Duetto is a budgeting app built for couples. Both partners get equal access to one shared budget, so nobody's managing everything while the other's left guessing.
It also tracks home maintenance alongside your spending. HVAC servicing, air filters, water heater checks. The expenses that blindside couples financially almost always started as small tasks that got forgotten.
The result is simple: you stop reacting to what already happened and start knowing what's coming. No bank logins, no data selling.
You're at the store and your partner texts asking if you can buy a new couch. Instead of guessing, you both open Duetto and know exactly where you stand.
Your HVAC hasn't been serviced in two years. You didn't realize it until it stopped working in July. Duetto reminds you before that happens.
One partner has been tracking everything, the other has no idea what was spent. With Duetto, both of you see the same picture in real time, no catching up needed.
The water heater was making noise for months. Nobody logged it, nobody scheduled a checkup. Duetto keeps a maintenance history so nothing quietly becomes an emergency.

My wife and I tried every budgeting app out there. They all had the same problem: one of us ended up managing everything while the other felt monitored. That's not a budgeting problem, that's a design problem. So I built Duetto. One shared budget, equal access, no hierarchy. And since we own a home, I added maintenance tracking too because that's where our surprise expenses actually came from. Forgotten filter changes, overdue HVAC service. Small stuff that gets expensive fast. We're currently in beta, works on web and mobile right now with iOS and Android apps coming soon. Early beta users get lifetime premium access, no strings attached. If that's you, would love to hear what you think.
Combining budgeting with home maintenance tracking is a genuinely original angle — the insight that surprise expenses usually start as forgotten maintenance tasks is spot on. Most budgeting apps treat spending as the problem when the real issue is visibility into what's coming. The equal-access design for couples also solves the common dynamic where one partner becomes the "money person" by default. Manual entry only (no bank logins) is a trust advantage worth emphasizing more prominently.

The visibility angle is something we learned from our own experience before building Duetto. We'd track spending fine but still get blindsided because we had no view of what was coming up at home. And yeah, you're right about the manual entry point, we definitely undersell it. It's a deliberate choice, not a limitation, but we don't always frame it that way. Appreciate the nudge!

This is a really thoughtful take on budgeting for couples. Most apps focus on tracking past spending, but tying it to home maintenance and future expenses is a smart shift — that’s where a lot of “unexpected” costs actually come from. The equal-access model also makes a lot of sense. It feels less like one person managing and more like shared awareness, which is probably the real goal.

This is exactly the insight we kept coming back to while building it. Those 'unexpected' costs are almost never actually unexpected, they were just invisible. Shared awareness is honestly the perfect way to describe what we were going for. Thanks for getting it so clearly!

The shared budget approach is really interesting. Most budgeting apps treat finances as a solo activity, but for couples that creates an imbalance where one person ends up being the "money manager" by default. Having equal access from day one changes that dynamic completely. The home maintenance tracking is a clever addition too. Those forgotten tasks (filters, HVAC checks) are exactly the kind of expenses that feel "unexpected" but are actually predictable if you track them. Smart to bundle that with budgeting rather than treating it as a separate tool.
