In 2025, a Belgian spends an average of 3h47 per day on their smartphone. Video accounts for 82% of internet traffic. If your brand is not present on mobile screens and in video formats, you are missing the majority of your potential audience.
At Ligne 1, we develop complete digital solutions to meet your customers where they are: high-performance mobile applications (native, cross-platform or PWA), targeted digital media campaigns and video/motion design content that captures attention in seconds.

Mobile applications: your brand in your customers' pocket
A mobile application is no longer reserved for tech giants. More and more Belgian SMEs are investing in apps to improve the customer experience, build audience loyalty and create new revenue channels. The question is no longer "do I need an app?" but "what type of app suits me best?".

Our mobile expertise
- Needs analysis — Before writing any code, we determine together whether a native, cross-platform (React Native, Flutter) or PWA app is the best choice for your project, budget and audience. No predefined solution: technology serves strategy, never the other way around.

- Agile development — Iterative development in 2-week sprints with regular demos. You see and test the app as it is built — no surprises at delivery.
- Publication & ASO — We manage the entire publication process on the App Store and Google Play Store: optimised screenshots, ASO (App Store Optimisation) descriptions, review and update management.
- Maintenance & evolution — Crash monitoring, usage analytics (Firebase Analytics), security updates and new feature development over time.
Cross-device, installable, offline-first. Cost-effective and high-performance solution.
React Native or Flutter. One codebase for both iOS and Android.
Maximum performance. Separate development for each platform.
Digital Media Plans: invest your ad budget where it pays off
A digital media plan is the strategic roadmap that defines where, when, how and how much you invest in online advertising. Without a media plan, you spend blindly. With a well-designed media plan, every euro invested generates a measurable return.
The platforms we master
- Google Ads (Search & Display) — Text ads in Google search results and graphic banners on the partner site network. The king channel for capturing prospects in the buying phase: "I'm looking for a plumber in Liège right now."
- Meta Ads (Facebook & Instagram) — Visual campaigns targeted by interests, behaviour and demographics. Ideal for B2C, brand awareness and lookalike audiences based on your existing customers.
- LinkedIn Ads — The premium channel for B2B. Targeting by job title, industry, company size and seniority. Perfect for B2B lead generation and recruitment.
- YouTube Ads — Pre-roll, mid-roll and bumper video ads. The video format increases brand recall by 80% compared to static formats.
- TikTok Ads — For brands targeting 18–35 year-olds, TikTok has become essential. Creative content, Spark Ads (boosting organic content) and brand takeovers for maximum impact.
- Programmatic (Display & Video) — Automated real-time purchase of advertising space on thousands of websites. Ultra-precise targeting based on user behavioural data.
Our media methodology
- Objective and KPI definition — Awareness (impressions, reach) vs conversion (leads, sales, ROAS). Each objective dictates the choice of platforms, formats and budget.
- Optimal media mix — Intelligent budget allocation across different channels according to the marketing funnel stage (awareness → consideration → conversion → retention).
- Creation of advertising assets — Visuals, videos, copy and landing pages adapted for each format and each platform. Systematic A/B testing.
- Real-time tracking & optimisation — Daily performance monitoring with bid, audience and creative adjustments. We continuously reallocate budget towards the best-performing campaigns.
Our average ROAS (Return on Ad Spend) is 4.2x — for every euro invested in advertising, our clients generate €4.20 in revenue. Let's talk about your media budget →
Motion design & video: capture attention in 3 seconds
In a world where the average attention span is 8 seconds, video and motion design are the only formats capable of captivating, informing and convincing simultaneously. Web pages containing a video convert 80% better than those without one. Video posts on social media generate 1,200% more shares than text and images combined.

- Motion design (2D animation) — Animated explainer videos that transform complex concepts into simple, engaging visual narratives. Perfect for B2B services, technical processes and tutorials.
- Social media videos — Short video content (15 to 60 seconds) optimised for each platform: Instagram Reels, Stories, TikTok, LinkedIn Video, YouTube Shorts. Vertical 9:16 format, integrated subtitles, visual hooks in 3 seconds.

Companies that integrate video into their marketing strategy report an average 49% increase in revenue compared to those that don't (source: Aberdeen Group). Video is not a luxury — it is a growth accelerator.
Multi-screen strategy: a consistent presence everywhere
Your customers navigate between 3 to 5 screens per day: smartphone, computer, tablet, connected TV, smartwatch. Your brand must deliver a consistent and seamless experience regardless of the device used — this is the principle of multi-screen (or omnichannel) design.
At Ligne 1, we design digital ecosystems that work harmoniously together:
- Responsive website — Automatically adapted to all screen sizes (mobile, tablet, desktop, ultra-wide). Mobile-first design with breakpoints tested on 15+ devices.
- Mobile application (native or PWA) — When an app is relevant, it is designed to complement the website (not replace it). Data and account synchronisation between web and mobile.
- Responsive email marketing — Email templates optimised for every email client (Gmail, Outlook, Apple Mail, Yahoo) and every device. Correct rendering across all media.
- Adapted social media content — Adaptation of your visuals and videos for each format on each platform: square for the Instagram feed, vertical for Stories/Reels, horizontal for YouTube and LinkedIn.
- Global visual consistency — A unified design system that guarantees your brand is immediately recognisable, whether displayed on an iPhone SE or a 32-inch monitor.
Your questions about media & applications
How much does a mobile application cost in Belgium?
A professional mobile application costs between €10,000 and €50,000 depending on complexity (number of features, design, integrations). PWAs (Progressive Web Apps) are a more affordable alternative from €5,000 and work on all devices without installation from a store.
What is the difference between a native app and a PWA?
A native app is developed specifically for iOS or Android, downloadable from the App Store or Play Store. It offers maximum performance and full hardware access. A PWA is an enhanced website that behaves like an app (installable, usable offline) — much less expensive and simpler to maintain.
How long does it take to create a motion design video?
A motion design video of 60 to 90 seconds takes an average of 3 to 5 weeks of production: 1 week for brief and storyboard, 2 to 3 weeks of animation, 1 week of post-production and corrections. Timelines can be shortened depending on project urgency.
Do you manage advertising campaigns on social media?
Yes. We design and manage campaigns on Google Ads, Meta (Facebook/Instagram), LinkedIn, YouTube and TikTok. From media planning to creating visuals and videos, through to daily performance optimisation — we manage the entire process to maximise your ROAS.
Does video help SEO?
Absolutely. Pages containing a video are 53 times more likely to appear on the first page of Google (source: Forrester Research). Video also increases time on page and reduces bounce rate — two positive signals for your SEO ranking.
Do you offer a complete app + video + media package?
Yes. Our offerings are 100% modular but we offer "digital launch" packages that combine app (or PWA), presentation video and launch advertising campaign. The package is more financially advantageous and guarantees total consistency across all media.
Your brand deserves to be everywhere.
