By Gaurav Parvadiya | Last Updated On January 4th, 2026
Convert Base44 App to Mobile App if you want users to actually show up every day. Web apps are forgettable. Mobile apps live on the home screen, send push notifications, and drive real engagement. If retention matters, mobile isn’t optional—it’s the next step.
SaaS founders can take advantage of an innovative service called Base44. Simply type in a diffused English description of your customer portal, CRM, or back-office tool, and Base44 will generate a working web application for you within minutes. You can leave the rest of the work, such as web app authentication, databases, and email flows containing your Stripe payment workflows to Base44 and you can focus your attention on something else. Coding is not required.
Wix, who recently purchased Base44 for $80 million, and his team have helped over 250,000 users build web apps, from simple task managers to complex business automation tools. MVPs are being launched by new startups within a few hours, and non-technical founders pair expensive subscriptions to SaaS software with new tailored applications designed for manual workflows.
The reality is a web app is only, and will only ever be, a starting point. You Base44 accounts may have a powerful CRM. You may have designed a beautiful customer portal. You may have solved a problem with your internal dashboard, but the moment any of your users have to remember to open their browser, type in the URL, and log in, you lose. My friends, you will have to fix your software.
Most smartphone users spend an average of 4 hours on mobile apps and 30 minutes on mobile browsers. For SaaS products that need daily interaction like CRMs, project managers, client portals, productivity tools, etc, that gap is not just a small inconvenience. It’s the line drawn between an active user base and a churned subscription.
Base44 is an AI-powered, no-code platform that generates complete web applications from natural language descriptions. In contrast to other tools that let you build by dragging and dropping, Base44 comprehensively interprets what you need and generates all of the necessary components, including the user interface, database, authentication system, business logic, and hosting.
What makes Base44 ideal for SaaS applications:
Base44 shines when it comes to the tools that enable all other modern applications: CRMs, customer portals, admin dashboards, project management, inventory management, HR tool, client dashboards and every other tool to manage your business.
The downside? Base44 is great at creating web applications. web applications, even great ones, need to be the bottom of the funnel in a mobile first world.
For consumer apps, mobile is obvious. For B2B SaaS, customer portals, and intetnal tools, the case is just as compelling, just not talked about as much.
Unlike emails, clients can receive prompt notifications on their phones, which have much higher engagement rates. Emails have a 20% engagement rate, while notifications have a higher engagement rate of about 90%. prompt notifications can remind clients of important deadlines that need to be completed. Emails that say, “You have 3 follow-ups that are due today” will likely go unengaged in an inbox; meanwhile, prompt notifications that say “3 follow-ups due today” will receive immediate engagement. If a task management SaaS product expects clients to manage their follow-ups and tasks, notifications are a critical to success.
When a customer portal is housed in a internet browser, users are likely to interact with it only when it is intentionally remembered. But when the portal is hosted on their device’s home screen, it becomes a seamless addition to their daily workflow. Apps feel like tools, and websites feel like destinations. Websites are visited much less often than tools.
Your field sales team needs offline CRM access during times of spotty service like in basements or on airplanes. Your warehouse staff needs offline access to inventory data during times when WiFi isn’t available.
Unlike web apps, which display loading spinners and frustrate users, native apps can cache data and work offline.
If your client accesses your customer portal, do they see a web browser URL window, or do they see your app’s icon? For B2B SaaS products, having an App Store presence, in all its glory, signifies maturity and appreciation that web browser-based tools seldom do.
Mobile app users engage 3-5x more than web users. For subscription SaaS products, that engagement correlates to retention which is the determining factor for revenue, net lifetime value, and word-of-mouth growth.
Here’s the insight modern SaaS founders have with the build-to-mobile pipeline:
Not just any website wrapper, Twinr, is a retention-led mobile platform made uniquely for SaaS products’ difficult challenges.
Your Base44 app operates in Twinr’s native container. Yet, you also have the option to build customized native screens for vital tasks, like onboarding, upgrade asks, feature promotion, and quick dashboards. Screens built for mobile load and convert better.
