A solo-built Flutter habit tracker (iOS/Android) that visualizes streaks as a GitHub-style tile grid, free up to 4 habits with a paid unlock.
Founder-led and organic-led: growth runs on App Store Optimization and the founder's public revenue-recap habit on X, not paid acquisition.
$602k in revenue and 25,100 paying subscribers as of 2025, a 23,543-follower founder X audience, and a 500K+ Google Play downloads badge as of August 2025.
Growth compounds through Apple and Google search rank, not the website: a case-study creator's breakdown credits a keyword-in-app-name plus screenshot-hook ASO approach for its top-3 "habit tracker" rank.

The site draws roughly 44,300 estimated monthly visits, up 10.2% over the last 3 months. Search Organic leads the mix at 46.3%, ahead of Direct at 32.5% and Social Organic at 16.1%, a split where organic search and word-of-mouth-driven direct traffic (people typing the URL or app name from memory) together account for the large majority of visits. The rest, Gen AI referrals and other referral links, totals under 6%.
The most telling ranking targets are "habit tracker app" (6,390 searches/mo, the broad category term) and "habitkit" (5,460 searches/mo, branded demand built from the X following), with "habit kit" (950 searches/mo) as a smaller variant of the same branded search. Among the closest competitors, habitify.me is a direct rival fighting for the same generic "habit tracker" query, reclaim.ai is a broader AI-calendar tool encroaching from an adjacent productivity category, and habitdaily.app is another single-purpose tracker in the same crowded niche, evidence that the category itself is saturated with lookalike apps.
The specific pages earning their organic search traffic, and the pattern behind why they rank. Adapt the format, not the topic.
The organic footprint is concentrated almost entirely on the homepage, which carries the large majority of organic visits and ranks #2 for "habitkit" and #4 for "habit tracker widget." The two blog posts that round out the top pages follow a narrow, feature-specific angle: one targets the "iOS home screen widgets" long-tail keyword directly tied to a product feature, and the other is a personal narrative piece connecting the founder's own marathon training to habit tracking. This is a thin content operation, just three pages carrying the visible organic surface, which suggests the ranking strength comes from the product listing and branded search built by the founder's public following rather than a content-marketing engine.
Not traffic share. How much weight the growth system actually puts on each channel, with a one-line read on the role it plays.
For founder-led SaaS the breakdown shifts from ads to traction: where the first users came from, how the founder grows it in the open, and the compounding organic surface.
HabitKit's traction came from a slow build-in-public grind on X punctuated by one sharp keyword-driven acceleration, not a single launch spike.
A minimal habit-tracking prototype the founder posted to r/androiddev in June 2021, more than a year before HabitKit shipped to the App Store and Google Play on November 27, 2022, scored 166 upvotes and 39 comments, validating interest well before the product existed in its current form.
Monthly build-in-public revenue recaps on X show MRR climbing steadily from $300 in February 2023 to $1,993 by November 2023, the slow linear climb typical of ASO-driven organic growth rather than a viral spike.
January 2024 revenue jumped to $33,201 (+175%) and MRR to $5,606 (+82%), a step change that carried through to a $10,000 MRR milestone by November 30, 2024.
A December 2024 feature in a video from Marques Brownlee's tech YouTube channel MKBHD ("The Studio") triggered a visible spike in sales notifications, per the founder's own account of the moment.
The founder's personal X account, not the @habitkit brand account linked from the homepage, is where the actual audience-building happens.
The channels are not separate. They are one system where each stage feeds the next. Here is the read, then the plays to run tomorrow.
The loop starts on X, converts through app-store search, and compounds through downloads and reviews rather than any paid channel.
the founder's 23,543-follower X audience and organic Reddit mentions surface the app to people who are already habit-tracker shoppers.
App Store and Play Store search for "habit tracker" and "habitkit" branded terms, where the app holds a top-3 "habit tracker" rank per Starter Story's breakdown, does the actual converting, not the website, which draws only ~44,300 monthly visits against a much larger pool of store searchers.
the 500K+ downloads badge reached by August 2025 feeds the review base and store ranking algorithm, a flywheel that keeps reinforcing the same organic surface without added spend.
there's no owned email list or newsletter funnel visible, and the brand's TikTok/Instagram presence is entirely third-party creator coverage rather than a channel the company runs itself, leaving the growth engine dependent on two slow-moving assets: store rank and one person's following.
free-to-paid conversion rate, churn, and blended ARPU.
The proofHabitKit's founder tested a minimal prototype on r/androiddev over a year before the official launch and got 166 upvotes and 39 comments, real signal before writing months of production code.
