**The product.** A phone app. The user photographs a room, a house front or a garden, picks one of ten modes (Redesign, Refresh, Furnish, Declutter, Paint, Flooring, Materials, Lighting, Outdoors, Staging) and a style, and gets back an AI-made picture of the same space with the change applied. A setting called structure lock tells the image model to keep the walls, windows and doors where they are.

**Why it worked.** It is a small, honest example of a one-developer app store business on top of a rented image model. The payment processor data shows the whole revenue curve: almost nothing for two years, about US$300 a month after a relaunch in late 2025, then a slow fall to about US$100 a month in 2026.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

Restyle AI, called RoomStyler AI until September 2026, is an iPhone and Android app for AI room redesign: the user gives a photo of a real room, and an image model returns a new picture of the same room in another style, with new paint, new floors or new furniture. The developer, Borys Kuśmirek in Wrocław, Poland, published the first store version in August 2023. The app's privacy policy says the photos are sent to OpenAI's image models.

The revenue is read through RevenueCat, a service that records in-app purchases and subscriptions from the Apple and Google stores. TrustMRR, a site that shows revenue read directly from such services, listed US$2,216 of revenue since launch on 6 November 2026, US$2,050 of it in the last 12 months, and US$113 of monthly recurring revenue (MRR, the subscription revenue that repeats each month) from 40 active subscriptions. The best month was January 2026 with US$369; October 2026 brought US$97.69.

This is a very small business, and the page shows it as such. Since February 2026 the developer has listed the app for sale on TrustMRR at US$3,000. Interior redesign is a crowded app category: the App Store page shows ten similar apps under "You Might Also Like", and the site already has larger stories in the same group.

## Pricing

Restyle AI in-app purchases on the US App Store page, read 6 November 2026 (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Premium (App Store item 1) | not stated | 4.99 | Billing period not shown; up to 150 designs a day |
| Premium (App Store item 2) | not stated | 9.99 | Billing period not shown; up to 150 designs a day |
| Premium (App Store items 3 and 4) | not stated | 29.99 | Billing period not shown; up to 150 designs a day |

The App Store page lists four in-app purchases, all named Premium, without their billing periods. The terms of service (11 August 2026) say the PRO plans are weekly, monthly or yearly, that the price is shown in the app before purchase, that it can vary by region, and that a PRO subscription is the only way to generate designs: there is no free allowance. PRO allows up to 150 designs a day with a 30-second wait between them. The Google Play page shows no prices.

How to read this table: a grade A value was read by TrustMRR from RevenueCat, the service that records the app's store purchases. A grade C value is the developer's own text (store listing, terms, TrustMRR profile text). A "calc" value was computed on this page from the rows above it.

## When did Restyle AI (formerly RoomStyler AI) launch, and how did it grow? Timeline

From a first store version in August 2023 to a rebuilt, renamed app in September 2026. Each entry carries its grade.

- **25 August 2023** (grade B [2]): Version 1.0.6, the oldest entry in the App Store version history, is published.
- **August 2023 to November 2025** (grade calc [1, 2]): No new versions appear in the history. Revenue before December 2025 adds up to about US$166.
- **29 November 2025** (grade A [1, 2]): Version 1.0.7, the first new version in the history; from version 1.0.8 (11 December 2025) the release notes say 'updates AI models'. Revenue reaches US$304 in December 2025.
- **January 2026** (grade A [1]): Best month: US$369 of verified revenue.
- **15 February 2026** (grade C [1]): The developer lists the app for sale on TrustMRR; the asking price is US$3,000.
- **11 August 2026** (grade C [4]): New terms: generating needs a PRO subscription, the old credit system ends, and PRO is capped at 150 designs a day.
- **20 September 2026** (grade C [2]): Version 1.5.3: renamed Restyle AI, rebuilt, ten modes, structure lock, one paywall instead of five.
- **6 November 2026** (grade A [1]): US$2,216 of verified revenue since launch, US$113 MRR from 40 subscriptions.

## Why did Restyle AI (formerly RoomStyler AI) work?

### A narrow promise

The store text names one weakness of general image models: asked to restyle a room, they often redraw the walls and windows too. The app's answer is structure lock, an instruction to the model to keep the architecture, and a Compare view so the user can check the result. The selling point is control, not a new model.

### Rented model, owned workflow

The privacy policy says the images go from the app's Firebase Cloud Functions to OpenAI. The developer owns the modes, the style catalogues (14 styles, 24 wall colours, 10 floors, 10 materials, 8 lighting setups), the prompts behind them and the paywall.

### Store distribution

The TrustMRR profile names app store optimization as the marketing channel: users find the app by searching inside the App Store and Google Play. The privacy policy also mentions the TikTok Events SDK to measure the developer's own ads.

### Subscription only

Since 11 August 2026 there is no free generation and no credit system. Every design needs a PRO subscription, which limits cost per user with a cap of 150 designs a day.

