Most-relevant FlutterFlow review
"I hired LunarBuild to build my MVP based on FlutterFlow over a few weeks. Neil is an excellent point of contact, always making sure I had everything I needed. We collectively reviewed the milestones until I felt confident with the result. I'd highly recommend them as a team for FlutterFlow/Firebase MVP development."

We default to FlutterFlow because it's the fastest path for ~70% of the apps founders bring us. Plain Flutter and native iOS/Android are on the table when they're the right tool. Pick the lane that sounds like you.
Founders
v1 milestone in 2 weeks
You have an idea, a deck, maybe a Figma. In 14 days you have a real iOS + Android app on your phone — end-to-end flows working, payments live. Store submission follows in the next milestone.
Native iOS + Android from one codebase
Payments + auth wired on Day 1
Live on TestFlight by week 1
Stuck in FF
Unblock the hard stuff
Native bridge won't compile. Custom widget keeps re-rendering. Stripe and Supabase handshake half-built. We've shipped past every one.
Custom widgets + native modules
Real backends, not toy ones
Performance + memory tuning
FF → production
Polish for the stores
Your FF app works on simulator. Now it needs review-ready polish, analytics, crash reporting, deep links, and a successful submission.
Four things every real Flutter app needs — wired in by Day 14, not "we'll figure that out in v2."
Production binaries
Signed iOS .ipa and Android .aab from one Flutter codebase. Exported Dart, version-controlled, in your GitHub.
Real payments live
Stripe + RevenueCat wired in. Subscriptions, in-app purchases, paywalls, and entitlements that survive App Store review.
Push, deep links, analytics
FCM + APNs push, deep-link routing from notification to screen, PostHog + Sentry from Day 1 — not after the first crash.
Submitted to the stores
App Store + Play Store listings, screenshots, preview videos, and review reps handled. Most apps approved within a week.
Beyond Day 14: custom Dart widgets, Swift / Kotlin native modules, Supabase or Firebase backends, OTA updates — see the process and rescue block.
First milestone risk-free
Progress in two weeks, or it's free.
If you don't see real, working progress at the Day-14 demo, you owe nothing and walk away with whatever we built. No contracts. No retainer lock-in. No "kickoff fees."
14 days from kickoff to a real, working app on your phone — that's the first milestone. Store submission, scaling, and v2 work continue from there at the same milestone-based cadence. Free intro call, fixed quote in 24h, first milestone risk-free.
01
Day 0
Audit + spec
Free 20-min intro call. We sketch the FF project shape, flag anything that needs custom code, and send a fixed quote within 24 hours.
Scope doc + milestone plan
FF audit if you've already started
Fixed-price quote, in writing
02
Day 1–3
FF skeleton
Theme, design system tokens, navigation, auth, and the empty shell of every screen. By Day 3 you can click through your entire app on a real device.
Brand-tuned theme + tokens
Navigation + auth wired
TestFlight + Play Internal builds
03
Day 4–10
Build + custom code
Real screens, real data, real payments. Where FF can't go we drop into Dart, custom widgets, and native modules — same codebase.
Stripe + RevenueCat live
Custom widgets + native modules
Friday demo + Loom every week
04
Day 11–14
First-milestone demo
Working app on a real device. End-to-end flows, payments live, analytics + crash reporting wired in. We walk you through it on a Loom and hand over the build for sign-off.
TestFlight + Play Internal build
Handoff Loom + 1-page architecture doc
Sign-off → next milestone or wrap-up
After Day 14: App Store + Play Store submission, post-launch bug support, and v2 scope — same milestone-based cadence, same flat-fee per milestone. Most projects ship to the stores within another 1–2 milestones.
Why us
We write custom code, not just clicks.
Most "FlutterFlow agencies" are no-code shops who hit a wall the moment your app needs anything novel. We start where they stop.
