Steadwell is a record of your house. How old the roof is. When the water heater went in. What paint is on the guest bedroom trim, and which breaker the dishwasher is on. The things you would otherwise guess at, dig through a drawer for, or ask the person who lived here before you. It also says when something is worth looking at — the furnace filter, the gutters, the smoke alarms — and it says it quietly. There is no red, no "overdue", and no running count of what you haven't done. Steadwell keeps a record. It doesn't keep score. APPROXIMATE ANSWERS ARE FINE "Some time in 2019" is a real answer, and so is "before my time". Nothing here asks you for a date you don't have, and nothing looks half-finished because you didn't have one. IT ALREADY KNOWS WHAT MOST THINGS NEED Sixty-odd maintenance suggestions, each with what the manual says, what most people do, and usually something more forgiving — you pick, and you can ignore all three. A tankless water heater is never offered an anode rod it hasn't got. IT ALL LIVES ON YOUR PHONE No account, no sign-in, no server, and it works with no signal at all. If you want your own devices in step, sync runs on your own iCloud and is off until you switch it on. You can share one house with the person you live with. YOURS TO TAKE WITH YOU One backup file that puts everything back exactly as it was. Or a set of spreadsheets, if you would rather keep it somewhere nothing can lock it away. Free. No ads, no subscription, no in-app purchases, and nothing watching what you do.

Verdict
The clearest difference is rating: Steadwell at 4.7 against Sutro's 3.9. Steadwell also leads on update cadence (every 5 days vs every 2 months). Sutro's advantage is ratings volume (175 vs 3) and iOS requirement (12.4 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
