Back on a spreadsheet after bouncing off two apps, what does an app do that a sheet genuinely can't?

Two things, and only two things, in my experience of running both for a year in parallel.

First is latency: the app knows on Tuesday afternoon, the sheet knows on Sunday. If your failure mode is overspending mid-week, that difference is the entire product. Second is that it catches the transactions you'd never have typed, the annual renewal you forgot, the $4 charge from something you cancelled in March.

Everything else the sheet does better: your categories, your logic, your history, and nobody can deprecate it.

First tax season with two W-2s and I owed $2,400 in April

Two payrolls, two withholding calculations, and neither of them knows the other exists. That is the entire bug. The fix lives on the W-4, not in April - either the multiple-jobs section or a flat extra dollar amount per paycheck on the smaller job.

I did the flat amount route because it is easier to reason about: I picked a number, watched two paychecks, adjusted once, done. Been within a couple hundred dollars either way for three years.

Town sewer is coming down our road and the hookup quote is 18k - do we keep the septic?

Do the twenty year arithmetic before the feelings. Our version: 18k hookup, sewer charge that worked out to about 55 a month and has gone up twice since, so call it fifteen grand of charges over twenty years on top. Against that, pumping every three years, one riser and lid replacement, and a field that statistically has maybe fifteen good years left on a twelve year old system. It came out close enough that the deciding factor was that I did not want to be the one deciding, at 70, whether to spend 25k on a new field.

Steering shakes at 100 for the first ten minutes on cold mornings, then it stops

Look inside the wheel barrels before you spend a penny at a shop. Slush thrown up during the day freezes overnight into a lump of ice on the inside of the rim, and a few hundred grams stuck in one spot is more than enough to shake the wheel at speed. It melts and flings off once things warm up, which is exactly your ten minute pattern. A bucket of warm water in the driveway will confirm it in one morning.

Twelve hours a week: a second job on a payslip, or freelancing the same hours: which left you with more?

Do the arithmetic before you choose, it takes ten minutes. Take the freelance rate, multiply by hours you realistically bill rather than hours you work, then take off what you set aside for tax and anything you have to buy - software, insurance if your work needs it, an accountant. My freelance rate had to be roughly two and a half times the shift rate before the two came out level in year one. Yours may differ, but if your multiple is only two, the boring option is quietly winning.

Joint account plus two personal ones, an app that shares the joint without merging every coffee

We solved it with account selection rather than app choice. Both of us are on one subscription, but only the joint account and the two shared credit cards are linked to it. Our personal current accounts simply aren't connected, so there's nothing to hide because there's nothing there.

Each of us then runs whatever we like privately - she uses her bank's own app, I use a sheet. Two years, zero arguments about visibility. The mistake we made first was linking everything and then trying to hide categories, which every app does badly.

Buying 6 acres with no water or sewer - what did the well plus septic actually come to?

I am the cautionary tale. Bought the land assuming a conventional field because the lot looked dry, closed, then failed the perc. Heavy clay, seasonal high water table, so the design came back as an engineered mound with a pump chamber and a dosing timer. That was not a 16k septic, that was a bit over 30k, and the mound is a large permanent lump in the middle of what was going to be the lawn.

Make the perc test a condition of the sale. A soils evaluation costs a few hundred and it is the cheapest number in the whole project.

If the app is free, what is it doing with my transaction data?

Two separate parties here and it's worth keeping them apart in your head: the app, and the connection service that talks to your bank.

The connection layer has its own portal - you can log in there, see every app you've connected, and cut any of them off without touching the app itself. I do that review twice a year and I've disconnected four things I'd completely forgotten about, including a mortgage calculator from 2022.

That's the concrete action, whatever you conclude about the business model. Know where the connections live and know how to revoke them.

Is the software doing anything my paper Leitner box was not?

Three concrete things. It gives every card its own interval based on your history with that card, rather than five shared buckets, so the one you always fumble gets seen more often than its neighbours. It has no ceiling - a paper box stops at box five and the software keeps stretching cards out to months and years, which is where the real time saving lives. And it remembers cards you would have quietly stopped rotating, which is the failure mode of every paper system I have run.

Drip machine takes 11 minutes for a full carafe and the coffee comes out thin

Descale first, obviously. But if you get to the far side of two descales and it is still slow, a five year old sub-100 drip machine does not owe you anything. I replaced mine with one of the certified brewers that has to hit a temperature and contact time band to get the badge, it was several times the price, and it is the only kitchen thing I have bought that made the coffee measurably better with no change in technique.
