“We need an app” — I hear this regularly. But when we start breaking down the task, it turns out that everyone understands something different by “app”: a mobile app in the App Store, a client personal account, a booking system, a catalog showcase. And there are also Telegram Mini Apps, PWAs, and just a good bot.

Let's figure out when which option is suitable and what the cost depends on.

⚡️ Three options — three logics

📱 Mobile app (iOS / Android) — the most expensive and longest path. Two platforms, store moderation, constant updates for new OS versions. The price range on the market is huge: from hundreds of thousands for a freelancer to several million in a studio. What you pay more for — architecture, integrations, support, and responsibility. What you pay less for — often technical debt that will catch up later.

💬 Telegram Mini App — a full-fledged web interface inside the messenger. Not a bot with buttons, but showcases, personal accounts, forms, catalogs. Cheaper than a mobile app, but not as cheap as many think: as soon as integrations with CRM, 1C, payment systems are added, the budget grows significantly.

🌐 PWA (Progressive Web App) — an intermediate option that is rarely talked about. Works in the browser, installs on the desktop without a store. Does not have full access to device functions, but for many tasks it is the optimal choice.

💰 What really affects the cost

Not the technology, but the complexity of the task.
The same “client personal account” can cost 10 times differently depending on:
→ Number of roles. Client, manager, administrator — each role is a separate logic and interface.
→ Integrations. Connecting to CRM, 1C, payment system, calendar — each integration is time and money.
→ Scenarios. “Book an appointment” — simple. “Book, get a reminder, reschedule, cancel, leave a review, get a bonus” — much more complex.
→ Who does it. Freelancer, small team, studio — the price difference can be 5–10 times. But also in what you get as a result.

✅ When Telegram Mini App is the right choice
→ Your audience is already on Telegram — no need to force the client to download something new.
→ The task is communication + service: booking, order statuses, catalog, notifications.
→ Speed of launch is important. One codebase, no store moderation, instant updates.
→ Push notifications via Telegram are free and do not end up in spam filters.

📱 When a mobile app is better
→ The app is your product itself, not a communication channel.
→ Offline mode, deep-level work with camera, GPS, device sensors are needed.
→ The audience uses the product daily for 20+ minutes.
→ Tens of thousands of active users and complex UX with many screens.

⚠️ The main mistake
Choosing a technology before the task is formulated. “We need a bot” or “we need an app” is not a task. The task is “we lose 30% of bookings because clients don't follow through” or “managers spend 3 hours a day manually transferring data from chat to CRM.”

When the task is clear, the choice of technology becomes obvious. And sometimes it turns out that what is needed is not development, but putting processes in order.
