Standard applications (smart light bulb, smart outlet, simple sensor) — Tuya, Ayla, and Particle are sufficient
Are you a manufacturer of boilers, air conditioning systems, lighting, machinery, or control systems? Your product works fine, but customers can’t control it from their phones. KG Electronics (25 years in business) commissioned us to develop an app—the result, as shown in the case study: customers keep coming back, asking for "the one with WiFi.".
You approve the prototype. We won't start building the MVPithout your approval. Once approved: another 30%.
Weeks 4–7
iOS and Andswarmd app, backend with telemetry, admin panel, and OTA ready for deployment. Weekly iterations on a real device. After the MVP release: another 30%.
Week 8
Release on Google Play and the App Store. Onboarding the first customers. Handing over the code and deploying it to your environment. After deployment: final 10%.
A customer in a store deliberately chooses your controller because they see that it comes with an app. The distributor asks for the price "with the app included." The manufacturer’s brand appears on the first screen—not the flyers.
Alerts from the device are sent to the service panel. Planned replacement, not reactive. Fewer trips to the customer, fewer complaints, shorter failure repair time.
You can see how customers actually use the device—which features, at what times, and what errors they encounter. The second generation of the product is built on data, not on R&D guesswork.;.
A driver bug? Remote update for the entire fleet. A new feature? Push it to the app without returning the device. Faster iteration, lower support costs.
Real customer, real devices, real reviews in the store. You can download the KG app and check for yourself.

7 questions
Before you send the brief, read through the 7-question checklist we use to evaluate ourselves. A comprehensive guide for decision-makers—what sets an IoT software development company apart from a regular one, and when to choose a custom solution versus a ready-made platform.
Two paths, two different manufacturer profiles.
Choose a ready-made platform
Choose Custom IoT
Standard applications (smart light bulb, smart outlet, simple sensor) — Tuya, Ayla, and Particle are sufficient
The customer sees the Tuya logo, not yours
Fewer than 1,000 devices in total; no plans to expand into Western markets
A Polish device with its own protocol (gas controller, air conditioning, dedicated machine)
The customer sees your logo, not someone else's
Over 5,000 devices, a 2–3-year development plan, integrations with Polish ERP systems and services
