the CLEAREST path to building a $100k MRR mobile app
(from a guy who's advised apps that have gotten hundreds of millions of downloads)
step 1: pick a habit (already crushing)
– the fastest path to $100k MRR isn’t inventing something new, it’s cloning what already works.
– proven habit categories: fitness, journaling, language, meditation, finance.
– people already pay here, they expect daily use, and habits = sticky revenue.
step 2: add the AI unlock
– once you’ve got the habit, layer AI on top to create a “wow” moment competitors don’t have.
– examples:
- journaling app → AI reflects back themes in your writing like a therapist
- fitness app → AI vision corrects your form in real time
- finance app → AI predicts overspending before it happens
- language app → AI roleplays conversations in voice/video
step 3: freemium + subscription model
– free tier must give immediate value (otherwise no word-of-mouth, no viral content).
– paywall for deeper features or unlimited usage.
– price:~ $5/week
– annual plans with discounts (40–50%) drive cash upfront.
- test copy, screenshots, paywall timing relentlessly. it can 3–5x your LTV.
step 4: distribution = TikTok + IG + creators
– build a playbook of 20+ organic TikTok/IG posts tied to your use case (Duolingo memes, Notion desk setups, Strava challenges).
– hire a part-time creator (or be one) pumping out 3–5 clips a week. volume matters.
– partner with micro-influencers (10k–100k) who feel authentic to your niche... stay true to a CPM that works for you ~$5 for example
– run paid TikTok/IG ads → optimize for cheap installs (<$2).
- start with English-speaking Tier 1 markets for ARPU, but layer Tier 2 markets for cheap volume. you’ll find CPI in LatAm/India <$1. Even Canada, Australia etc are cheaper than the US.
step 5: paid search/ASO
- apple search ads and google uac are the hidden workhorses for mobile apps.
- search ads catch users with high intent right in the app store (“journaling app,” “habit tracker”) and consistently convert 2–3x better than social, while uac spreads across google, youtube, and play store to drive cheap installs at scale (especially in tier 2 markets).
- pair both with aso (titles, screenshots, reviews) so the keywords you buy also lift your organic rankings.
step 6: retarget everything
– pixel every install/visit and run retargeting on TikTok, IG, YouTube, Reddit.
– 90% of users won’t pay on day 1. retarget with product clips + testimonials.
– cost of acquisition drops dramatically once you layer retargeting across channels.
- implement Amplitude/Mixpanel, Firebase, Superwall, RevenueCat early so you actually know which creative, cohorts, and experiments are moving numbers.
step 7: design viral loops inside the product
– exportable content: if it’s fitness → progress screenshots, if it’s journaling → daily streaks, if it’s learning → shareable quizzes.
– leaderboards, streaks, or badges that push people to flex on social.
– make sharing feel like part of the product experience, not an afterthought.
step 8: retention flywheel
– onboarding is everything. get to the “aha” moment in <2 minutes.
– nudge users with daily push notifications that feel like a friend, not spam.
– weekly emails with progress reports (“you saved 4 hours this week” / “you learned 27 new words”).
– community layer (Discord/Reddit-style group) to reinforce habit loops.
math to $100k MRR (at $5/week, $4 CPI)
$5/week ≈ $22/mo per sub.
need ~4.6k paying subs to hit $100k MRR.
at 8–10% conversion → need 46–58k active installs.
assume ~50% of installs stay active → ~92–116k total installs.
at $4 CPI → $368k–$464k in ad spend (gross).
so: $400k-ish in paid media to reach $100k MRR at $4 CPI… unless you juice it with organic virality, influencers, or geo-arbitrage (Tier 2 markets <$1 CPI).
tldr;
- app store gold rush 2.0 is here. ai + paid search + aso = unfair leverage. the window won’t stay open long.
- find ideas in your own life or grab them from @ideabrowser's website (free/paid plans)
- note: building any startup isn't easy
- mobile apps felt dead for years. now they’re alive again.
- this is the most generational time to build since 2008-2013 mobile app heyday.
people will make fun how long this tweet is.
but if you've gotten this far...
i hope this fires you up
i hope this gets your creative juices
i hope you share this with a friend
happy building
i'm rooting for you.
