Main concerns are around price tbh (I’m a cheap bastard) and I think $14 a month is steep for something I’d use loads one evening and then probably use once every quarter after that.
I think the persistent storage is the key thing to make someone want to pay and the way it’s presented feels wrong to me. If I revisit the site you basically say ‘hey I’ve got all your data stored, sign up to premium and you can have it back without entering it all’ to me that comes across a bit of a ransom. I think that’s fine I’d say a couple of days/weeks have passed. But I think if you Accidentally closed the tab or it timed out it might put people off.
I think the real money maker here is likely financial planners who can pay a large fee and share/use it with their clients over zoom or whatever. Or perhaps some kind of insights/ yearly/monthly forecast summaries for a fee.
All in all amazing job, I hope it’s a great success.
