OTT app builder: design your streaming app, live

Design your branded streaming app in the browser. Set your logo, colors, corners, menu and home rows, and watch the home, login, profile and splash screens update live on TV, web, tablet and mobile. No sign-up, no code.

A preset replaces the colors, style, menu and home rows. Your name and logo stay.

RentAnOTT launches this as real branded apps for Android, iOS, web and TV, with your catalog, monetization and multi-DRM behind it.

How to design a streaming app that feels premium

Viewers decide in seconds whether an app feels trustworthy enough to pay for. Four choices do most of the work:

  • One accent color, used sparingly. Reserve it for the primary button, the active menu item and progress bars. If everything is orange, nothing is.
  • A background that lets artwork lead. Near-black backgrounds make posters glow and hide banding on TVs. Light themes suit documentary, learning and faith catalogs.
  • Corners that match your brand. Square corners read as cinematic and editorial; pill buttons and round cards read as friendly, which suits kids and family services.
  • Rows in the order viewers need them. Returning viewers want Continue watching first. Live and sports services should lead with Live now.

One brand, four screens

A streaming brand has to survive very different screens. On a TV, viewers sit three metres away with a remote, so the menu is a side rail and the focused button wears a ring. On the web, a top menu and a pointer take over. On phones, the menu becomes a tab bar with room for five items. Check your theme on all four before you commit to it.

Check contrast before you ship

The builder scores your palette against WCAG contrast ratios: (lighter + 0.05) ÷ (darker + 0.05), using the relative luminance of each color. Aim for 4.5:1 for text and 3:1 for the accent against the background.

From preview to production

A theme is the easy part. A launch also needs encoding, DRM, payments and apps in the stores. Read how to start a streaming service for the full sequence, then model the business with the OTT revenue calculator.

FAQ

Common questions

Do I need design or coding skills to use the OTT app builder?

No. Every control is a color picker, slider or switch, and the preview updates as you change it. Start from one of the five presets and adjust from there.

Which devices can I preview?

Four: a TV app with a remote-friendly side rail, a streaming website with a top menu, a tablet app and a phone app with a bottom tab bar. Each one shows four screens: home, login, the profile picker and the splash screen. The same theme drives all of them, so you see how one brand adapts to each screen.

Is my logo uploaded anywhere?

Not while you design. Your logo is read by your browser and shown in the preview only. If you create a share link, a copy resized to at most 512 pixels is stored with your theme so the link can show it to whoever opens it. The exported JSON never includes the logo.

Can I share my design with my team?

Yes. Share saves your theme and logo and gives you two short links. The preview link opens a working demo app in your design on a full page: visitors can scroll, open titles, sign in and press play, and switch between TV, web, tablet and mobile. It has no editor, which suits clients and stakeholders. The edit link opens the builder with your design loaded. You can also copy or download the theme as JSON design tokens.

Can I choose which sign-in methods the login screen shows?

Yes. The Login tab lists email, phone number, Google, Apple and Facebook. Show or hide each one and change the order with the arrows; the first method becomes the primary button on the login screen.

What do the contrast checks mean?

They measure the WCAG contrast ratio between your colors. Body text should reach at least 4.5:1 against its background, and the accent should reach 3:1, so that menus, buttons and titles stay readable on a TV across the room and on a phone in daylight.

Can RentAnOTT turn this design into a real app?

Yes. RentAnOTT launches white-label streaming apps for Android, iOS, web and TV under your own brand. Send the share link or the theme JSON with your demo request and the team will use it as the starting point for your apps.

Are the movies and shows in the preview real?

No. Every title and poster in the sample catalog is fictional. They are there so you can judge your theme against realistic artwork. Your real app shows your own catalog.
