needs enough daily history to backtest fifty strategies over three horizons, so thin and recently listed names stay out. Send us the ticker and we will look at adding it.
A verdict says INSUFFICIENT
That is the app working. Fewer than five strategies beat holding that asset on that horizon, so there is no count worth reporting. Settings › Method explains the qualifying tests and lists every strategy.
Alerts are not arriving
Alerts are a Pro feature and fire when a horizon changes its verdict, which on a long horizon can be weeks apart. Check that notifications are on in iPhone Settings › Muster, and that the horizon you want is enabled in the app's Settings.
Deleting your data
Settings › Delete local data clears the watchlist, the cached counts, and the anonymous identifier the list is stored against. After that nobody can reach the old list, us included. To have the server rows removed outright, email the address above.
