of shopping. Reliable, scalable, and ready to convert.
Smooth across platforms
Fast under pressure
Ready for promotion spikes
Challenges we solve
The app your store actually needs.
Nothing extra.
We build custom eCommerce apps from scratch — fast interfaces, real-time sync,
and a UX that behaves like
your users expect it to.
Filters load forever
or don't return results.
Backed by queries and async loading that won't block the UI.
Product pages glitch
or reset mid-scroll.
Fixed with indexed queries
and async fetch.
Cart randomly empties
or fails at checkout.
Checkout flow tested
for edge cases.
Push opens the wrong
screen.
Handled with deep links
and fallback routes.

What goes into eCommerce app development?
Speed where it matters.
Every scroll, tap, and add-to-cart is tuned for zero lag. Buyers don't wait — we make sure they don't have to.
Instant load
Touch-stable flows
Fits every form.
Phones, tablets, foldables — the layout holds. Product grids stay sharp and filters behave, no matter the screen.
Adaptive layouts
Responsive storefronts
Built with the real stack.
Jetpack, Kotlin, Compose. No hybrid hacks. Just native tools wired to store logic from the start.
Android-native only
Store-first structure
Prepped for what's next.
Stock changes, promos, Android updates — nothing breaks. The code stays clean and ready to evolve.
Modular system
Safe versioning

What our clients say
Alex Rivers
CEO
Big thanks to the Toimi team! Everything was done thoughtfully, tastefully, and right on schedule. Loved how design and development were handled together — quick approvals, quick launch. Super easy to work with.
Karina Miller
Manager
We came in with a task tailored to our business — and everything was adapted to fit, no templates. What we appreciated most is that they didn't just think about how to build it, but why. You can feel the care in their approach.
Mark Holzman
Manager
We ordered a webinar interface design and a couple of fintech-related things from Toimi — everything was on point. What stood out was that they didn't just deliver, but also suggested ways to simplify. We took notes.
Maria Reed
CEO
We plan to continue working
with Toimi!

FAQ
Didn’t find what you were looking for? Drop us a line at info@toimi.pro.
Is Android always slower to build for?
No — but it's noisier. More screen sizes, more OS forks, more edge cases. We get ahead of it early
so the app doesn't collapse late.
Do we need to support tablets right away?
Not unless it's part of your strategy. We can scope for phones now and layer in tablet support when growth
justifies it.
How old is too old for Android support?
Depends who you're selling to. If your buyers run Android 8, we'll test and tune accordingly — without bloating
the whole build.
Can you hook into what we already use?
Yes. Stripe, Firebase, 1C, Bitrix, your own API — we speak backend fluently. If it has docs, we're good.
What's your role after launch?
We stay in the loop — fixing, adjusting, scaling. Not a handoff. A hand on the wheel.
