Listub

No description of Project Euler yet.

Listub replaces the pile of single-purpose apps most households run on. Instead of one app for the shopping list, another for tasks and a third for splitting the dinner bill, everything lives in one place - and every list can be shared with the people you share your life with. What's inside:...

Questions & Answers

As answered by people managing Project Euler and Listub.

What makes your product unique?

Listub's answer:

Most organizing apps do one thing. Listub does seventeen - shopping lists, tasks, notes, documents, meal plans, travel, subscriptions, shared expenses, health schedules, plus movie and book trackers - and they all share the same rooms, the same sharing model and the same AI assistant. Add something in one module and it lives alongside everything else, instead of in its own silo on its own tab of its own app.

Why should a person choose your product over its competitors?

Listub's answer:

Because the alternative is five subscriptions and five apps that don't talk to each other. Listub covers what Todoist, AnyList, Splitwise, TripIt, Goodreads and a subscription tracker each do separately, in one app that works on web, iOS, Android, macOS, Windows and Linux, offline, in 41 languages. Every module is free to use, and Lumi - the built-in AI - handles the actual work in plain language, so you're not filling in forms.

How would you describe the primary audience of your product?

Listub's answer:

Households: families, couples and roommates who already coordinate over messages and sticky notes, and want one shared place instead. It's equally useful solo for anyone tired of running a separate app for every kind of list. The 41-language support makes it a natural fit outside English-speaking markets, particularly across Europe.

What's the story behind your product?

Listub's answer:

Listub started in 2020 with a frustration most people share: juggling a separate app for tasks, another for notes, another for shopping, another for planning - none of which talked to each other. Founder Clirim Uskana set out to build one place where all of it could live together. Development began in 2022 with a small distributed team spanning full-stack, mobile, design, QA and DevOps, and over the following years grew into the modules that make up Listub today - from shopping lists and tasks to travel, subscriptions, shared expenses and reading trackers, with Lumi, the built-in AI assistant, tying them together. Listub is now live on iOS and Android in 41 languages.

    · Aug 2026

    I used to keep track of my series in a separate app and my lists somewhere else. Listub has a watchlist built in, so now I mark off episodes in the same app where I keep everything else. It tells me when new episodes...

    · Aug 2026

    I had my shopping list in one app, my notes in another and my tasks somewhere else. Listub has all of it in the same place, so I stopped switching around. I mostly just type what I want and it adds it. My partner and...
