A cloud digital signage system has two parts: a web dashboard where you manage content, and an app on each screen that downloads that content and plays it. Change a video or a price in the dashboard, and every screen you own updates, whether it sits in Kochi, Dallas or Riyadh. If you want your own platform instead of renting one, digital signage software development at Sigosoft starts at $5,000 for a custom build, with hosting billed separately.
I’m writing this because signage is one of the areas where our team has shipped real, working products. We built the Flutter TV app that Dolphin Digital uses for advertising screens across the United States, and we built the full Medicino platform in Kerala, where clinic TVs call patient tokens with a voice announcement and play ads in between.
Key takeaways
- What it is: a cloud dashboard (CMS) plus a player app on each TV or media player.
- What it does beyond ads: token calling, queue display, menu boards, staff dashboards, patient education, emergency alerts and more.
- Custom vs SaaS: tools like Yodeck or OptiSigns suit businesses with a few screens. A custom build makes sense when you want to sell ad space, connect screens to your own software, or run a white-label network.
- Cost with Sigosoft: from $5,000 for a custom build, hosting extra.
- Delivery: we build, deploy and support the software remotely for clients in any country; hardware and installation are handled locally.
What is cloud digital signage software?
Cloud digital signage software is a system for managing content on many screens from one online dashboard. Content is uploaded to the cloud, scheduled, and delivered to an app running on each screen, which stores it locally and plays it even if the internet drops. Operators can update, monitor and report on every screen remotely.
How does a cloud signage system work?
Every system we’ve built follows the same basic chain.
- The CMS.
A web dashboard where an operator uploads videos and images, builds playlists and sets schedules, for example a breakfast menu until 11 am and a lunch menu after. - The cloud backend.
Stores content and schedules, and knows which screen belongs to which location or client. - The player app.
Runs on an Android TV box, Fire TV stick, smart TV or other player. It downloads the playlist, stores it locally and plays it on loop. - A real-time channel.
For content that can’t wait for the next sync, such as a token number or an emergency message, the server pushes an update to the screen within a second or two. - Monitoring.
Each screen reports back that it is online and what it played, so the operator can spot a dead screen without driving to the store.
On our signage builds we use Kotlin and Flutter for the TV side, with Firebase, Pusher and AWS on the backend. Kotlin gives us tight control on Android TV hardware, while Flutter lets one codebase cover different devices and screen sizes. I covered the Android side in more detail in our post on building scalable digital signage systems with Android TV and Kotlin.
Case study: the Flutter TV app we built for Dolphin Digital (USA)
Dolphin Digital runs an in-store advertising network in the US. On its own website, Dolphin reports more than 3 billion monthly impressions, over 20,000 venues under contract, a presence in 45+ states and more than 150 DMAs, spanning grocery, convenience, pharmacy and retail locations.
In 2024 we built the Flutter TV app that plays Dolphin’s advertisements on its screens, and it is still in use. Sigosoft’s scope was the player app; Dolphin’s CMS and audience measurement tools are separate systems.
Two problems shaped the build. The first was screen variety. Venues across a national network don’t install identical hardware, so the app had to render ads correctly on different screen sizes without a separate version for each. That was the main reason we chose Flutter.
The second was connectivity. A screen at a checkout lane can’t depend on the store’s internet staying up. If an advertiser pays for a slot and the screen goes blank because the Wi-Fi dropped, that’s lost revenue. We built offline playback so the screen keeps running from stored content, and remote monitoring so Dolphin can see which screens are online and playing.
Case study: Medicino, token calling and ads on one clinic TV
Medicino is a healthcare platform used by private and public clinics and hospitals across Kerala. We built the whole platform: the patient app, the doctor app and the TV app.
Here’s how the TV side works. A patient books a token. When the doctor is ready, they call the next patient from the doctor app; its Play Store listing describes calling patients with the token feature to keep the waiting room organised. The waiting-room TV immediately shows the new token number and plays a voice announcement, so patients looking at their phones still hear their number. Between calls, the same screen runs advertisements. Medicino’s own marketing team handles enquiries from advertisers.
The hardest requirement was speed. A token call that appears ten seconds late creates confusion at the doctor’s door, so the update has to travel from the doctor’s phone to the waiting-room screen almost instantly while the ad loop keeps running underneath.
This model is proven at scale elsewhere. In the US, PatientPoint runs the largest point-of-care ad network in the country, with 145,000 screens in 32,000 medical offices, and pharma spend on point-of-care marketing reached roughly $1.2 billion last year according to the Point of Care Marketing Association. Medicino combines that advertising model with an operational tool the clinic needs every hour, which is why the screen stays switched on. We’ve written about similar queue display needs in our post on developing a telemedicine app for Singapore.
Where is digital signage growing around the world?
Estimates differ depending on who you ask. MarketsandMarkets projects the global digital signage market to grow from USD 21.4 billion in 2025 to USD 28.88 billion by 2030, while Grand View Research puts 2025 at USD 31.1 billion. The more useful question is where screens are paying off.
United States.
The largest single market; Grand View Research says the US held the largest share in 2025. Retail media networks like Dolphin and healthcare networks like PatientPoint show two different ways to make screens pay for themselves.
United Kingdom.
Supermarkets have turned stores into ad networks. Tesco announced its 1,800th in-store screen in late 2023, across 420 stores. More recently, Morrisons agreed a seven-year partnership with Bauer Media Outdoor for 300 digital advertising screens at store entrances, live from early 2026.
Saudi Arabia and the UAE.
Mordor Intelligence estimates Saudi Arabia held about a third of Middle East and North Africa DOOH spend in 2025, backed by Vision 2030 transport and smart-city projects, and projects the UAE to grow at around 13% a year through 2031.
