This is absolutely awesome. I really appreciate how snappy it feels. I wouldn't mind if it was supported by something like (tasteful) personal capital or credit card affiliate links.

Otherwise, it's too expensive for cheap fire-minded folks like myself. Adding a subscription to this would push back our FIRE dates :)

Persistent storage (even if it's just a text file I have to copy-paste every time) for $12/ a year would add enough value to be worth it for me, and for me to replace my spreadsheet with this.



Glad you appreciate the snappiness :) that's the product of a lot of deliberation on optimizations and occasional shower thought / moment of inspiration. Maybe what I should do is add another tier that's just persistent storage with none of the other premium features; essentially "Basic" but with saving.


I would appreciate, no doubt.

I think I have a mental friction on paying monthly based on how much I interact with the software, so it might be me.


There's always the yearly/lifetime options if monthly gives you pause. Would you suggest adding a lower tier lifetime option with just saving?


I missed the lifetime option, that's good!

I'm not sure how I feel about the persisting being a premium feature yet, I have to play with the software a bit more. It might be that a tier in-between with just persisting would solve the problem, but it could just be that I haven't realized the software' s full potential.

You get a lot of points for making it work well with the phone, I was really surprised.


That was indeed nontrivial haha. Did you try running it as a PWA? I've noticed there's a bit of weirdness in mobile browsers where content shifts/clips when you scroll sometimes; haven't dug into what's going on there yet, but that seems to go away when running as a PWA.


I installed the PWA but was still using the browser. Will give it a try.

What made it surprising is that usually diagrams and tables display horribly on phone in most apps. This app is centered around those and works well, which is literally amazing.


Thanks; glad you like it! I think there's still some room for improvement in the mobile version. To me it definitely doesn't feel like a "mobile first" experience... but it is serviceable at least.


hi! I've been using your software more actively, what's the best way to provide feedback? I thought you could appreciate input on things as a "pair of fresh eyes"


Definitely! Discord/email are easiest (links in app)


This is not the answer about the PWA, but WOW, thank you.

I put in some serious numbers and it looks great. Now I'm a bit concerned for the last 3 years of my life, lol

I will definitely want the "tax adjustment" feature, I'm very happy you provided the "lifetime" option.

Do you have a "plan" in case everything goes wrong and you don't have enough funds? I wouldn't want to lose all the planning. That being said, the software is incredibly good, I don't expect that to be a thing.


One of the nice things about being a solo dev building this as a side project is that I don't have investors I need to pay back, and so far operating costs are pretty minimal :)


agreed, I'd love a txt/csv dump of my plans