What users are entering the app and when? Twinr AI analyzes behavior and assists in the timing of push notifications. Where is the feature adoption opportunity? You are the focused one.
No per message fees, no third party services like One Signal to manually configure. Onboarding, activity reminders, feature announcements, re-engagement. All yours.
What are the important metrics for subscription products? Daily users, session frequency, retention over time, engagement. Track that to understand the behavior of your mobile users. It is all in one dashboard.
The Twinr staff provides the necessary help for submission of apps to launch the app, and creates playbooks for launching, and customer success managers are tasked to each unique customer. For SaaS founders who like to concentrate on their product instead of the app store guidelines, this saves a lot of work.
If you change the Base44 web app, you change the mobile app instantaneously. No rebuilding. No resubmission. Your products on web and mobile are always in sync.
Want to expand your Base44 SaaS App to mobile? Here are the main steps:
In order to transform your app to mobile, you need to do the following steps:
In Twinr’s visual app builder, you can set up:
Here is where the SaaS-specific approach is key:
Notifications that a task is due for CRM and project management applications
Tools for scheduling have appointment reminders
Analytics dashboards notify users when reports are ready
Gentle nudges that suggest the user has not logged in within the week
Announcements for new features
Celebrations when users reach new levels in their activity
In-app comparisons for different plans available
Notifications for limited-time offers
Notifications for reaching feature limits that suggest an upgrade
To test the mobile experience on a real device, download Twinr’s preview application and walk through:
Flows for login and authentication, Navigation through a core feature, Delivery of push notifications, Performance of a native screen and behavior when the device is offline
Pick one of the following to do:
Put app install banners on the Base44 web app to encourage mobile downloads, use smart links in emails and communications that open the mobile app, and promote app-only or early access features to encourage downloads and use retention analytics to locate points of drop-off and potential improvement.
Web: Clients do not check for updates and support tickets pile up Mobile: Users receive push notifications when they receive new messages, documents are uploaded, or the status changes on tickets. Users check the app daily instead of on a weekly basis.
Web: Sales reps regularly forget to update records during the day Mobile: Users can quickly capture native screens for on-the-go updates and receive push reminders for follow-ups. Field teams update records in real-time.
Web: Task deadlines slip because users do not check dashboards Mobile: Users receive notifications for tasks due directly to their lock screens. Completion rates increase dramatically.
Web: Executives check metrics irregularly and the issues get caught late Mobile: Executives receive Daily Summary pushes with key metrics. Threshold alerts when key metrics spike or drop.
Web: No shows as clients forget about their appointments.
Mobile: Reminder sequences. One-tap confirmation and rescheduling via push notifications.
Absolutely! All Base44 applications with active links can be converted. This can be anything from CRMs and customer portals to internal tools, dashboards, and other web apps you’ve developed. Everything from Base44’s built-in authentication, user roles, and database can be carried over without issue.
Not at all. Your mobile app shares the same authentication as your Base44 web app. Your users will be able to log in with the same credentials, and their information, along with their permissions and settings, will be automatically synchronized.
Twinr can send user-relevant push notifications. You can customize them based on user activity, roles, or groups. For example, you can alert users when you assign them tasks and send system event notifications to admins only.Can I Have Different Features for Mobile vs Web?
Sure thing! Your main Base44 app will remain synced in real time, while you will also be able to customize mobile exclusive native screens in Twinr. For streamlined mobile workflows, quick-action dashboards, and other premium features that justify app downloads, this is how SaaS founders typically approach mobile applications.
Changes happen by magic! No, really. When you update your Base44 app, all users will immediately see their changes in the mobile app. No need to do any rebuilding, app store resubmissions or any of the other time-consuming processes that other SaaS products need to go through if they are continuously shipping features.
Most converters simply wrap your website in an app. Twinr is focused on customer retention. Because of this, we do things the other converters cannot do, and in very SaaS-specific ways. For example, we give you unlimited notifications at no extra cost and native screens that go beyond WebView. If your app needs user engagement and retention, Twinr is the infrastructure you need.
