How to make an app for an interior designer

Interior jobs run for weeks with many moving parts: measurements, a room-wise quote, material orders, carpenters on site and payments in stages. An app for your studio keeps each home's quote, work progress and money received together, so you can answer a client's call from the site.

Updated 2026-11-09

Who uses the app

The designer and the team: a site supervisor, sometimes the head carpenter. If only you use it, the data stays on your phone. If the supervisor updates progress from the site on their own phone, connect a Supabase database so you both see the same jobs.

The screens an interior designer app needs

Sites: Every running home with the client, locality, stage and the next thing due, such as kitchen shutters arriving on Friday
Quote builder: Room by room items with size, material and rate; the total and a PDF to send to the client
Site progress: Work done per room with dates and photos you attach, and pending items for the carpenter or painter
Materials: Laminates, hardware and plywood ordered for each site, from which supplier, and whether it has arrived
Payments: The advance, the stage payments agreed and what is still due on each site
Clients: Search by name or phone, with call and WhatsApp buttons

Features worth asking for

A room-wise quote with square-foot rates that becomes a branded PDF to share on WhatsApp
Payment stages, for example advance, on material delivery, on carpentry, on handover
A punch list per room for the final round of fixes before handover
Material orders per site with supplier name and delivery status
A progress update for the client as a PDF with dated photos
A WhatsApp button with a ready message for payment reminders

Where the data lives

If you are the only user, the data stays on your phone. If your supervisor or carpenters update sites from their own phones, connect your own Supabase database from the chat. For taking advances online, connect your Razorpay account too; the money goes to you.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Sites, Quote builder, Site progress, Materials, Payments.
Describe it to AppCub. Paste the request below, changed to your own business and details.
Check the plan. AppCub shows the screens and features it will build. Change them in the chat until they are right; seeing the plan is free.
Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
Share it. Share it as a web link, an APK file, or publish it on Google Play from your own developer account.

Copy this request, change the details to match your interior designer, and paste it into AppCub:

Make an app for my interior design studio, Menon Interiors in Kochi. Screens: sites, quote builder, site progress, materials, payments and clients. A quote has rooms; each room has items with width, height, material and rate per square foot, and a total. Make the quote a PDF with my logo to share on WhatsApp. Each site has payment stages: advance, material delivery, carpentry done and handover. Site progress has dated notes and photos per room, and a punch list before handover. Track materials ordered per site and whether they arrived. Beige and dark green colours.

Tips for an interior designer app

Give AppCub your current quote format, even a photo of an old one, so the PDF looks like what clients already get from you.
Fix your item list once: kitchen base unit, wall unit, wardrobe, loft, TV unit, false ceiling. The quote builder becomes quick after that.
Start with sites, quotes and payments. Add materials tracking when the team is used to the app.
Ask for the progress PDF in a simple layout with large photos, since clients mostly open it on their phones.
Try one full quote and one site for a week before adding all your running jobs.

Good to know

AppCub doesn't make 3D renders or connect to design software, and it doesn't send automatic SMS. It keeps quotes, sites and payments, and shares PDFs and messages on WhatsApp when you tap the button.
AppCub builds Android apps. You can also share the app as a web link that opens on any phone; for the iPhone App Store, AppCub’s team can do it for you.

Questions

Can the app make a quotation for a full flat?

Yes. Ask for a quote builder with rooms and items, each with size, material and rate, and the app adds it up and makes a PDF with your studio name.

Can I track which carpenter is on which site?

Yes. Ask for a team list and assign people to sites by date. If the carpenters will open the app themselves, connect a Supabase database so everyone sees the same plan.

Can clients approve a quote inside the app?

That needs a client sign-in and an online database. Most designers send the quote PDF on WhatsApp and note the approval in the app.

Can I keep a photo record of each site?

Yes, you can attach photos to each room with a date, and share them as a progress PDF. Large photos use space, so keep a few per visit.

Can the app tell me which jobs are losing money?

If you enter the quote and the material and labour costs per site, the app can show the difference for each job. It only knows what you put in.

Can clients pay the advance through the app?

Yes, with a payment button on your own Razorpay account after connecting Razorpay and Supabase in the chat. The money goes to your account, not AppCub's.
