RenewScout is a simple subscription tracker for iPhone. Add what you're paying for, and it reminds you before you're billed — so trials don't quietly convert and forgotten subscriptions don't keep draining your account. It's also just one easy place to check when something you actually want to keep is due to renew, instead of digging through a website to find out. Free to track up to 3 subscriptions, with a one-time unlock (no subscription required) for unlimited tracking.