Official FF Partner
Vetted by FlutterFlow themselves. Direct line to platform engineers, early access to features, and a public listing that's reviewed annually.
Partner-tier support pipeline
Reviewed by FF, not self-claimed
Listed on FF's partner directory
Ex-FlutterFlow engineer
Founded by an engineer who built parts of the FlutterFlow platform itself. We know how the codegen works, what's about to ship, and how to bend the tool when needed.
Insider knowledge of FF internals
Codegen-aware project structure
Migration paths off FF if you outgrow it
Friday demo + Loom every week
Every Friday you get a working build on your phone and a 5-minute Loom walking through what shipped that week. No "I'll have it next week." No black-box weeks. You always know where the build is.
Friday TestFlight + Play Internal build
5-min Loom walkthrough every week
Slack-first comms · <4h response on weekdays
Free · 20 min · Fixed quote in 24h · No deck
Already in FlutterFlow?
Stuck on something FF can't do? We've fixed it before.
We start every rescue with a 2–4 hour audit and a written report — what's healthy, what's risky, what we'd change. Then a fixed quote for the fix or the migration. Most stuck FF apps need three things: a real backend layer, a few targeted custom widgets, and a small native bridge.
Four ways to ship a mobile app. Only one delivers in 14 days.

FlutterFlow vets partner agencies based on real builds shipped, code quality, and client outcomes. Partner agencies get a direct line to the FlutterFlow team, early access to platform features, and a public listing that's reviewed annually. LunarBuild is an official FlutterFlow Partner Agency, led by an ex-FlutterFlow engineer.
Do you only build in FlutterFlow, or do you also write custom code?
Both. FlutterFlow is the fastest path for the visible 80% of an app: screens, navigation, theming, and stock integrations. The other 20% — custom widgets, native modules, complex Stripe or Supabase wiring, performance tuning — we write in Dart, Swift, or Kotlin and plug straight into the FF project.
Why FlutterFlow instead of plain Flutter?
When the visible part of the app is largely standard, FlutterFlow gets you to a working build in days instead of weeks. You still own real Flutter code (we export and version-control it), but you skip the early scaffolding work. For apps that are mostly novel UI or heavy native, plain Flutter is sometimes a better fit — and we'll tell you so on the call.
When is FlutterFlow the wrong choice?
When the app is mostly bespoke graphics, real-time games, AR, or heavy on-device ML. We'll say so on the intro call instead of selling you something we know will fight us later. In those cases we either build in plain Flutter or recommend native.
What do you hand over on Day 14?
Signed iOS .ipa and Android .aab, the FlutterFlow project transferred to your account, the exported Dart code in a GitHub repo on your account (we push to it from Day 1, not Day 14), App Store and Play Store listings drafted, plus a handoff Loom and a one-page architecture doc. No license fees. No platform lock-in. Nothing held hostage.
What if I don't want FlutterFlow? Can you build plain Flutter or native?
Yes. We default to FlutterFlow because it's the fastest path for ~70% of the briefs we get — but plain Flutter, native Swift, and native Kotlin are all on the table when the app calls for it (real-time games, AR, heavy on-device ML, deeply bespoke graphics). Same 14-day first milestone, same fixed quote in 24h, same Friday Loom cadence either way. We'll tell you which tool we'd pick — and why — on the intro call.
Can you fix or scale an existing FlutterFlow project I already have?
Yes. We start with a 2–4 hour FlutterFlow audit and give you a written report on what's healthy, what's risky, and what we'd change. From there we scope a rescue, a custom-code retrofit, or a clean migration. Most stuck FF projects need three things: a real backend layer, a few targeted custom widgets, and a small native bridge.
How does pricing work?
Fixed quote, in writing, within 24 hours of the intro call — once we've walked through scope, platforms, and timeline. One number that doesn't move. No retainer fees, no hourly bait-and-switch, no "kickoff fees." You walk away with a written scope doc either way, even if you don't move forward with us.
