Calendly · 2021–2026
From a link-sharing tool to a Today view
When I joined Calendly, the mobile app was mostly a way to copy your scheduling links, and the people who used it were more likely to churn. From 2021 to 2024 I refocused the app towards what users actually used it for and sold that direction twice successfully. In 2026 I rebuilt it as a place to manage your day and built Calendly’s first mobile design system.

Part 1 · 2022–2024
What should the app do?
Starting out
Calendly pioneered the shareable scheduling link, and the company saw that link as the core of the product. The mobile app reflected that: it was mostly a place to copy and share your links.
The bigger problem was the business side: customers who adopted the app were more likely to churn than people who never touched it. The app had an identity crisis: if you asked three people what the app was for, you’d get three different answers. The realistic path was to just keep the lights on.
We had personas, but they weren’t based on real users, so I set them aside and went to see what people were actually doing.
Where were users finding value?
When I looked at the numbers, what stood out to me was scheduled events usage. It got a lot of use even though we’d given it very little love. Since every phone already comes with a dedicated calendar app, I was curious as to why users were spending so much time here.
Their answers were very insightful. They found their dedicated calendar apps were too noisy, full of other people’s PTO and blocks that often had little relevance to their day. Most Calendly users are professionals meeting external clients. Calendly was the filter on the meetings they actually got paid for.
Two behaviors kept coming up: booking the follow-up during the meeting, while rapport is highest, and checking what’s next and adjusting when a meeting runs long.
An interesting data point
Then I found a number that took me by surprise: about 1 in 5 events were booked by the host, not the invitee. Hosts were copying their own link, opening it in a browser, picking a time and typing in the other person’s details. That’s a workaround that went counter to Calendly’s ‘happy path’ of letting others book with you, and at that volume it meant we’d missed something people did with the product frequently.
Making the case for a new direction
In October 2022 I presented the finding to the whole product org at an offsite. Leadership pushed back hard. When I showed a video of a customer saying they booked 90% of their meetings this way, the room laughed. That night they put our senior data analysts on it, who came back saying that my numbers were conservative. That got me some credibility. The head of product became an ally and gave me the go-ahead to explore some new directions on mobile.
The reframe: we’d been building mobile like a smaller version of web. But people opened the app between meetings, managing what already lived on their calendar as often as they scheduled new events. The Calendly mobile app was for the real-time management of the meetings you get paid for.
I explored three directions. Leadership had suggested a low effort approach of making the scheduled events screen the home screen, but it buried event types and looked empty on light days. The focus view had the right priorities but was trying to do too many things at once. The split view, with relevant meetings up top and event types below, seemed to be striking the right balance.
Having a direction is one thing. Getting permission to build it is another. In early 2023 I tested it with about 40 users and looked at what bets were working and what needed refinement. Then I built the case one person at a time, up to the CEO. He approved it, but I don’t think he was convinced yet. That difference shaped the next three years.

Getting approved didn’t make the project safe. In mid-2023, my PM, the head of product and the CPO all left the company. The new CPO came in with no history with the project, no relationship with me, and an open question about whether mobile deserved any more investment. So I made the case again from the beginning. He funded it, with more engineers than we’d had before. A new PM joined in late 2023, and we spent 2024 building it.
What we shipped in 2024
- A home screen built around today’s meetings. Web has no home screen, so this was where mobile could show what it’s for.
- Book follow-up. The 1 in 5 workaround, turned into a real feature.
- Event types move below, so sharing a link stays quick without taking over the app.
- Simpler cards. What it is and when it’s available, without a row of link buttons.
Results
In October 2024 the new home shipped alongside Calendly’s first in-app purchases. The headline: app users went from more likely to churn to more likely to stay and subscribe above web.
- of mobile subscribers retained at 4th renewal (vs 57% on web)
- 65.6%of mobile subscribers retained at 4th renewal (vs 57% on web)
- Paywall conversion (vs 8.76% on web)

- +6%boost in PSAT scores
The 2024 mobile releases were among the company’s headline results that year, for a product line that had been a candidate for disinvestment three years earlier. The app was featured as App Store App of the Day several times.
Who was signing up?
About 48% of mobile subscribers were net new users who signed up and subscribed on mobile. Another 48% signed up on web and paid on mobile, and most of those, 35% of all mobile subscribers, paid more than 30 days after signing up. That means about 83% of mobile subscribers were net new to the company.
- Signed up and subscribed on mobile
- Signed up on web, paid on mobile more than 30 days later
- Signed up on web, paid on mobile within 30 days
- Signed up on mobile, would likely have paid on web anyway (estimated from previous years)

Shifting towards day of execution
Where things stood
The 2024 home proved the thesis. By early 2026 the app was in good shape: retention had improved and PSAT was above 80%. We didn’t have a PM on mobile, so I set the roadmap. Three things shaped it:
- According to customer feedback and surveys, users wanted more ways to engage and view their contacts.
- Our CEO wanted more emphasis on meeting recaps and denser screens.
- Mobile had never had a design system. The rules mostly lived in my head, and components drifted in code.
So we rebuilt the app around your day, moved scheduling to its own tab, and refreshed every style. The brand team sets Calendly’s colors and type. My job was how they come together on a phone: the layout and hierarchy, the details, how it feels to touch, and the system that keeps it consistent.
Three versions to the Today view
I started with a simple aim: make the home screen more useful for the current day. Each revision improved on the previous, and by the end it had become something new.
What shipped
The core shift: the app went from a home screen to a Today view.
- Today’s focus. AI suggestions and reminders you set yourself, with light buttons for the common actions.
- Daily schedule. What’s coming up and what already happened, with contact insights communicating short facts.
- Meeting recaps. Including the meeting recap thumbnails on the cards drove recap views up 10%.
- Scheduling moved to a dedicated tab. Scheduling got a new home, with a minimal decrease in sharing rates.
Mobile design system and AI tooling
You’ve been seeing pieces of the mobile design system throughout these screens. With AI changing how we build, a mobile design system became a 2026 priority. It’s net new work and about half my scope.
Choosing where to start. I scored candidate components on impact (how often it’s used), effort (how hard it is to design and build) and priority (how much design and engineering needed it). The long-term goal is more than 50, but they don’t carry equal weight, so we started with the basics a coding agent needs to run with.
Checking quality
I make every design decision. The tooling I built checks the work against my bar.
A component audit. I turned our 60-plus item review checklist into a skill that runs in Claude Code or Figma Make. It tests things like dark mode contrast, 200% text and long translated strings.

A pixel diff. Ensuring design to code parity is a different problem. Web uses Storybook to handle this, but Storybook does not have much mobile support, so I used to be comparing screenshots by hand. I worked with engineering on an audit that renders components from code, overlays them on my designs and flags anything over a 2% difference. This has captured bugs we might not otherwise have caught, such as hidden text stylings being applied from legacy code.
Design Implementation Difference
What I’d do differently
In hindsight, I should have designed the mobile design system earlier. A design systems team was intended to eventually take on mobile, but it was never prioritized. As a result, for too long consistency depended on me alone, and older parts of the app drifted. My learning is that when a standard only exists in my head, that’s my cue to build the system.
