Solid architecture, clean code and on-time releases. A real tech partner.
Mobile App Development Company in Bangladesh apps people keep using.
Most apps get deleted within days. Digiil is the mobile app development company in Bangladesh that builds fast, simple, reliable iOS and Android apps designed to earn a place on the home screen.
Mobile app development is the process of designing, building, testing and launching apps for iPhone (iOS) and Android devices. Apps can be built natively for each platform, or with cross-platform frameworks like Flutter and React Native that share one codebase. A good mobile app is fast, simple, works on slow networks, is tested on real devices and is launched with proper store listings.
The right approach for your app.
| Cross-platform (Flutter / React Native) | Native (Swift / Kotlin) | |
|---|---|---|
| Codebase | One for iOS and Android | Two separate apps |
| Cost and time | Lower, faster | Higher |
| Performance | Great for most apps | Best for heavy graphics or hardware |
| Best for | Most business and consumer apps | Games, AR, deep device features |

The problem
PayNest's first app was slow, crashed on older Android phones and had a 2.9-star rating. Users complained about failed payments on weak mobile data.
What we did
- 01
Rebuilt the app in Flutter with a redesigned, simpler flow.
- 02
Optimized for low-end Android phones and weak networks with retries and offline states.
- 03
Added biometric login and clear payment status screens.
- 04
Set up crash monitoring and staged rollouts for each release.

Built for businesses like yours.

A fintech app had a 2.9-star rating. Reviews all said the same thing: slow, crashes, payments fail on mobile data. The features were fine. The experience was not. After a rebuild focused on speed and reliability, the rating climbed to 4.7.
That is what users care about. As a mobile app development company in Bangladesh, Digiil builds iOS and Android apps that are fast, simple and dependable, even on a budget phone with weak signal.
Native vs. cross-platform
Cross-platform frameworks like Flutter and React Native let one codebase run on both iOS and Android. For most business and consumer apps, they save time and money with great performance. Native development with Swift and Kotlin is best when you need heavy graphics, advanced camera or AR features, or deep hardware access.
Building for Bangladesh
Apps for local users need extra care:
- Low-end Android phones are common, so we test on them.
- Mobile data can be slow or patchy, so apps must handle retries and offline states.
- Bangla support in text, numbers and fonts.
- Local payments like bKash and Nagad.
- Small app size, since storage is often tight.
Designing apps people keep
- Get users to the main value in the first minute.
- Ask for permissions only when needed, with a reason.
- Keep the main actions one or two taps away.
- Use push notifications that help, not spam.
- Fix crashes fast with monitoring.
Launching on the stores
Both Apple and Google review apps before they go live. We prepare store listings, screenshots, privacy details and test accounts, so approval goes smoothly. We also plan app store optimization, so people can find your app in search.
After launch
New phones and OS updates arrive every year. We provide updates, monitoring and new features. For apps with a web side, see our web app development service, and for design-first work, our UI/UX team.
- Cross-platform suits most apps. Native suits heavy or hardware-based apps.
- Design and test for low-end phones and weak networks.
- Show value fast and keep main actions close.
- Prepare store listings early for smooth approval.
- Monitor crashes and keep updating after launch.

How much does it cost to build a mobile app in Bangladesh?
It depends on features, design, platforms and backend needs. A focused MVP costs much less than a full-featured app. We give an itemized estimate after discovery.
Should I build with Flutter or native?
Flutter or React Native suits most business and consumer apps and saves time. Native is better for heavy graphics, AR or deep hardware features.
How long does it take to build a mobile app?
A simple MVP often takes 8 to 12 weeks. Larger apps take 4 to 8 months and are built in phases.
Do you publish the app on the App Store and Google Play?
Yes. We prepare the listings and handle submission and the review process for both stores.
Can you integrate bKash and Nagad?
Yes. We integrate local payment methods like bKash and Nagad, as well as cards and other gateways.
Do you maintain the app after launch?
Yes. We offer monitoring, bug fixes, OS updates and new features.
