Frequently asked.
Why wouldn't I just hire a full-time developer?
Hiring a senior Flutter developer full-time costs $120K–$180K+ per year, plus benefits, onboarding time, and management overhead. With Spark, you get senior-level output for a flat monthly fee — no payroll taxes, no months of recruiting. You also skip the risk of paying for hours when there isn't enough work to keep them busy.
What do I actually get delivered?
A production-ready Flutter mobile app for iOS and Android. Full source repo on your GitHub, store-ready builds, icons, splash screens, and release notes. 60fps animations and native-feel transitions.
Who is the developer?
A senior Flutter dev with 8 years of experience building production apps at scale. All coding is done by me personally and is never outsourced. Designs and animation work are the only things that get handed off, to vetted specialists I've worked with for years.
Is there a limit to how many requests I can make?
Once subscribed, you can add as many development requests to your queue as you'd like, and they're delivered one by one. Generally we focus on one task at a time so things actually ship.
How fast will I receive my completed work?
On average, most requests are completed in two days or less. More complex feature requests can take longer — we'll break larger tasks down into manageable milestones that ship continuously.
What if I don't like the result?
No worries. We'll continue to revise the code until you're 100% satisfied. Unlimited revisions exist for exactly this reason.
Can I pause my subscription?
Yes. Pause anytime through the billing portal. You'll keep your remaining days and resume whenever you're ready. Cancel just as easily.
Who owns the code?
You do, 100%. I push to your GitHub from day one. Everything is yours: code, designs, accounts, the lot.
What's NOT included?
I don't build custom backends or stand up servers. Backend needs go through Supabase or Firebase (which I'll wire up as part of the work), or you bring your own backend ready for integration. Also not included: ongoing app store account management, paid ad creative, and anything outside the mobile app codebase itself.
Who pays for 3rd party services like Firebase and RevenueCat?
You do. Any 3rd party backend or SaaS costs (Firebase, RevenueCat, OneSignal, Supabase, cloud hosting, etc.) are your responsibility. Before launch, you'll link your own billing accounts so I'm not charged for your app's usage.
