Comparison
A SumOne alternative for couples
SumOne is a daily question app with a pet attached, and the pet is not a gimmick. Each day, at a time you choose, both of you get the same question. Answering it helps your shared EggMon grow and hatch, and earns pebbles, an in-app currency you spend on decorating its room. It sounds slight and it works: the listing claims six million users.

The pet gives a daily question something most question apps lack, which is a reason to come back that has nothing to do with self-improvement. If the two of you would enjoy raising a small creature together, SumOne is the app to use and HeartTap has nothing that replaces it.
HeartTap has no pet and no decorating. It puts its effort into a status widget that shows your partner’s photo, video or drawing on your home screen, a live canvas you both draw on, a question library you choose from in place of one daily question, and a three-prompt check-in. Which you want depends on whether a shared pet or a shared window sounds more like the two of you.

Competing apps change quickly. This describes each app’s core positioning as of October 2026, and the feature the comparison turns on rather than an exhaustive audit. Check the current store listing before deciding.
Pick SumOne if
- Raising a pet together is the appeal, because nothing in HeartTap replaces it.
- You want exactly one question a day, delivered at a set time, with no choosing.
- You like decorating and collecting as a reason to keep coming back.
Pick HeartTap if

- Drawing together live sounds better than decorating a room.
A note on how this is written
We make HeartTap, so this is not a neutral review and you should not read it as one. What we have tried to do instead is be specific about what SumOne is genuinely better at, since a comparison page that concludes the author’s own product wins on every row is not telling you anything. If you want the wider view, the best couple widget apps page covers the category, and cross-platform support is worth checking for whichever app you pick.

Questions for couples
Over 2000 questions, with both answers hidden until you have each replied.
Frequently asked questions
What is SumOne?
A couples app built around one question a day. Both partners answer, and answering feeds a shared virtual pet called EggMon and earns currency for decorating its room. It also has memo and anniversary widgets and a mood tracker.
Does HeartTap have a pet like SumOne?
No. If the pet is what you want, SumOne is the better choice. HeartTap’s reason to come back is the widget itself, which changes whenever your partner posts, plus a streak and a level the two of you build together.
How do the questions differ?
SumOne gives you both the same single question each day. HeartTap has a library of over 2000 sorted into categories, and you pick the one that suits the moment, with the option to keep both answers hidden until you have each replied. One is a ritual and the other is a shelf.
Can we use both?
Yes. They do different jobs: SumOne is a daily ritual with a pet, and HeartTap is a widget with things to do around it. Plenty of couples run a question app and a widget app side by side.
