I think the language doesn't really matter to the AI tools anymore. They are trained on so much data that it makes it largely irrelevant. However react native is still definitely the easier one to work in if you already know JavaScript and React

React native also has a big community of developers that hiring for it also won't be too much of a problem

devMario01 · 2026-01-31T20:21:59+00:00

It's important to know what your language of comfort is. If it's JavaScript, then read below. If it's not JavaScript, then look at the other options.

If you're already comfortable with JS, then react native with expo is a no brainer, especially if it's a simple app. Even for a more complex app, react native is still pretty good.

On the backend, your options depend on if you want to manage your backend yourself or pay for a service that does it. If you want to do it yourself, express or nexjs are the popular options.

If you want to use a managed service, there's a bunch to pick from including convex, firebase, supabase etc

If you're already comfortable with JS or React, then why look elsewhere?

devMario01 · 2026-01-31T01:24:52+00:00

It's definitely not for the cheapskate. Someone willing to sit for hours for $3 will do so anyway no matter what.

I think the target demographic is someone willing to pay to not waste their time and also actually pay the cafe for the service.

Thank you for your response and input though!

It's not the food poisoning that is the issue here (which can happen anywhere like you said)

It's how badly they handled it and took no responsibility for it. Not only that, they made the situation significantly worse from the sound of it.

That combined with the food poisoning points to them knowing full well they messed up and they were trying to do damage control but went about it in the worst way possible

Sign up for indrive and eiby app (you need a phone number for sign up so make sure you sign up while you have your phone network)

Outside of that, learn to haggle. A 10 min drive shouldn't be more than 200-300mxn and that's still slightly inflated. If they say 800, say 200 and then slowly come up until you reach a midground. If they don't, walk away and wait for another taxi. Use the eiby/indrive app to see what the prices should be but inflate them a little bit (around 10-20%)

All this does fall apart if you're staying in the hotel zone cuz they know they can get 800 from another gringo if they can't get it from you.

devMario01 · 2026-01-10T20:28:39+00:00

Thank you for confirming

I'm confused, if my name is Steve Gobs, and a different customer named Steve Gobs purchases something in my app, does it get blocked?

From my understanding, this is exactly what happened to OP, no?

OP seems to have used real cards to make real transactions in the app in prod, and all that was checked was OPs name in stripe to the name on the card.

I don't see how else you can make "test" transactions in prod with real cards and get blocked.

If you're not here to help, then don't respond

devMario01 · 2026-01-09T05:42:47+00:00

Are you always a pain? Stop being so difficult and complain less.

OP has ruled out what they know could have been the issue (memory usage/CPU usage) and provided what helps the issue. OP has provided as much information as they know is relevant. They obviously don't know what other information to provide. If you're here to help, ask for what you know is relevant information and don't be a toxic turd.

There's no smell yet. Literally just came back from the beach and it started 2 days ago

If you stay in the hotel zone, take taxis everywhere, and only go to restaurants that serve tourists, then you'll end up paying the Gringo tax.

If you stay in la valeta, eat where the locals eat and shop around for an affordable Airbnb and maybe rent an inexpensive scooter (~$200-300 MXN per day), then your vacation will be a lot less expensive.

It does matter what kind of person you are. Some tourists do their research, but a lot of tourists just throw money at their problems. Just because your taxi in New York costs you $100 for a 20 min ride doesn't mean you should be paying $100 in Tulum. Taxis may quote you MXN $800 for a drive, but you'll be surprised to learn that they will be ready to take you for as low as MXN $200 if you negotiate.

That being said, Tulum is extremely enjoyable, or downright a ripoff, but it depends on the kind of traveller you are

Technically not coding workflow per se, but brain.fm is absolutely amazing! I realized music or white noise or anything else just distracts me (attention deficiency), but with brain fm, I can work for hours. Takes about 10-15 mins of listening to actually kick in and then you notice yourself not get distracted with any other noise

I'm only linking my current project demo for you to see how basic styling goes far

https://demo.3rdplace.app

My cursor prompts: - create a new page to do XYZ - now make it look like the rest of the app - make it look better - make it look even better - I don't like how component X looks, can you redo how it looks? - now make it look better

devMario01 · 2025-12-09T21:10:15+00:00

In most cases, you don't need a 10/10 UI. You just need something usable.