The adaptationBefore building your next feature or product, post a rough screenshot, mockup, or one-paragraph pitch in the single subreddit or forum where your exact future user already hangs out, and read the comment reactions as your go/no-go signal. The mechanism: a niche community's upvotes and comments are a cheaper and faster demand signal than a landing page with no product behind it.
every build-in-public post in the record comes from Sebastian Röhl's own handle; the brand account exists as a link target but shows no independent posting activity in the evidence.
his signature format is the monthly recap thread, pairing a dollar figure with a percentage change, from the January 2024 recap ($33,201 revenue, +175%) to the $10,000 MRR milestone post that November.
his specific posting map is r/selfhosted (top post scored 331), r/MacOS (90), r/ObsidianMD (81), r/macapps (76), r/iOSProgramming (66), and r/ProductivityApps (23, his only post directly about a habit-tracking concept), showing Reddit builds his personal reputation far more than it drives the product.
a November 2023 post reading "Damn, sorry that I charge for a product that I've put countless hours of work in" drew 140 likes and 34 replies, the kind of unpolished, defensive honesty that reads as authentic to a build-in-public audience.
HabitKit's real search engine isn't a blog, it's the App Store and Play Store listing itself, treated as a ranking surface.
Starter Story's teardown credits two specific moves for the top-3 "habit tracker" rank: putting the primary keyword directly in the app name ("Habit Tracker - HabitKit") and leading screenshots with the most visually distinct feature instead of polished designer mockups, a call the founder validated by A/B testing.
the blog carries only two posts feeding a minority of organic traffic, covered above, confirming the compounding surface lives in store search rather than the open web.
no active Meta, Google, or TikTok ad campaigns appear in the evidence, so paid demand generation isn't part of the mix at all, organic ASO and the founder's personal audience carry the full acquisition load.
Cost: $0 · Time to signal: days · Works pre-PMF: yes
The proofthe founder's recurring MRR and revenue recap posts on X, from a $300 milestone in February 2023 to a $10,000 MRR milestone in November 2024, built an audience that now amplifies every update.
The adaptationPick one platform and post a monthly (or even weekly, early on) update with your real numbers, however small: revenue, users, a single metric that moves. Start the post the same day you have your first real number, even if it's $47. Weave in a moment of doubt or friction occasionally, not just wins, since that's what reads as credible rather than promotional.
Cost: $0 · Time to signal: weeks · Works pre-PMF: yes, provided you're comfortable being transparent about small early numbers; a founder unwilling to share genuine figures won't get the same trust payoff
The proofthe app-name-keyword and screenshot-hook approach covered above earned HabitKit a top-3 rank for "habit tracker."
The adaptationIf you distribute through an app store or any ranked marketplace listing, put your primary search keyword directly in your product's name field, then test your lead screenshot or thumbnail against your most visually distinct feature rather than a generic branded mockup. Ship two screenshot variants and check the store's built-in conversion or impression data after a few weeks.
Cost: under $500 · Time to signal: weeks · Works pre-PMF: conditional, only applies once you have a live store listing to optimize, it doesn't transfer to a pure web product
The proofthe founder's highest-scoring Reddit posts, like the 331-upvote self-hosted DNS thread, have nothing to do with HabitKit, while his one on-topic post scored a modest 23.
The adaptationPost genuinely in communities tied to your personal interests, not your product's category, and let your profile accumulate real karma and trust before you ever mention what you're building. When you do post about your product, do it sparingly and in the community most directly relevant, since an account with no history reads as spam the moment it self-promotes.
Cost: $0 · Time to signal: days for an individual post, weeks to months to build real standing · Works pre-PMF: yes, but capped by each subreddit's self-promotion tolerance, overplaying this risks a ban
The proofa single Starter Story video breaking down HabitKit's ASO approach pulled 3,613 engagements on TikTok, more reach than the brand's owned social accounts show anywhere in the evidence.
The adaptationIdentify a handful of case-study-style creators or newsletters in your space who profile founder numbers and tactics, and pitch them your most specific, non-obvious tactic (not a generic "we grew fast" story) along with a real number behind it. Cold outreach with one concrete mechanic is far more likely to land than a generic press pitch.
Cost: $0 · Time to signal: weeks to months · Works pre-PMF: conditional, only works once you have a genuinely interesting number or mechanic to offer, a creator has no story to tell about a product with nothing unusual yet Not transferable at an earlier stage: the MKBHD feature and the Starter Story creator coverage both required an already-compelling revenue story to attract attention, a brand-new founder can't book that kind of pickup until they have their own defensible number to point to. The early validation post, the recap cadence, and the community-reputation play are available from day one.
