Toronto, Canada
A focused mobile studio in Toronto. Our apps for Trackforce, CLEIO, Kaira, and RE-AK are used by 2 million+ people every day, with a 99.5% crash-free rate across every launch. We work where reliability is the product: guarding, healthtech, fintech, and banking.

Through dedicated projects and team extensions, our engineers have shipped production mobile apps for these companies.
DEVSFLOW is a mobile studio based in Toronto, building for guarding, neuro healthcare, fintech, and beyond. Every engineer ships mobile code daily. That focus means faster delivery, fewer bugs, and apps that perform where it matters: spotty connectivity, strict compliance, and hospital-grade reliability.
What Clients Say
Zawar joined CLEIO's Android development team on an engagement through DEVSFLOW Technologies and quickly proved himself to be a dependable, communicative, and professional consultant. He integrated smoothly into the project team, ramped up on the project context efficiently, and consistently delivered against the cadence set by the client.
“Thank you for the reliable application you delivered, not a single failure since I've been using it.”
“Thank you Zawar, for the work you've done resolving revenue-impacting issues from the Tracktik mobile app.”
“Thank you Zawar, it has been a real pleasure working with you. I wish you the best in your projects!”
Two engagement models, both built around how technical teams actually operate. No black-box handoffs, no surprises at demo day.
End-to-end delivery from architecture to App Store. We own the full mobile stack so your internal team stays focused on backend and business logic.
Best for: New products, legacy app rebuilds, or MVP-to-production transitions.
Senior mobile engineers embedded directly into your existing workflows. Your repo, your standups, your sprint cadence. No ramp-up friction.
Best for: Teams behind on roadmap, pre-launch surges, or filling a senior mobile gap.
No spec docs back and forth for weeks. We get into your codebase and your standups quickly, then keep you in the loop the whole way.
Day 1
Not a sales call. You describe the problem, we ask the technical questions that determine whether this is a good fit. If it isn't, we say so and point you somewhere better.
Days 2 to 7
If you have a codebase, we read it. If you have a spec, we read that. Either way you get back a one-page scope with assumptions, timeline, and a clear "here is what we will and will not do."
Week 2 onward
Engineers join your existing tools (GitHub, Jira or Linear, Slack). Bi-weekly demos with working builds on your device. Same workflow as a senior internal hire, no separate "agency review" cycle.
Launch week
We handle App Store and Play Console submission, set up Crashlytics or your preferred crash reporting, and tag the release for rollback if anything misbehaves.
After launch
If you have an internal team, we do a real handoff with documentation and a one-week overlap. If you don't, we roll into a maintenance engagement that keeps the app healthy through OS updates, dependency drift, and policy changes.
We don't claim to know every industry. We know the four where we've shipped real production apps and seen what reliability actually costs.
Offline-first mobile apps for security guards and field teams operating where connectivity is not guaranteed.

Common questions
Most production iOS and Android apps we build land between $80,000 and $300,000 CAD, depending on scope, hardware integration, and compliance requirements. Smaller scoped MVPs can start around $40,000. We do not quote a number without reading your codebase or spec first, because numbers based on guesses are always wrong.
A typical single-platform mobile app takes 3 to 6 months from kickoff to App Store. Hardware-connected apps (BLE, sensors, EEG) take longer because they sync to firmware cycles. We start every engagement with a one-week scoping phase that produces a defensible timeline.
Depends on what the app does. For apps with BLE, sensors, sustained background work, or camera pipelines, we recommend native. For simpler content and forms apps that need fast iteration across both platforms, React Native is often the right call. We tell you honestly which fits, even when it costs us a deal.
Yes. Most of the apps we maintain were built by other teams. We start with a codebase audit during onboarding, document the architecture and risks, then take over crash monitoring, OS update testing, dependency upkeep, and the bug fix queue.
Toronto, Canada. We work with Canadian and US clients in the EST and CST time zones, which gives us same-day standup overlap with most North American teams. Five of seven team members are in Toronto, two are in Calgary.
From 6-week senior engineer placements through multi-year mobile builds. We do not take on projects under a 6-week runway because there is no time to do the codebase or scope work properly.
Hiring a senior mobile engineer takes 3 months minimum, plus a ramp month. If you need capacity sooner or only for a defined project window, embedding a DEVSFLOW engineer through our staffing engagement lets you ship in week one. If you want to convert someone full-time after, we have a path for that.
No forms, no gatekeepers, no SDR rotations. Email or call directly and hear back from a real engineer within one business day.
