The bottom line
App growth comes from word of mouth, which means making users look good when they share and driving downloads through influencers and partners. Tracked links show which of these channels actually pays.
Key takeaways
- Word of mouth only works once an app has users who love it. 2:50
- Only a percentage of users love a product enough to recommend it to friends.
- An app with about 10 downloads a day should skip K factor and find product market fit first.
- Users share an app when sharing makes them look good. 3:20
- Zero sends a weekly report (126 hours fasted, 7 fasts, 100% of goal) with a pre-filled "Tweet this" button.
- Calm shows a quote after meditation, and Crossy Road makes a shareable gif of a top score.
- Influencers drive app downloads at scale. 6:36
- 74% of consumers have bought a product because an influencer recommended it.
- Cal AI used many influencers to reach over $20M a year.
- Partners in the same niche can reach buyers through order confirmation emails. 6:54
- A yoga app can ask a yoga clothes store to add it to order confirmations, with 25% off the first year or 60 free days.
- Order confirmation emails get very high open rates.
- Tracked links show which influencer or partner actually drives results. 8:00
- A deep link tool like Airbridge gives each influencer their own link and shows downloads, but not revenue.
- A custom product page in App Store Connect adds download and sales data for each influencer.
If you make people look good, they're more likely to talk positively about you.

Chapter summaries
0:00 Three channels, one idea
Influencers, referrals and partners all count as word of mouth, and each needs its own tactic and its own tracking.
- K factor measures how far an app spreads from user to user. 0:30
- It counts how many people download an app and then share it with others.
- Steve P. Young groups influencers, referrals and partners under this one idea.
- The plan is to cover the best tactic for each channel, then how to track whether it works.
- App Masters says it has served over 3,000 apps and also runs a podcast.
- Social media posts drive purchases, so skipping content leaves money on the table. 1:30
- 76% of users have bought, or meant to buy, a product after a social media post.
- He counts YouTube as social media and built his businesses on this channel's content.
- He found most of the stats by searching Google.
2:40 Make users look good when they share
Apps get shared when the app builds a shareable, flattering moment into its own flow.
- Games spread when a score turns into something worth posting. 4:04
- Flappy Bird spread through screenshots of scores and frustrations.
- Crossy Road users post their top-score gifs on Twitter.
- Flappy Bird was probably one of the first apps where people shared screenshots this way.
- The gif is fun content in its own right, so sharing it feels natural.
- Wellness apps spread when users can show their progress. 3:31
- People post Calm's post-meditation quote under #dailycalm on Instagram.
- Zero lets users photograph a finished fast, such as 18 hours.
- Sharing the quote is a way to spread positivity, so the sharer looks good.
- Steve has shared his own long fasts this way.
5:18 Influencer marketing
Influencer-led growth works because people already buy on creators' recommendations, and apps can track it with offers.
- Apps can track influencer sales by giving referred users a special offer. 5:44
- "TikTok made me buy this" is now a popular ad format.
- One app the team dissected used affiliate marketing and gave influencer-referred users two weeks.
- Steve estimated the affiliate approach and got partial confirmation.
- He says this tracking method isn't required and promises a better one.
6:09 Influencers and niche partners
Influencers and partners in your niche put an app in front of people who already care about the topic.
- Partners can be stores, newsletters and blogs in your app's niche 6:52
- The tip came from a past podcast guest who tried it, and it worked well for him.
- A yoga app can approach a store that sells yoga mats or yoga clothes.
- Cal AI's founder Zach explained his influencer approach on the My First Million podcast.
- The partner's offer can be any trial or discount that fits your app.
8:00 Tracking links with Airbridge
One tracked link per influencer, plus a custom product page, shows both downloads and sales.
- Each influencer gets a link made in a few clicks 8:21
- An MMP can make these links too, but a deep link tool is the cheaper route.
- Create a link, name the channel in lowercase (here appmasters), and add it as a custom channel.
- The channel can be video content or word of mouth. It is simply the influencer.
- With no Android app, the link sends those users to the website.
- After you hit create, you get a short version of the link to send.
- A custom product page shows whether an influencer drives sales 9:37
- Custom screenshots can match the influencer, so their audience sees a familiar fit.
- It can carry its own description and promo text for that influencer.
- If you only track downloads, the default page is fine.
10:58 Deep links inside the app
A deep link can open a specific screen and show who referred the new user.
- Showing the referrer's profile on onboarding raises conversion 11:01
- In a delivery app like Uber Eats, the invited friend sees Welcome Adam, Steve invited you with Steve's photo.
- A deep link can take users to any specific part of the app.
- This makes it more versatile than a plain download link.
