Thank you Simon for inviting me to post here.
Beanie Budgets is a beancount compatibile native iOS app. I have been working on it for purely personal reasons: I really wanted an elegant iOS app to capture transactions on the go. More to the point, I didn't want to pay for subscriptions or entrust my data to someone else's server.
Which explains my plans for pricing. I intend to offer Beanie Budgets as a core version completely free. The free version should be enough for most people and provides a fully featured ledger, or compatibility with your own beancount ledger (hopefully anyway pls let me know!). It also includes budget setting, a series of reports and useful quality of life tools baked-in to detect, create and edit recurring transactions; make and allocate balance adjustments; calculate and allocate interest on mortgages and loans correctly; and auto-clear credit cards.
I do intend to charge a one-off "Pro" version unlock to people willing to pay for a few extra bells and whistles (multi ledger support, financial planning reports based on your actual ledger data, customised budgets, theme customisation etc.). I was thinking of £10 or so...? I can see a lot of potential to develop the financial planning reports further. There's a big benefit to ground these in real ledger numbers and real saving patterns. Working versions of these reports are live now in the app but they need a bit more polish, just turn on "Pro" features in Settings.
It's a closed source project at least for now. Requires iOS 18 or above.
I have a few places left on TestFlight. Looking forward to your feedback 
PS I know the website needs a lot of work, I'll get round to it
