Engineering services

The team behind our products, for your product

SlimIoT designs, builds and supports its own connected devices and their apps. The same engineers also work for other companies on hardware, firmware, mobile and web apps and dashboards.

Who publishes what. Apps we build for a client are published in the App Store and Google Play under the client's own developer account and name. The apps published under SlimIoT Technologies Private Limited are SlimIoT's own products, listed on our Products page.

Services

Five things we build for you

Each one on its own, or all of them as one product. The apps and web apps start with a free first version in 10 days.

Dashboards

A live dashboard for any industry

Medical, power, water, maintenance, environment, agriculture, logistics: whatever your devices measure, we bring the data in live and put it on a dashboard your team can act on. Graphs, alerts, roles, reports and exports, on the web and on the phone.

  • Real-time onboarding of device data: Bluetooth, Wi-Fi, cellular, LoRa or an existing API
  • Graphs that update as data arrives, with thresholds and alerts by email, app or SMS
  • Roles for operators, managers and customers; multi-site and multi-tenant
  • Reports and exports for audits, billing and compliance

Mobile apps

Android and iOS apps, first version free in 10 days

Apps that talk to hardware are our home ground: Bluetooth pairing, live signals, offline use, background sync, notifications and store approval. Our own apps are on Google Play and the App Store; open them to see the level of finish.

  • React Native and native modules for Android and iOS, one codebase
  • Bluetooth Low Energy device setup, streaming and firmware updates from the app
  • Sign-in with email, Google and Apple; privacy, data deletion and store compliance handled
  • Published under your account, with the source code yours

First version of your app, free, in 10 days. After a first discussion we build the first version of your app free of charge within 10 days. If you do not approve it, you pay nothing. If you do, we build the full functionality with you.

Web apps

Database-driven web apps, from portals to optimisation software

Multi-user web applications with a proper database, roles, approvals, reports and integrations, up to the complicated kind: our Optimiser finds the cheapest cotton mix that still meets a yarn specification and works out what fits in a shipping container, in what order to load it, and the paperwork. Our rentals platform runs serviced apartments and hotels: properties, availability, bookings, payments and guest check-in, with an admin panel for the operator. Our workforce platform runs three apps for attendance, leave, payroll and field work. SlimYoga is a guided trainer with a camera mirror and a voice coach in English, Hindi and French. Open any of them.

  • Optimisation and planning software: cost minimisation, container packing, scheduling, with the working shown
  • React front ends with Node or Python back ends and PostgreSQL, MySQL or MongoDB
  • Roles and permissions, approvals, audit trails, notifications, scheduled jobs, multi-language
  • Integrations with payroll, ERP, payment and messaging services; hosted on your servers or ours

First version of your app, free, in 10 days. After a first discussion we build the first version of your app free of charge within 10 days. If you do not approve it, you pay nothing. If you do, we build the full functionality with you.

Firmware

Firmware for radios, front ends and sensors

Low-power firmware on Bluetooth, Wi-Fi, cellular IoT and other communication modules, with analogue front ends and sensors for optical, electrical, thermal, motion and pressure signals. To see it working, open the Plawat app: every number on its screen comes from our firmware.

  • Bluetooth Low Energy, Wi-Fi, LTE-M and NB-IoT, LoRa and proprietary radios
  • Analogue front ends for heart, ECG, oxygen and bio-impedance signals; sensor fusion
  • Real-time operating systems, power budgets measured in months, secure over-the-air updates
  • Audio pipelines, DSP and on-device inference where the product needs it
