AZUKI makes fashion-tech apparel — cooling vests with mini-fan technology that cut heat by 10–12°C and heating vests that run 35–55°C, built to Japanese technology standards. TechTack built its native iOS and Android app: a mobile shopping experience that explains a technical product clearly and turns interest into purchase, on both stores.
AZUKI doesn't sell ordinary clothing — it sells wearable technology. A cooling vest with a built-in fan, a heated jacket with a temperature range. Products like that don't sell themselves from a thumbnail; they need to be explained.
When the product is technology you wear, the app has one job: make the technology make sense — then make it easy to buy.
So AZUKI needed more than a catalogue. It needed a native app, on both iOS and Android, that could show how the tech works, let people compare options, and back it all with real proof — videos and reviews.
The challenge
A cooling vest that drops 10–12°C or a jacket that heats to 55°C is a genuinely different product — and that's both the opportunity and the problem. A shopper has to understand what it does and trust that it works before they'll buy.
The app had to carry that load on a small screen: explain the technology clearly, present a catalogue of technical apparel, let people compare options for their conditions, and provide proof through videos and real reviews — all delivered natively on both iOS and Android so no customer is left out.
What the app does
A focused shopping app built around understanding a technical product and acting on it.
Explain the technology
Rich product detail makes the tech tangible — how the mini-fan cooling cuts heat 10–12°C, how the heating range works — so a shopper grasps the value before they buy.
Compare and choose
Easy browsing and product comparison help customers pick the right item for their weather and their work, instead of guessing between similar-looking products.
See it in action
Instructional videos and reviews from real users provide the proof a first-time buyer of wearable tech needs to feel confident.
Support and stay connected
24/7 online support plus news and community keep customers helped after purchase and engaged with new launches.
How we built it
A mobile build where explaining a technical product clearly mattered as much as the shopping flow itself.
- 1
Designed around the product's tech story
We built the product experience to teach as it sells — surfacing temperature specs, mini-fan cooling, and how each item performs, so the technology is obvious, not buried.
- 2
Built native for iOS and Android
A consistent native experience on both platforms, so AZUKI's full market gets the same quality regardless of device.
- 3
Made comparison effortless
Clear catalogue and comparison so customers can match a product to their conditions and pick with confidence.
- 4
Backed it with proof and support
Instructional videos, real user reviews, and 24/7 support designed into the experience — the trust signals a wearable-tech purchase depends on.
- 5
Shipped to both app stores
Published and maintained on the App Store and Google Play, so the app stays available and current for every customer.
The result
AZUKI is live on both stores — free on the App Store and Google Play — giving the brand a native mobile channel that explains its fashion-tech products and sells them to iOS and Android customers alike.
For a brand whose products are genuinely new, that's the point: an app that does the explaining, so the technology gets the shot it deserves.
