I am Masaki Hirokawa. I have been building solo apps since 2014, mostly in the wallpaper, healing, and lifestyle categories, and I have run them long enough to learn what really matters once they live on the store. The "half a day to a working app" feeling you get from Rork is genuinely revolutionary — but if you ride that momentum and submit straight to review, in my experience it almost never passes the first time.
Between "the app runs" and "the app sells on the store" there is a finishing workflow that is almost invisible until you have shipped a few times. Rork's output is an excellent foundation, but if you care about long-term operation and revenue, there is a layer of careful work to add on top. In this article I am sharing the finishing workflow I keep returning to, condensed into ten checkpoints.
This list is not Rork-specific. It is a guide for taking any AI-generated codebase to the state of "an app that actually makes money."
1. Sharpen the icon and app name
Rork generates names and icons that are good enough as prototypes, but not necessarily good enough to compete on the store. I spend more time here than people expect.
I judge icons by whether they make a thumb stop scrolling in a row of search results. Concretely, I open Figma, line up my icon next to competitor icons at the actual thumbnail size, and check it. Color contrast, silhouette legibility, whether the symbol still reads at thumbnail scale. Tightening this can roughly double first-week installs in my experience.
For the app name, I aim at a balance between search keywords and a memorable proper noun. A pure keyword stack ("XX wallpaper") never builds into a brand. A pure proper noun never gets discovered. The "proper noun + short keyword" structure is what has worked best for me over the years.
2. Lock down privacy and tracking declarations
Out of the box, the privacy disclosures the stores require are usually empty. iOS especially has tightened around tracking and personal data, and a vague answer here is a near-guaranteed rejection.
The minimum I always fill in:
- App Tracking Transparency declaration (whether IDFA / advertising ID is used)
- Types of personal data collected and their purpose (analytics, crash reports)
- Privacy policy URL (required)
- Terms of service URL (recommended)
You can have AI draft a privacy policy, but always read through it against your actual app. Templates frequently leave in items you don't actually collect — that mismatch is also a rejection risk.
3. Plug the recurring rejection patterns
Apple and Google reject apps along a fairly predictable set of patterns. From the rejections I have personally absorbed over the years, here is what I now check on every Rork-generated app before submission:
- Does the app demand a login at launch with no strong reason? (Apple dislikes unjustified account requirements.)
- Do the description and the actual implementation match? (If you say "Pro unlocks X", X must really unlock.)
- If there is paid content, is there a "Restore Purchases" button visible?
- Are the terms of service and privacy policy reachable from the in-app settings?
- If there are external browser links, does their behavior match what the description says?
These items are not "needed for the app to work" but they are "needed for review to pass." Rork won't take care of them automatically, so I treat them as non-negotiable items on the pre-submission checklist.
4. Bake in crash reporting from day one
The thing most often pushed to "after launch" is crash reporting. From hard experience, this is exactly the wrong order, especially as a solo developer.
When a user leaves a "the app doesn't work" review, you have nothing to act on without logs. With a tool like Crashlytics in place, you immediately know that the crash only happens on a specific device on a specific OS version. For an indie operator, removing the time spent reproducing problems is the single biggest force multiplier.
I add to whatever Rork generates: a minimal crash reporter and lightweight analytics for the basic events (launch, key screens, purchase complete). Nothing fancy. The goal is just "if something happens, I can reconstruct what happened."
5. Don't ship machine translation as-is
Rork's multi-language scaffolding is convenient, but anything sitting on machine translation needs human eyes before launch. In particular, when you ship to languages beyond English and Japanese, off-tone copy is read as "this app is sloppy" and shows up in your conversion numbers.
My approach: I review English and Japanese myself, and for the rest I ask an AI like Claude or ChatGPT to evaluate it as "would this read naturally as store-facing marketing copy?" You don't need perfection. Just removing the obviously unnatural lines noticeably changes how international users perceive the app.
Localization compounds in revenue terms. The world outside your home market is multiples larger, so the payoff for taking this seriously is real.
6. Design AdMob placements into the layout from the start
If you plan to monetize with ads, plan the placement at design time. Slotting ads in afterward warps the user flow and damages the experience.
What has consistently worked for me:
- Pin a banner where it never obstructs the main flow (bottom or below the home content)
- Show interstitials only at natural action-completion beats — never back-to-back
- Use one or two native ad slots blended into content lists, not more
The principle is: don't sprinkle ads in. Designate "this is where an ad lives" from the beginning. The apps I have run for years sustain roughly ¥1.5M / month in AdMob revenue (2024–2025) on this foundation, while staying clean enough that users keep using them.
7. Subscriptions: design value as a three-step ladder
If you ship subscriptions, structure the value as a three-step ladder: free / monthly / lifetime (or yearly). Two steps feel forced; four or more confuses people into bouncing.
Decide explicitly per step what is unlocked: ads removed, features added, content opened. A vague "Pro" bucket leaves users guessing what they get and kills purchase intent.
When layering IAP onto a Rork-generated app, mark the boundary in code from the start. I keep a single function like isPro() and have the UI side read only its return value. That makes future expansion — and refactors — much cheaper.
8. Place the review prompt right after a "win"
Store star ratings move installs more than almost anything else. The trick to the rate-this-app prompt is to fire it at moments where the user is feeling "this app is good."
Concretely, good moments include:
- After three or more completions of a core action
- Right after a positive interaction like "favorite" or "save"
- 10–30 seconds into a session where they obviously haven't bounced
The wrong moments are immediately at launch and immediately after an error screen. I have firsthand experience of an app's rating tanking when I got this wrong. Be conservative — but always anchor the prompt to a positive context.
9. Raise the resolution of your store screenshots
Rork can autogenerate screenshots, but as a competitive instrument, this is a place I always retake the wheel. My layout rule:
- Slot 1: a single-line value statement + a hero screen
- Slot 2: a top-down view with three main features arranged together
- Slots 3–4: close-ups of individual features
- Slot 5: a slot that shows what you do that competitors don't
If slot 1 fails, slots 2–5 never get seen, so I spend most of the time on slot 1. The headline rule: write what the user gets, not what the feature is. Not "500 wallpapers" but "every day, a different mood."
10. Set the post-launch rhythm before you launch
Finally, plan the operational rhythm before you ship — not after. My solo-dev cadence looks like this:
- Daily: skim crash reports and 1- and 2-star reviews (about 5 minutes total)
- Weekly: review installs, revenue, and retention summary (about 15 minutes)
- Monthly: ship one update — either a feature or a fix
Locking in this minimum cadence is what turns an app from "a piece of work that gets abandoned" into "a service that keeps growing." Monthly updates particularly matter — both for the store algorithms and for trust with users.
The "half a day from idea to app" feeling Rork delivers is incredible. Whether that turns into a sustainable product depends almost entirely on the operational discipline you put on top of it. The flip side is also true: if you take this finishing workflow seriously, Rork becomes a foundation that holds up for the long haul.
