Programming › What Mobile App Should I Build Next? by davidaluu(op): 12:22pm On Mar 29
I've gotten good at mobile app development recently and I use my own apps personally on my phone, it's quite cool and surreal actually knowing I could even build a functional mobile app, like a superpower even 😄. But I've hit a roadblock, i have no inspiration whatsoever on what to build next? Maybe I should go back to unity 3d and crank up a game? Any suggestions? Collabs and email is open to all. What app do you think should exist?

Mobile apps have higher retention so that matters as well
as69:
Mostly been on the web side — easier to deploy, no app store gatekeeping. But the point about scarcity driving demand is real. Less supply, more leverage for mobile specialists.

Tried Expo/React Native recently and the DX is genuinely better now. For simple apps you can ship cross-platform without much compromise. For complex native features you still need to go full kotlin or swift sha.

Stephen0mozzy's point about PWAs is valid too — if your product doesn't need biometrics or local file access, a well-optimised web app covers most use cases without asking users to install anything.
Programming › Re: Any Mobile Devs Here? Why So Rare? by davidaluu(op): 5:16pm On Mar 28
The browsers you use e.g chrome, aren't they mobile apps? Or would you prefer WhatsApp over the web than on phone natively?
Stephen0mozzy:
Smart phone users have browsers on their phones. Unless for critical applications like banking and Identity, most people still prefer the web app variant than installing a new app - i still read reddit on web, see our dear nairaland 😁
Programming › Re: Any Mobile Devs Here? Why So Rare? by davidaluu(op): 3:36pm On Mar 28
Except for saas and certain startups yes but you have to remember does account for a fraction of the current landscape. They are more smartphone users than computer users which are predominantly web oriented.
Stephen0mozzy:
Not all software products requires mobile platform-specific features - so "mobile is the future" is an hasty conclusion - most internal business applications run locally too, either as desktop apps or on local intranet - web app.

Mobile-first and native-first is not the same; and there are many reasons why a new SaaS product will prefer to LAUNCH first on web over mobile - web apps are bastardly efficient these days too, and don't need platform gatekeeping - so most products that don't really need native features - local file system access, biometrics, precise location, etc - will still go for web.

Web apps also implement mobile-first - mobile first just means the user interface properly adapted for mobile screens.

But of course, mobile skills are quite future proof and mostly because its lot more harder to publish a mobile app than it os to deploy a web app - so people who have experience publishing apps will still have their place.

On the Developers side
There are fewer mobile devs, because the environment setup/requirements is much more higher - i.e no way you're building an ios app without Xcode and Mac and iphone. On windows (before Expo) you need to have android studio installed even to locally build react native apps
Programming › Re: Any Mobile Devs Here? Why So Rare? by davidaluu(op): 3:34pm On Mar 28
Mobile app would always offer a better user experience. Most trillion dollar companies traffic comes now from apps as opposed to back then in the early 2000s. Mobile should always be a top priority in your business plan. Think about it, it's faster and convenient to use a bank app than it is to log on to their website for the same purpose
Alphabyte3:
It is better to build both because we have billions of android and iOS devices. Most prefer mobile while some prefer web . One big problem of Nigerian developers org they hardly upgrade their software every 3-4 months because of cost .
Programming › Re: Any Mobile Devs Here? Why So Rare? by davidaluu(op): 3:31pm On Mar 28
exactly, mobile apps is how we know mostly interact, we even have to use browsers apps before we access the web even. I think that's why we can command more honestly
platymus:
I love your observation! I have been doing (web) fullstack and still doing it. In recent years I noticed that mobile is the true future so switched and started with reactnative and dart/flutter. I recently built 3 edtech products (2 with reactnative and 1 with flutter) which will be launch soon in the market by the product owners. I noticed that users are mobile first before ever trying to use their laptops. They buy, watch,read and do many things from their device.Also mobile device have been given more computing power now than ever before. Many developers will have to switch to mobile if they ever want to to make meaningful impact in their career It is an addition to their existing skill set not deduction!
Programming › Re: Any Mobile Devs Here? Why So Rare? by davidaluu(op): 3:29pm On Mar 28
That's the thing. It's very scarce even globally. But I mean that means increased demand for us.
Alphabyte3:
We have 100 web jobs over 1 Mobile jobs based on recent findings. We have dart(flutter), swift , java and koltin dev but they hardly comments they all gone silent.
Programming › Any Mobile Devs Here? Why So Rare? by davidaluu(op): 12:30pm On Mar 28
It seems everywhere are web devs but very little devs for mobile app development. Isn't there any mobile app developer on here? Why is that?
My stack is swift for iOS and kotlin for android. I use both xcode and android studio for both. Still haven't gotten used to the cross dev frameworks yet although I do know a bit of flutter with dart. Recent build was an AI chatbot app. Built an external server for the backend. Share yours below.

Working on the upload but I don't think I'm including ads for now. let's see how it goes first
Alphabyte3:
Nice one when are you uploading to app store and add a custom ad network instead of Google ads because of the current strict policies on Africans like OpenAI.

Ads. Js ,Tracking.Js,adspanel, deleteads , uploadads adsprofile , blockads . Adsfees sidebar, rightbar.

I'm still working on Google's playstore approval. I just recently applied. But I can assure you it's safe. I just had to put it on drive to share for some colleagues
MindHacker9009:
I would avoid downloading any app not on Google or apple app store for security reasons. Only if the app is open source then maybe download directly but still be careful.

