How to Use Your Phone to Manage Your Home Renovation or Decorating Project

Home renovation and decorating projects have a way of expanding beyond their original scope, running over budget, and producing stress disproportionate to what was supposed to be an improvement project. The organisational challenge is significant: multiple suppliers, decisions to make, dimensions to remember, progress to track, and a budget to maintain.

Your phone can manage most of this if you know which tools to use.

Measuring: The AR Measure App

Both iPhone (Measure app, pre-installed) and Android (Google AR Measure or Samsung Quick Measure) can use augmented reality to measure dimensions using the phone camera.

Point the camera at a surface, mark the start and end points, and get a dimension. Accuracy is sufficient for rough planning (±5-10% in good conditions) but shouldn’t replace a tape measure for precise cuts or ordering.

More useful: the ability to take a photo and annotate it with dimensions directly in the Measure app. A photograph of a room with key dimensions marked on it is far more useful than a list of numbers.

Visualising Before You Commit

AR apps allow you to see how furniture and decor will look in your actual space before buying.

IKEA Place: puts IKEA furniture in your room through your camera. Surprisingly accurate for scale.

Houzz: has an AR feature for visualising furniture and decor in your space.

Several paint brands have apps (Dulux Visualiser, Benjamin Moore Color Portfolio) that let you virtually paint your walls in any colour from their range.

These tools prevent the expensive mistake of buying something that looks wrong in the actual space.

Shopping and Sourcing

Create a shopping list in a shared Google Sheets document or a dedicated app like Sortly. Share it with anyone else involved in the project so everyone sees the current list.

Pinterest boards are useful for collecting inspiration and reference images that communicate the aesthetic you’re going for to contractors, decorators, or family members who need to understand your vision.

Google Lens: point your phone at a tile, fabric, fixture, or colour in real life and it searches for the same item or similar items online. Useful for finding the source of materials you’ve seen somewhere and want to buy.

Budget Tracking

Create a simple budget spreadsheet with categories: materials, labour, fixtures, contingency. Update it as you spend. Keeping a running total tells you where you stand relative to budget in real time rather than discovering you’ve overspent when the project is complete.

For larger projects, there are dedicated renovation budget apps (Buildbook, CoConstruct) but a Google Sheets spreadsheet is sufficient for most home improvement projects.

Progress Documentation

Photograph everything before, during, and after. This serves several purposes: before photos remind you of how bad things were and document the starting point for insurance. During photos document what’s behind the walls before they’re closed (where pipes and cables run), which can be invaluable for future work. After photos document your investment for insurance and, if you ever sell, for estate agents.

Use a consistent location and angle for before/after comparison shots. Create a dedicated album for the project.

Contractor Communication

WhatsApp group with your contractors: creates a single reference thread for all project communication, photos, and decisions with a permanent searchable record. Better than emails that get buried and phone calls where decisions aren’t documented.

Before a contractor starts any significant work, document what’s been agreed in writing in the WhatsApp thread: scope, timeline, cost. This creates a record that protects both parties.

Managing Multiple Decisions

Renovation projects involve constant decisions: handle vs handleless cabinets, which grout colour, which light fitting. Making decisions under pressure leads to choices you live to regret.

Keep a running “decisions needed” list on your phone. For each one, note the deadline (when you must decide for the project to proceed), gather reference images and notes, then decide by the deadline. Having the decision context in your phone means you can decide during a commute or lunch break rather than derailing work time.