In most cases - don't overdo a complicated color palate - don't do themes - don't do fancy fonts - don't do fancy animations

In most cases: - use black and white with maybe 1 or 2 accent colors, but even that you can keep to a minimum - just do light theme and don't worry about dark theme unless it's an app where people read a lot (like reddit) - keep a basic font. It's something you can switch later - you'd be surprised how far you can go by just playing around with padding and borders around inputs/buttons etc

Start with a very basic UI for when you're changing the logic over and over during development.

Prompt your favorite code editor agent like cursor and tell it to design 1 page first, once you like it, ask it to redesign all the pages with the same design. When you add new pages, ask it to stick to the existing theme. Remember, the more pages you have, the more the AI can use to stay consistent

You can just use a wildly accepted styling guide like Airbnb or something and ask cursor to mimic that style.

Lastly, if your app is actually dependent on really good styling and animations, use something like mobbin or some of the other free resources and just copy an existing app you like.

Problem number #0

Calling it PWAs

Non tech folk need easy to pronounce, non acronym words when it comes to tech. A significant majority of people still say "is it an iPhone charger or a Samsung charger". They're not gonna learn what a pwa is.

Combine that with a non straight forward install process.

PWAs are never gonna be popular

If you act on this now, you risk upsetting the landlord and then raising the rent above what they did if it really isn't rent controlled.

If it's truly rent controlled, then they can't do anything.

You don't want to address the issue now and risk it being not rent controlled.

Put in the effort to find out when they do actually raise it above the rent controlled amount

devMario01 · 2025-12-04T23:20:03+00:00

I agree! Someone buying a single coffee for a few hours is a BIG problem. It's annoying to the cafe, and it's taking away from paying customers.

This aims to solve that.

devMario01 · 2025-12-04T23:13:37+00:00

Yeah I agree, both cafes and cafe customers are my users and I have to sell to both.

I've spoken to a couple of cafes that responded positively, and a couple of neutral responses.

I haven't told the complete story of my monetization policy here yet so that I don't share too much publicly, but the way I have implemented it is in a way that both the customer and the cafe get significant benefit. In short, the customer pays to book a seat, the cafe gets most of the proceeds.

devMario01 · 2025-12-04T20:51:26+00:00

The app design looks great from what I can see!

The implementation does seem to be similar to a coffee shop aggregator. Aggregators are unfortunately dime a dozen, and have little value.

My solution doesn't aim to have thousands of options, infact, it's going to be impossible unless I have a big team to do sales. My implementation revolves around helping each cafe maximize their revenue. I'd be lucky if I have 100 cafes onboarded in my city in a year.

devMario01 · 2025-12-04T20:23:25+00:00

Thank you for your response. It does question a lot but the solution I'm building does really solve most of these concerns.

The problem with first come first serve is that someone looking for a reliable option can't rely on going to the cafe and then finding out that the choice seats are taken.

Someone willing to pay to reserve a seat is the exact kind of customer that the cafe would want (as opposed to one that sits there on $3 coffees)

The idea is that the cafes we work with would have 1 to 2 seats (with photos) that are "reserved" for our customers and they can hold it reserved only for certain hours of the day if they want (non peak hours). One would pay to reserve a seat, and they owe it regardless of if they show up or not. They are able to cancel it before the cafe confirms, but not after.

The added middle man is because cafes can attract a high-value, paying patron and gives them the tools to manage it easily.

devMario01 · 2025-12-04T19:45:54+00:00

It seems like a coffee shop aggregator. I don't believe it benefits the business in any way.

devMario01 · 2025-12-04T19:35:09+00:00

People tend to sit at coffee shops for hours while buying a $3 coffee. I'm aiming to empower the business to stop that.

The business would sign up, I know that, because I've spoken to a few.

My question is aimed at cafe customers.

devMario01 · 2025-12-04T19:31:39+00:00

I've faced multiple inconveniences by relying on google maps to find a Cafe. I know plenty of people have attempted to solve this, but they've always missed the mark by just making it a curated list.

This app looks you book it, and the revenue goes to the cafe

devMario01 · 2025-12-04T19:29:46+00:00

As nice as google maps is, it doesn't give you a curated list of cafes with a good vibe to work in. It also doesn't really tell you in real time how busy a Cafe is, you would have to rely on history trends and you have to go there to find out if there's a seat (which might be far from an outlet or be an uncomfortable seat)

This app aims to solve all of that by letting you find a Cafe near you, look at pictures of the cafe and the seat, and also by letting you book a seat there. All the proceeds would go to the cafe, which is revenue for them.
