Apptunix Reviews & Testimonials
Numaan Shaikh CRM Product Owner at Trafalgar Luxury Group
4.8★
Mobile App Development Review from Numaan Shaikh
I had an excellent experience working with Apptunix. Their team was professional, responsive, and delivered a high-quality app that met all our requirements. They were great at understanding our vision and transforming it into a user-friendly, functional product. Communication was seamless throughout the process, and they provided valuable insights that improved the overall design. Highly recommend them for anyone looking to develop an innovative and reliable mobile app!
Tim Nguyen CEO at PayX

Mobile App Development Review from Tim Nguyen
Warning: Avoid Apptunix (apptunix.com) If you're considering hiring offshore developers, especially from India, I want to share a warning about Apptunix (apptunix.com) and its CEO. My company worked with them on a development project, investing close to $40K, only to have them hold our code hostage and demand more money before releasing it.We entered into the project with clear expectations and milestones, but as we progressed, Apptunix consistently delayed, under-delivered, and eventually refused to hand over the work we had already paid for unless we agreed to pay more. This kind of behavior is nothing short of extortion. It seems like their CEO and leadership are more interested in squeezing money out of clients than delivering quality work.Beyond the financial frustration, the skill level and talent from this team were not up to par. The development work was substandard, full of bugs, and lacked the quality we expected for the investment we made. I strongly urge anyone considering offshore development to do your due diligence or, better yet, reconsider offshore development altogether, as the experience in some regions, particularly India, seems to be in decline.
Will Thomas Head of Product Design at Birdie

Mobile App Development Review from Will Thomas
We were creating a software in the health care environment. It was a software for publishers to improve their revenue by making a dynamic inventory on their side and getting more income out of their advertising. We needed help with the recruitment of an outsourced, part-time frontend developer with broad experience and availability.

AJ Canty CTO and Co-Founder at Primer
5.0★
Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

Reviews verified by DesignRush and sourced from the agency's profile View All Reviews
Smart contract development and auditing: Writing self-executing code and reviewing it to prevent bugs, exploits, or costly failures Â
dApp development: Building decentralized apps that run on blockchain networks instead of centralized servers Â
Token development and NFT platforms: Creating digital tokens, cryptocurrencies, and marketplaces for trading assets Â

What platforms do blockchain developers use?
Blockchain development firms use a mix of public networks, enterprise platforms, and developer tools to build, deploy, and manage blockchain solutions. They choose platforms based on speed, cost, scalability, and whether the project needs a public or private network.Â
Key platforms and networks:Â
Ethereum: The most widely used platform for smart contracts and decentralized applications Â
Solana: Built for high speed and low fees, often used for scalable dApps and marketplaces Â
Avalanche: A flexible platform that supports custom blockchain networks and fast transaction finality Â
Hyperledger Fabric: Designed for private, permissioned systems used by enterprises Â
Corda (R3): Common in finance and regulated industries where data privacy is critical Â
IBM Blockchain: Enterprise-grade solution built on Hyperledger for secure business use cases Â
Development tools and infrastructure that blockchain development agencies use:Â
Node providers (e.g., Alchemy, Infura, QuickNode): Give developers access to blockchain networks without running their own nodes Â
Smart contract tools (e.g., Remix IDE): Used to write, test, and deploy contract code Â
Frameworks and CLIs (e.g., Ignite CLI): Help set up and manage blockchain projects fasterÂ
How much do blockchain companies charge for their services?
Simple solutions: 1 to 2 months Basic wallets or simple smart contract apps Â
Mid-level projects: 2 to 4 months dApps with integrations and user functionality Â
Complex systems: 4 to 9+ months DeFi platforms, marketplaces, or enterprise solutions Â
Blockchain development agencies build products in stages, and each is adding time:Â
Planning and requirements: 1 to 2 weeks Â
Architecture and design: 2 to 4 weeks Â
Development: 1 to 6 months Â
Testing and QA: 2 to 4 weeks Â
Deployment: 1 to 2 weeksÂ
Factors that affect the timeline include scope and feature set, choice of blockchain platform, team experience, and whether you build from scratch or use existing tools.
What is the difference between public and private blockchains?
Public blockchains are open to anyone, while private blockchains are restricted to approved users and controlled by an organization.Â
You can see the main differences in the following table:Â
Feature
Public blockchain
Private blockchain

Controlled by one entity or group

How do blockchain development agencies ensure security?
Blockchain development firms ensure security by combining secure coding, testing, and continuous monitoring to prevent vulnerabilities and protect data and transactions.Â
Key security practices include:Â
Smart contract audits: Reviewing code to detect bugs, exploits, and logic flaws before deployment Â
Secure development practices: Using proven frameworks, code standards, and peer reviews Â
Encryption and key management: Protecting data with cryptography and secure storage of private keys Â
Testing and simulation: Running stress tests and attack scenarios to identify weaknesses Â
Access control: Limiting permissions and enforcing authentication for users and systems Â
Ongoing monitoring: Tracking activity, detecting threats, and applying updates or patches quickly Â
Security is built into every stage, not added after deployment.Â
