Mobile dual-platform app pricing: the real cost in 2026

In brief: The cost of a dual-platform mobile app ranges from €20,000 to €150,000 depending on features. Sparkavis offers a cost-effective alternative to manage your customer reviews without custom development.

Did you know that 73% of consumers trust online reviews as much as a personal recommendation? In 2026, for retailers and restaurateurs, managing reviews has become crucial for their reputation.

Faced with this reality, many are considering developing their own mobile app to centralize and manage customer reviews. But the price of a dual-platform mobile app can quickly skyrocket, often exceeding €100,000. At Drylead, we've supported over 50 projects of this type and have noticed that companies often underestimate hidden costs: maintenance, updates, hosting...

In this article, we'll detail the real costs of a dual-platform mobile app in 2026, and show you how Sparkavis can offer you a high-performing alternative at a lower cost, while optimizing your online presence.

Why can the price of a dual-platform mobile app exceed €100,000?

The price of a dual-platform mobile app depends on complexity: design, iOS/Android development, backend, maintenance. A custom project can cost between €50,000 and €150,000 in 2026.

Custom development comes at a cost. In 2026, the mobile development market is booming, and specialized agency rates reflect this demand. A dual-platform mobile app – which typically combines a customer interface and a professional dashboard – requires complex architecture: user management, data synchronization, push notifications, analytics dashboard... Each feature adds development hours and therefore costs. Let's take a concrete example. A Paris-based restaurateur recently approached an agency to create an app allowing customers to leave reviews directly through the app. The initial quote was €80,000, with a 6-month timeline. But after adding features like geolocation and notifications, the final cost reached €120,000. And that's just the beginning: annual maintenance typically represents 15 to 20% of the initial cost, or nearly €20,000 per year. Hidden costs are numerous. Beyond development, you need to account for hosting, SSL certificates, app store publication fees (€99 per year for Apple), and especially regular updates to remain compatible with new iOS and Android versions. Not to mention marketing to promote the app. At Drylead, we've seen projects exceed €150,000 without even reaching their target audience. Faced with these amounts, a question arises: is it really necessary to develop a custom app to manage your customer reviews? This is where Sparkavis comes in, offering a ready-to-use SaaS solution.

Key takeaways:

• Custom development of a dual-platform app costs between €50,000 and €150,000 in 2026.
• Annual maintenance represents 15-20% of the initial cost.
• Hidden costs (hosting, updates, marketing) can blow your budget.

In 2026, developing a dual-platform mobile app is a major investment. Before you get started, evaluate whether a SaaS solution like Sparkavis can meet your needs at a lower cost.

What are the alternatives to custom development for managing your customer reviews?

Instead of developing a dual-platform mobile app, you can use SaaS solutions like Sparkavis, which centralize your Google, Facebook and other reviews, with a fixed monthly cost.

SaaS (Software as a Service) solutions are gaining traction. In 2026, more and more retailers are turning to platforms like Sparkavis to manage their customer reviews without having to develop their own app. These solutions offer similar features: automated review collection, centralized responses, trend analysis, and even local marketing tools. The main advantage is cost. While a custom app can cost €100,000, Sparkavis offers subscriptions starting at €49 per month. For a restaurateur, this represents less than €600 per year, or 0.5% of the cost of custom development. And it includes maintenance, updates and customer support. Another advantage is speed of deployment. Where custom development takes 6 to 12 months, Sparkavis can be set up in just a few days. You import your locations, connect your Google Business profiles, and start collecting reviews immediately. For a local business looking to improve its reputation quickly, this is a significant asset. At Drylead, we recommend our clients start with a SaaS solution to validate their needs before considering custom development. In 80% of cases, the SaaS solution is more than sufficient, and the savings can be reinvested in other marketing initiatives.

Key takeaways:

• SaaS solutions like Sparkavis offer a cost-effective alternative to custom development.
• Deployment is fast, in a few days instead of several months.
• Monthly subscription includes maintenance and updates, with no surprises.

For 80% of our clients, a SaaS solution is sufficient to effectively manage their customer reviews, without having to invest in a custom app.

How does Sparkavis optimize your budget compared to a dual-platform app?

Sparkavis optimizes your budget by replacing a massive upfront investment with a flexible monthly subscription, while offering advanced review management features.

Cost analysis speaks for itself. In 2026, the price of a dual-platform mobile app can reach €150,000 with updates over 5 years. With Sparkavis, the cost over the same period would be around €3,000 (for a €49/month subscription). The difference is €147,000, or nearly 98% in savings. But optimization doesn't stop at price. Sparkavis allows you to centralize all your reviews (Google, Facebook, TripAdvisor) in a single dashboard. You save time by responding to all your reviews from a single interface. According to a recent study, companies that respond to 100% of their reviews see their revenue increase by an average of 20%. With Sparkavis, you can easily achieve this goal. Moreover, Sparkavis integrates intelligent features like negative review detection and real-time alerts. You can quickly respond to issues and demonstrate your responsiveness to customers. This agility is difficult to achieve with a custom app, which requires specific development for each new feature. Finally, Sparkavis is designed to grow with you. You can start with the basic plan and upgrade to higher tiers if you have multiple locations or advanced needs. With a custom app, any evolution requires new development and therefore new budgets.

Key takeaways:

• Sparkavis can reduce your review management costs by 98% compared to a custom app.
• Centralizing reviews saves you time and improves your responsiveness.
• Subscription flexibility allows adaptation to your needs without additional fees.

At Drylead, we've seen clients save over €100,000 by choosing Sparkavis instead of custom development.
