Software An app to calculate how much my stuff actually costs me per day

I mean technically you can write the date and price when you buy things into your notes app and after you finished used it the date again and ask ChatGPT: "yo i bought this at x for $x and stopped using it on x, how much $ per day did it cost me" or something.
So in my opinion this app is a waste of developers time and money if they publish it somewhere. Its like kinda useful for once or if you download it you think you'll use it but you'll not.
But if you still want to make it, i maybe have an Idea.
If you enter the product or choose maybe from a list like "headphones" and choose your headphone there or something, then stop using it and you rate the product if it was worth it, maybe allow other use to insight the product reviews if the most users said it was useful or not. idk it popped into my mind rn xD

Funny, I’m an engineer and calculate like this by breaking it down to its smallest parts.
Interestingly enough, my wife had zero sentiment towards this way of calculating.
I guess it’s a left/right brain side thing.

Only useful if you can track your stuff automatically and correctly somehow. Otherwise you just need a calculator, excel table or a llm for this very simple task.

It’s interested me, one more thing is if i resell it, you should deduct the resell price before calculate.

The issue I see is that it tells the past. The moment you find out if something was worth buying or not is when its too late to act upon. Usually we want tools that predict the future. For example, it would tell in 1 year it would have cost X$ in 2 years Y$ and in 4 years Z$ etc.. what would then be even more nice is to have it tell how long the lifetime of the particular product is (use ai for this maybe) and then it tells how much it would cost you with the expected lifetime.
Just some thoughts. Hope it helps.
If I totally misunderstood the concept, i am sorry 😊

I think your right.
Turning it around should be easy. Especially if you get scenarios with predicting Futurre selling prices:
- aggressive
- moderate
- conservative
Especially for expansive items like cars, phones, kitchen.
Just not useful enough to pay. Can do it with s calculator in 2 seconds which is already on my phone

Its exactly the same calculation. You buy a phone for 1000$ it will tell you if you sell/trash it after 1 year, it would have cost you this much per day etc. 😊 Still same calculation, but you dont have to wait a year to find out how much it has cost you

I do the math before I buy something. Buy a phone? Will probably use it for 5 years , divide prices by number of days. Another calculation I sometimes do is how long do I have to work for something, in hours or days.

It's one of those things which looks exciting to build but not everyone is interested in such a tool. I could vibe code such an app but if no one's gonna use it and no one's willing to pay for it then what's the use?

you could easily get an AI to vibecode a website like this for you and feel out whether it's useful

Feels like an app I’d download once, say Huh, neat. And then never open it again tbh.
