On 13 August 2026, WAYA launched. Four days later it was the number one free iPhone app in Ghana.

WAYA is the messaging and social app launched by Shatta Wale as "the African way to connect". We designed it, built it and still run it: the iOS and Android apps, the web client, the real-time backend and the calling infrastructure. A celebrity launch is exciting. It is also the hardest test an app can face, because the audience arrives all at once, on day one, with high expectations and no patience.

Here is what we learned getting WAYA through that week, and what we would tell anyone planning a big launch.

1. You are compared with WhatsApp from the first minute

Nobody downloads a new messenger because they have nothing to use. They already have WhatsApp, and they will judge you against it before they have sent their first message.

That set the bar for day one. The basics had to be finished, not "good enough for version one": messages that arrive instantly, delivery and read status, replies, reactions, edits and deletes, voice notes, photos, videos, documents and view-once media. A launch audience does not read release notes. If something they use every day elsewhere is missing, they assume the app is broken.

The lesson: list the habits your users already have, and make sure the first version respects every one of them. Novelty comes second.

2. Real time has to survive real networks

WAYA had to work for people switching between Wi-Fi and mobile data, often on a weak connection. A chat app that works perfectly on office Wi-Fi can still fail its users every day.

Chats, presence and delivery status run over WebSocket connections, so they stay live without the app constantly asking for updates. Voice and video calls run over WebRTC and reconnect automatically when the network changes, so walking out of the house does not drop the call. Incoming calls use native alerts, so they ring on the lock screen like a normal phone call. Media has to upload on a weak connection too.

The lesson: test on the networks and phones your customers actually use, not the ones your team uses. Build for reconnecting from the start, because adding it later means rewriting the core.

3. Finding your friends should not cost your privacy

A messenger is empty until your friends are on it, so onboarding has one job: connect you to people you know, quickly. The easy route is to upload the user's whole address book. We did not want WAYA to start its relationship with users that way.

Instead, people can find each other by name, username or verified email, or through privacy-preserving contact matching. Friend requests, mutual-contact hints and verified badges for public figures make it clear who you are adding. On top of that sit the controls people now expect: who can discover you, what notification previews show, muting, blocking, reporting, and deleting your account from inside the app.

The lesson: trust features are launch features. Privacy controls, blocking and reporting are not a phase-two nice-to-have for a social app. They are part of what people check before they invite their family.

4. Fans want a place to hang out, not just to message

A launch driven by a fan movement brings expectations a normal launch does not. People did not just want to send messages. They expected stories, a feed and verified badges, and for the app to simply not fall over.

So stories sit above the chat list, and a Discover tab adds For You, Following and Latest feeds with comments, reposts, saves and creator suggestions. The app is a place to hang out, not only to message.

The lesson: understand why people are really coming. For WAYA it was community as much as communication, and the feature list had to reflect that.

5. Plan for the spike, not the average

WAYA's launch did not grow gradually. It had to carry a spike from zero to tens of thousands of sign-ups in hours, and every one of those people hits the same few steps at the same moment: sign-up, verification, finding friends, and the first push notification.

Here is how we would tell anyone to plan for a launch like that:

  • Find the expensive steps. Sign-up, contact matching and media processing do the most work per user. They are the ones to rehearse under load.
  • Move slow work out of the user's way. Anything that does not need to happen before the next screen should run in the background, so a busy minute makes things slower rather than broken.
  • Watch the reviews as closely as the servers. Store reviews and social media often show what real users are struggling with faster than any dashboard.
  • Keep the team on call. The first 72 hours are when small problems become one-star reviews. Someone who can fix them needs to be awake.

Today WAYA has a 4.5 rating from 145 App Store reviews, runs on iOS, Android and the web, and every feature is still free.

Planning a launch of your own?

Whether it is a messenger, a marketplace or a booking app, the question to ask is not "does it work?" but "does it work when everyone arrives at once, on the phones and networks they really have?"

We have built for launch day more than once, from WAYA to Shaxi. If you have a launch coming up, tell us about it and we will tell you honestly where the risks are. See how we approach mobile app development and DevOps and infrastructure.