Tech Jobs › Create An AI Solution/software For Your Business by davidaluu(op): 4:52pm On Mar 22
AI when combined with tools and workflows becomes agentic and more capable. It excels in cognitive and repetitive tasks where humans fall short. Anything that lives on the computer or that can be transmitted via the internet can be delegated for AI to handle leaving business owners more time on hand for tasks that truly matter. I'm David, an AI engineer with experience in AI since 2022. Reach out to my email at davidaluu1@gmail.com and let's book a call to discuss how we can develop an AI software to transform and automate your business. The industry is fast changing but the ones who will still remain are the ones that learn to harness AI not fear it.

Programming › Re: Try Out This Legal AI Expert I Built For Free by davidaluu(op): 7:51pm On Feb 25
Common law yes. Haven't really thought of edge cages. And yes, this is far better than Gen AI cause of basically no hallucinations. I'm currently working on a research where both LLM and expert system can be combined, a hybrid. Bringing in the best of both worlds basically
as69:
Rule-based expert systems are underrated for this kind of thing. LLMs hallucinate legal definitions but a proper inference engine with well-defined rules will give you consistent outputs every time.

Did you model the rules from Nigerian criminal code specifically or more general common law? Curious how you'd handle edge cases like partial defenses — like if intent exists but there was provocation, does it reduce from first-degree to manslaughter in your system?
Programming › Try Out This Legal AI Expert I Built For Free by davidaluu(op): 9:20pm On Feb 23
So I built an ai expert system on a legal domain focusing on homicide basically. It's knowledge based logic not an LLM. It's just raw logic but rule based basically, the earliest and plainest form of Artificial Intelligence currently but it's as accurate as the data provided. More accurate than most general AI chatbots for specifically trained knowledge based task. Try it out here, tell me what you think

It would replace mundane and repetitive tasks but it still lacks human judgement, strategy and authencity. My verdict is it would change the landscape but not fully replace. Equip yourself with AI skills and become AI enabled instead.

Question: What do you think is the future of AI, as a digital marketer / Virtual Assistant. Is my job at risk in the long term?
Programming › Interested In Learning About Building AI? Ask Anything by davidaluu(op): 12:49pm On Feb 22
I started my AI journey back in 2024 with python using if else statements. Then I later started learning about the theory of how AI actually works, like tokenization, vector embeddings, GPT transformers and the rest eventually delving into the actual frameworks like tensorflow and Scikit-Learn. Those frameworks actually tested my patience especially tensorflow but I started using Keras for it which made it easier to use. Another challenge is that most of these AI coding sessions require massive resources like GPU instances for training so I mostly use Google Colab for coding sessions due to their generous free tier. Fast forward today, I'm still learning but have gotten better than before and have two students that I did a marathon online tutorials for. So feel free to reach out or ask any questions. Drop them here or you can email me.
Programming › Re: Should AI Be A Course Of Study In Nigerian Universities? by davidaluu(op): 8:59am On Feb 20
But it's standalone course in other countries. What's the reason it shouldn't be in Nigeria?
as69:
Honestly, yes — but not as some standalone theoretical degree. AI should be integrated into existing Computer Science and Engineering programs as a specialization track.

The problem with creating a separate "BSc Artificial Intelligence" is that AI doesn't exist in a vacuum. You need solid foundations in mathematics, statistics, programming, data structures, and software engineering before you can do anything meaningful with AI. If you skip those fundamentals and jump straight to "prompt engineering" or running pre-trained models, you end up with graduates who can use tools but can't build them or understand why they work.

What Nigerian universities should do:
- Add AI/ML modules to existing CS programs (starting from year 2 or 3)
- Focus on the math — linear algebra, probability, optimization. That's what separates someone who understands AI from someone who just calls APIs
- Include practical projects using real datasets relevant to Nigeria — agriculture, healthcare, fintech
- Partner with companies doing actual AI work so students get exposure to real problems

As for employability — the demand is there globally, but you're right that the local market is still catching up. The advantage is that AI skills are highly remote-friendly. A graduate in Lagos can work for a company in London or San Francisco without relocating.

The bigger question is whether Nigerian universities have the faculty and infrastructure to teach it properly. You can't teach deep learning on machines that can barely run Chrome.
Programming › Should AI Be A Course Of Study In Nigerian Universities? by davidaluu(op): 7:13pm On Feb 19
With the rise and advancements in AI, do you think Nigerian institutions should start offering it as a standalone course like BSC Artificial Intelligence? Other countries like US and UK already have it. Do you think it would have economic relevance? Could graduates be employable? Overseas, AI/ML engineers easily make six figures annually but I can't really see that happening in Nigeria anytime soon, what do you think?
Programming › Unseen. Create Your Own Data. Try It Out For Free by davidaluu(op): 6:59pm On Feb 15
So I built Unseen, a synthetic data engine. I needed various rare dummy datasets generated on demand like even weird combos for testing out some algorithms with Scikit-Learn and playing with some other AI framework. So I built this with Python as the backend basically with an LLM under the hood. Try it out here. Tell me what you think.

You only trust it temporarily for a task and there's no tool that does this the way I described, only automation tools yes but not for native mobile that integrates with the OS directly

Then you'll have to entrust all your data to the AI. If anyone gets a hold of that ai all your account will be compromised.


Besides they'll tools already like N8 doing this.... You can also build your own Macros to do some automations
Programming › Re: Why Aren't Mobile Phones Operated By AI? by davidaluu(op): 3:57pm On Feb 05
That's for companies not users. Haven't you thought of something maybe AI does something for you in the background on your phone instead of you doing it?

What time saver?
Companies needs real users to use their phone and play with their apps so they can show them Ads or sell something to them not AIs.
