MarketMatch is an iPhone app. It is in TestFlight beta right now and headed to the App Store. Subscribers get the TestFlight invite by email within a day of subscribing; reply to that email if it does not arrive.
There are no passwords. Enter the email you subscribed with, we send a 6-digit code, and you are in. Codes expire after 15 minutes. If the code never arrives, check spam, then request a new one.
Subscriptions are billed by Stripe. Change plan, update your card or cancel from your account page under Manage billing. Cancelling keeps your access until the end of the paid period.
