AccuLevels — Precision Measurement Mobile App

AccuLevels — Precision Measurement App for iOS and Android

AccuLevels turns a smartphone into a precision measurement tool — using the device's built-in accelerometer and gyroscope to deliver real-time leveling, angle measurement, and inclination readings for professionals and DIY users.

Vasilkoff built the full cross-platform app, handling sensor integration, UI design, and App Store / Google Play submission.

What We Built

Cross-Platform App (iOS & Android)

Built with React Native for simultaneous iOS and Android delivery from a single codebase — without compromising on sensor accuracy or UI performance. The app runs smoothly on a wide range of devices and OS versions.

Native Sensor Integration

AccuLevels relies on precise readings from the device accelerometer and gyroscope. We implemented native sensor access through React Native's sensor APIs, with calibration logic to account for device-specific variance and deliver consistent, reliable measurements regardless of hardware.

Real-Time Measurement Display

A clean, readable interface showing live level and angle data — updating in real time as the device moves. The display is designed for practical use: large, high-contrast readings that are easy to interpret on a job site or workshop, not just in a demo environment.

Precision Tools

Multiple measurement modes including:

• Spirit level — horizontal and vertical
• Angle measurement — precise degree readings
• Inclination / slope — for ramps, roofs, and graded surfaces
• Surface level check — multi-axis simultaneous reading

Calibration System

A user-accessible calibration flow that allows the app to be zeroed against a known reference — important for professional use where factory sensor defaults may not be sufficiently precise for the task.

App Store & Google Play Submission

Full submission handling — app metadata, screenshots, privacy policy, content rating, and review compliance for both platforms.

The Result

A reliable, accurate measurement utility used by tradespeople, contractors, and DIY enthusiasts — available on both major platforms with consistent performance across device types.

Executive Summary

Precision leveling and measurement utility app for iOS and Android — uses device accelerometer and gyroscope sensors for real-time angle and level readings. Built with React Native by Vasilkoff. The engagement demonstrates how we translate a specific buyer need into a usable, supportable product rather than stopping at a visual concept or technical prototype.

The Problem

The underlying job was to give mobile product teams a clearer and more efficient digital path through the workflow represented by AccuLevels — Precision Measurement Mobile App. The product needed to make the core task understandable to users while giving the operator a practical foundation for delivery and future improvement.

Why It Was Difficult

The product had to remain usable across real devices while managing platform constraints, release requirements, performance, and a compact touch interface. The team also had to make sensible trade-offs around the technologies and product scope available at the time of delivery.

Our Solution

AccuLevels is a precision measurement and leveling utility app for iOS and Android. Vasilkoff built the cross-platform React Native app using device sensors — accelerometer, gyroscope — to deliver accurate real-time level and angle measurements for professionals and DIY users. Published on App Store and Google Play.

Vasilkoff owned the work across product structure, implementation, integration, and launch preparation. Decisions were made around the real operating constraint: shipping a coherent product that people could use, not accumulating a long list of isolated features.

What We Delivered

• One cohesive mobile app covering the documented core user journey
• A responsive, production-oriented interface and the application logic behind it
• Integration and operational work needed to move from concept to a deployable product
• A maintainable foundation that could be extended without rebuilding the entire experience

Results

• The engagement progressed from a product requirement to one delivered, usable software experience.
• The shipped scope combined multiple disciplines—product, interface, engineering, and launch readiness—under one accountable team.
• A public product or project artifact is available at play.google.com/store/apps/details?id=com.acculevels.app&hl=en.
• Exact commercial metrics from this historical engagement are not published; the documented functionality and available artifact are the proof used here.

Technical Highlights

The work covered mobile interaction design, platform integration, release-ready implementation, and the supporting services needed by the app. The documented stack included Mobile App, iOS App, Android App, React Native, Utility, selected to fit the product rather than to showcase technology for its own sake.

Transferable Value For Clients

This project is relevant to organisations that need a mobile app shaped around a real workflow, with one senior team responsible for both the visible experience and the systems behind it. The same approach applies when an existing process must be simplified, digitised, or prepared for a broader rollout.
