## 00. Context. What is Numo?

Numo (ex-Mindist) is a Ukrainian startup that creates apps for people with ADHD. The Flagman app is Numo ADHD, also there’re White Noise, Kawaii Tasks etc.I worked on NUMO ADHD – app for tasks gamification & support. Bite-size educational content with memes. Social and ADHD-friendly to-do.

## 01. Constant research

### User Research

I interviewed users across various app usage stages, from introductory discussions to churn-related calls. Additionally, I spent several days initially handling support tickets.

### Competitors analysis, direct and not

Analyzing other (mostly boring) ADHD apps and services, productivity, well-being and just gamified apps.

### Topic immersion

Exploring how the ADHD brain functions, embracing neurodiversity, investigating gamification, and researching tactics and strategies for managing ADHD symptoms

```

## 02. Selected features and flows

### Friend Invitation

Numo believed in user support and teamwork. I created a fun invite system for new users and to group existing ones into Squads (small groups of users).

```

### Task creation

Even though users want more task features, our analytics show they mostly just 'brain dump'. So, I'm spicing up the features while keeping things simple, hiding the tricky stuff under the hood.

### Learning stories rework

I revamped the UI by creating fresh backgrounds, adjusting color themes and typography. Plus, I introduced the new NeuroReading feature.

### Streaks rework

I created a streaks-sharing feature and developed a part of the new guided tour that explains how streaks function.

## 03. User Acquisition adventure, 40% growth

I revamped the web funnel, attracting users from Facebook ads. In the new version, I experimented with the quiz rhythm and added more social proofs like charts, user stories, and a countdown. And generate a lot in Midjourney 🙃

\
After three A/B tests, web funnel **CR to trial increased by 37% (3.75% → 5.16%).**

### Client has a robust service that empowers restaurants to create personalized delivery websites. They want us to enhance it with QR Payment functionality, allowing for seamless offline payment experiences at restaurants. In this collaboration, our primary focus was on the payment process, particularly the splitting of bills, while ignoring the ordering flow.

### 

**Discovery.** So we started from food-tech market and competitors research. Also we sought out the best interface practices and insights from other domains such as banking and finance management to create universal but convenient bill splitting.

```cv

{"layout":"hscroll","images":[{"src":"https://firebasestorage.googleapis.com/v0/b/maitake-project.appspot.com/o/pages%2FA5Ct93kWyFN4Uu0Pg3yEJDJ3NBW2%2FwizQRXNjjKu625VnXIvz%2Faa9ab4a4-0d76-4342-a18b-e07b2017c324.png?alt=media&token=b38a6f02-ffb7-4a47-84d6-d0d269e0a80b","id":"aa9ab4a4-0d76-4342-a18b-e07b2017c324","width":2200,"height":1096,"filename":"steps.png","type":"image/png","caption":"","border":false}]}
```

**User flow.** Through extensive research and collaborative workshops with client team, we gained insights to define key scenarios, features, and restrictions. Utilizing this knowledge, we crafted user flows and developed prototypes tailored to three distinct roles for each type of bill split.

```cv

{"layout":"hscroll","images":[{"src":"https://firebasestorage.googleapis.com/v0/b/maitake-project.appspot.com/o/pages%2FA5Ct93kWyFN4Uu0Pg3yEJDJ3NBW2%2FwizQRXNjjKu625VnXIvz%2F583e95f5-0ebc-47f0-b652-723b38ba8c94.png?alt=media&token=4cf7ffd6-f0dc-4869-b54c-b065cb305bbd","id":"583e95f5-0ebc-47f0-b652-723b38ba8c94","width":2784,"height":1347,"filename":"User flow..png","type":"image/png","caption":"","border":false}]}
```

**Order and pay.** Device identification simplifies the process — guests select and pay for their individual bill from a shared table.

```cv
gallery
{"layout":"hscroll","images":[{"src":"https://firebasestorage.googleapis.com/v0/b/maitake-project.appspot.com/o/pages%2FA5Ct93kWyFN4Uu0Pg3yEJDJ3NBW2%2FwizQRXNjjKu625VnXIvz%2F0320d28e-2326-4ed5-980e-54816d2a965c.png?alt=media&token=4333b587-a2db-4d99-98d0-57be25b66812","id":"0320d28e-2326-4ed5-980e-54816d2a965c","width":2784,"height":2017,"filename":"2columns orange.png","type":"image/png","caption":"","border":false}]}
```

**Under the hood.** But what when guests need to share the bill? Or pay for someone else? Did someone order for someone who didn’t scan the QR? Considering it we used gamification mechanics that create collaborative space.

```cv
gallery
{"layout":"hscroll","images":[{"src":"https://firebasestorage.googleapis.com/v0/b/maitake-project.appspot.com/o/pages%2FA5Ct93kWyFN4Uu0Pg3yEJDJ3NBW2%2FwizQRXNjjKu625VnXIvz%2F862452ee-6599-4075-8d09-637d8e7b8060.png?alt=media&token=3a162956-27b3-43dd-b870-41b330007ff7","id":"862452ee-6599-4075-8d09-637d8e7b8060","width":2784,"height":2311,"filename":"Details 5.png","type":"image/png","caption":"","border":false}]}
```

**Select items.** First sharing option that allow select specific items rom full list. After one initiate this split other guests should just select their items. It suit for cases where one guest ordered for all, but everyone want to pay for themselves.

```

**Free amount.** We offer freedom to contribute any desired amount towards the bill. Our system dynamically tracks and displays the remaining balance to complete the total bill.

```

**Details.** Our approach to feedback prioritizes not only addressing common issues, but also addressing rare cases, errors, and empty states, ensuring a comprehensive experience. Attention to small details is key to creating a cohesive and seamless experience for the user.