Africa.
Growing from a smaller base, but quickly. Mordor Intelligence projects Africa to post the strongest growth in the Middle East and Africa region, at 11.69% a year from 2025 to 2031, and IndexBox estimates South Africa, Nigeria and Kenya account for roughly 60 to 65% of regional large-format display demand. Unstable connectivity makes offline playback essential here.
India and Asia-Pacific.
MarketsandMarkets expects Asia Pacific to record the highest growth rate, driven by retail expansion and infrastructure development. Clinic token screens are one of the most practical uses we see in India.
What can a TV app do besides advertising?
Many of the screens that earn their place do something operational. One Research and Markets report notes that banking, hospitality and transport businesses in the Middle East and Africa use signage for queue management, digital menus and information kiosks. The uses worth looking at first:
- Queue and token display for clinics, hospitals, labs, bank branches and government service counters, ideally with voice announcements.
- Patient and customer education in waiting rooms, mixed with paid ads.
- Menu boards that update prices and hide sold-out items from one dashboard.
- Staff dashboards showing sales targets, production counts or delivery status, pulled live from the company’s own systems.
- Hospitality screens for lobbies, conference rooms and event schedules.
- School and college notice boards that update from one place.
- Prayer time displays calculated automatically by location for mosques and Gulf offices.
- Emergency messages that override every playlist at once during a drill or evacuation.
The common thread: the screen shows information people need right now. Ads work best as a layer on top of that.
Should you build custom signage software or use SaaS?
Most small businesses don’t need custom software. Yodeck advertises plans starting at $8 a month and runs on Android TVs, browsers and its own Raspberry Pi player; OptiSigns offers more than 140 content apps including weather, Power BI and YouTube; and Xibo offers a CMS with cloud hosting and player software.
| Off-the-shelf SaaS | Custom build | |
| Best for | A few screens, standard content | Ad networks, white-label platforms, screens tied to your own software |
| Upfront cost | Low | From $5,000 with Sigosoft |
| Ongoing cost | Monthly fee, often per screen | Hosting and maintenance |
| Integrations | Built-in apps | Anything, including your booking, POS or ERP |
| Branding | Vendor’s platform | Your own |
| Ad sales and proof-of-play | Limited on most plans | Designed around your model |
Custom makes sense when you want to sell advertising on your screens (like Dolphin), when the screen is part of your own workflow (like Medicino’s token calling), when you’re a reseller who wants your own branded platform, or when per-screen fees across hundreds of screens cost more over a few years than a one-time build. Do that last calculation with real quotes before deciding.
How much does digital signage software development cost in 2026?
At Sigosoft, a custom signage build starts at $5,000. Hosting is billed separately, because the right setup depends on how many screens you run and how much video they play.
What pushes the price up:
- The number of platforms the player app must support
- Whether you need a new CMS or a player that connects to an existing one
- Real-time features such as token calling and voice announcements
- Integrations with booking systems, POS, ERPs or your own apps
- Advertising features such as client-level scheduling, proof-of-play reports and billing
- Multi-language content, including right-to-left scripts like Arabic
Can Sigosoft deliver signage software to other countries?
Yes. We’ve delivered projects for clients in more than 40 countries, including the USA, Europe, the Middle East and Africa. For signage, we build, deploy and support the software remotely, while hardware purchase and on-site installation are handled by the client or their local installer. You don’t pay for engineers to fly in to mount a TV, and your local installer knows the venues better than we would.

What about privacy on token screens?
A waiting-room screen is a public display. Showing a patient’s full name next to a doctor’s specialty can reveal health information to everyone in the room, so the safer default is token numbers, not names. The rules depend on where you operate: HIPAA in the US, UK GDPR in Britain, the Digital Personal Data Protection Act, 2023 in India, and personal data protection laws in the UAE and Saudi Arabia. This isn’t legal advice; confirm what your screens can display with a lawyer in your jurisdiction.
Common mistakes in digital signage projects
Using consumer TVs without checking power settings.
Many home TVs don’t turn back on after a power cut, and the app won’t restart unless it’s set to launch on boot.
Assuming the internet will always be there.
If the player streams everything live, the screen goes blank when connectivity drops. Store content on the device.
No remote monitoring.
Without a heartbeat from each screen, the first person to notice a dead screen is usually the advertiser who paid for it.
Showing personal data on public screens.
Token numbers are enough.
Ignoring placement.
A normal TV facing a sunlit shop window is unreadable at noon.
No plan for content.
Decide who owns content updates before launch, or screens end up showing last year’s offer.
FAQ
What is cloud digital signage software?
A system for managing content on many screens from one online dashboard. Content is scheduled in the cloud and played by an app on each screen, which stores it locally and keeps playing if the internet drops.
How much does digital signage software development cost?
At Sigosoft, a custom build starts at $5,000, with hosting billed separately. Cost rises with platforms, real-time features, integrations and advertising features.
Does digital signage work without the internet?
It should. A well-built player stores its playlist locally, keeps playing offline and syncs when the connection returns. Real-time features like token calling need a connection to receive new calls.
Which devices can run a signage TV app?
Android TV boxes and Android-based smart TVs are the most common and affordable. Fire TV devices, other smart TV platforms and dedicated players can also be supported, depending on requirements.
Can one dashboard manage screens in several countries?
Yes. Screens can be grouped by country, city or client, with schedules set in local time.
Can token calling include a voice announcement?
Yes. Our Medicino TV app announces each token by voice as well as showing it on screen.
Can I rebrand a signage platform as my own?
Yes. We build custom platforms that clients own and brand, which suits resellers and integrators.
Does Sigosoft install the screens?
No. We handle the software remotely. Your team or a local installer handles hardware and installation.
