Compare PlansBUSINESS AUTOMATION
Whatever's leaking time or money, we automate it.
Quotes & lead follow-up
A lead comes in while you're on a job. The system replies, sends the quote, and books the next step so the work doesn't go to the next company on the list.
Answers on your website
A chat on your site that handles the common questions, captures the lead, and books a time — using your services, your prices, and your service area.
Workflow automation
Connect the tools you already use. A new lead comes in, gets sorted, lands in your CRM, and a follow-up goes out. Nobody copies it over by hand.
Paperwork & invoices
Pull the details out of documents, sort incoming requests, ask happy customers for reviews, and chase the invoices that haven't been paid.
If the job is repeatable, we can automate it. Need the phone answered 24/7? That's a separate product: NeverMissAI. The app, the website, and the workflows are what we build here.
CUSTOM APP DEVELOPMENT
iOS, Android, and web apps — native and cross-platform.
Native iOS & Android Apps
Custom Swift and Kotlin app development for performance-sensitive products with polished, platform-native UX.
Cross-Platform App Development
React Native, Flutter, and Kotlin Multiplatform (KMP) app development — one codebase, multiple platforms, faster time to market.
Web App & SaaS Development
Responsive SaaS applications, internal tools, and product dashboards built on modern web stacks.
Backend APIs & App Deployment
REST APIs, CI/CD pipelines, App Store submissions, monitoring, and release operations — all managed async.
Automation & Integration
Connect your tools, automate quotes and follow-ups, and replace the manual steps that eat the day.

ASYNC OPERATING SYSTEM
How an async software development agency replaces meetings with momentum.
1. Add requests to queue
You drop tasks into a shared board (feature, fix, refactor, release step). We prioritize with you and execute one active build item at a time per lane.
2. Get async progress drops
You receive concise updates, commit links, and Loom walkthroughs every 24-72 hours depending on task complexity.
3. Review and continue
Share feedback directly in the task. We iterate immediately, then move to the next queued priority. Meetings are optional, not required.
This model works best for ongoing product evolution, post-MVP growth, and founders who want consistent output. See engagement options or how the process works.
SCOPING GUIDELINES
App development cost — what shapes your quote.
MVP baseline
- One platform (web or mobile)
- Up to 5 core screens and key user flow
- Authentication, data models, one external integration
- Production deployment + 14-day launch support
Factors that increase budget and cycle time
- Additional platform in the same sprint
- Complex role/permissions and workflows
- Offline sync, advanced media, or real-time features
- Enterprise compliance, SLAs, and deep automation
Every project is quoted up front after a free audit and architecture pass, and you approve it before anything starts — no hourly billing. See how engagements work or review projects we have shipped.
FAQ
Frequently asked questions about automation and app development.
What does SwiftAppLab do?
We're a software agency. We build custom apps and websites, and we automate the repeat work: quotes, bookings, reminders, review requests, and unpaid invoices. You get a free audit, then a quote you approve before we start.
I need someone to answer the phone. Is that this page?
Phone answering is a separate product: NeverMissAI. It starts at $97/month, answers the call, books the job, and texts you the details. This page is the software agency.
How does pricing work?
No fixed package prices. Every engagement is scoped to your business on a free audit, then quoted within 24 hours as a one-time setup plus a monthly subscription — the same shape whether it's automation, a new app build, or an ongoing dev lane. No hourly billing. Get a custom quote.
What can you automate for a small business?
Lead replies and quoting, booking and reminders, review requests, and invoice follow-up. If a task is repeatable and eats your time, it's a candidate. Get a free audit.
What does async mean in practice?
You add tasks to a shared request queue and we execute them in priority order. You get frequent updates with no dependency on recurring meetings.
Can you build for web and mobile at the same time?
Yes. Depending on package, we can run parallel lanes for web and mobile or deliver one platform first and expand in the next cycle.
Do you support native and cross-platform?
Yes. We support native iOS/Android builds and cross-platform delivery with React Native or Flutter based on product goals.
What is included after launch?
Deployment, release support, bug fixes, and growth iterations can continue under monthly async plans.
How does an app development agency actually work?
Design, code, QA, deploy, maintain — end-to-end. Read our pillar: What an app development agency actually does (and how to pick one in 2026) covers the four pricing tiers, a 10-question vendor checklist, and red flags to avoid.
How does SwiftAppLab compare to Toptal and other freelance marketplaces?
Different shape of work. Marketplaces place contractors; we ship managed outcomes. See our 10 best Toptal alternatives comparison for an honest pricing matrix and a four-question decision tree.