## How it was built

These details come from the TrustMRR profile, the store pages, the terms and the privacy policy. They are the developer's own statements.

- Flutter for one code base on iPhone and Android, according to the TrustMRR tech stack.
- Firebase for anonymous sign-in, Cloud Storage, Cloud Functions, Analytics, Crashlytics and Remote Config (used for A/B tests of features and prices), according to the privacy policy.
- OpenAI image models for every generated picture, called from the developer's servers.
- RevenueCat for subscriptions and purchase checks; TikTok Events SDK for ad attribution, only with the user's consent on iOS.
- No user accounts: an anonymous identifier is tied to the device, so designs are lost when the app is deleted, as the terms warn.

## Who tried this before Restyle AI (formerly RoomStyler AI), and why did they fail?

Four companies in our database of failed startups promised affordable interior design before image models could redraw a room from a photo. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Modsy (2015 to 2022; funding US$72.7M; cause: Unit Economics)

- Promise: Upload photos of a room and get photorealistic 3D renderings with furniture from partner retailers, for US$69 to US$199 a room.
- Why it died: Human designers spent hours on each design, customer acquisition was expensive and customers rarely came back, so costs grew with every order.
- Record: 

### Laurel & Wolf (2014 to 2019; funding US$25M; cause: Unit Economics)

- Promise: Online interior design from professional designers for a flat fee.
- Why it died: The flat fee did not cover customer acquisition, and quality fell as the designer network grew.
- Record: 

### Tastemaker (2012 to 2015; funding US$1.5M; cause: Competition)

- Promise: On-demand interior design from online designers for middle-income households.
- Why it died: Service quality depended on a distributed workforce of designers, and better-funded competitors offered the same with more technology.
- Record: 

### Kujiale (2011 to 2025; funding US$550M; cause: No Market Need)

- Promise: Cloud 3D room design and furniture placement for consumers and furniture companies.
- Why it died: The database says most buyers wanted experts to design for them rather than a design tool, and newer AI tools made its rendering technology less valuable.
- Record: 

## What changed

Modsy, Laurel & Wolf and Tastemaker sold the same wish, to see a room redesigned before spending money, but each design needed a human designer or hours of 3D work. That made every order expensive, and the failed-startup database records say unit economics or competition ended all three.

An image model now does the redrawing in under a minute, for the price of one API call. That lets one developer offer a redesign app for a few dollars a week. It also lets anyone else do the same: the App Store page lists ten similar apps, and the TrustMRR data shows that this app's revenue fell by about three quarters from its best month.

## Can one person copy Restyle AI (formerly RoomStyler AI) now?

**Verdict: Yes, technically. Making real money from it is the hard part.**

One developer built and runs this app with Flutter, Firebase, RevenueCat and a rented OpenAI model, so the build is within reach of one person. The verified revenue shows the problem: US$2,216 in 39 months, and about US$100 a month in late 2026, in a category with many look-alike apps.

1. Pick one clear failure of the general model (here: it moves the walls) and make the fix the product.
2. Give the user a way to check the result, such as a before and after comparison.
3. Use a subscription with a daily cap, so one heavy user cannot cost more than they pay.
4. Connect the payment data to a public verifier early, so a later buyer can trust the numbers.

**What is still open.** Sellers of real estate and furniture shops need the same before and after pictures in bulk, inside their own tools; a business version with listing-photo rules and a shop's own product catalogue is less crowded than the consumer app stores.

## What could go wrong for Restyle AI (formerly RoomStyler AI)?

- **Small and falling revenue.** TrustMRR shows US$369 in January 2026 and US$97.69 in October 2026, and MRR fell 17.5% in the 30 days before 6 November 2026. The developer has offered the app for sale at US$3,000 since February 2026 (TrustMRR).
- **Competition.** The App Store page lists ten similar room redesign apps, and on this site MyRoomDesigner.AI and DecorAI sell the same idea with larger verified revenue.
- **Dependence on OpenAI.** Every design is made by OpenAI's image models, according to the privacy policy. A price change, a quality change or a policy change at OpenAI changes the product and its margin directly.
- **Ratings reset and an old complaint.** The App Store page says the overall rating 'was recently reset' and shows 0 ratings in the TrustMRR store data. The one visible review, from 11 December 2025, is titled 'Scam' and says the user was charged before the free trial ended and that generations failed. The developer replied that the paywall had wrongly advertised a free trial on a plan without one, and that this and the failures were fixed in the 1.5 rebuild.
- **Other apps by the same developer.** The App Store and Google Play list other apps by Borys Kuśmirek, among them a hair and scalp scan app (Hairloom), a blood pressure log, a breathing app for anxiety, and SlideFarm, which auto-posts slideshows to TikTok. This page judges only Restyle AI; its own store pages and terms do not sell or link to those apps.
