  Implementing this idea as a web app instead of an iOS exclusive seems like the right move.
square_usual 6y ago
That's a snazzy looking app, but why iOS only, and why iOS 14 only?
- joeblau 6y ago
  I’m testing a bunch of SwiftUI2 features right now so it’s constrained to iOS 14 for them. If you’re on the beta, you’ll get it when iOS 14 is released.
- BjoernKW 6y ago
  As for iOS-only I’d assume lack of resources. Developing and maintaining an app on multiple platforms (and keeping the code bases in sync) is no small undertaking (hence the existence of write-once / hybrid app frameworks such as Ionic). Regarding iOS 14 my guess is SwiftUI.
- JoshTriplett 6y ago
  In particular, why not a webpage? This doesn't need to be an app.

    Probably a side project for a full time iOS dev who wanted an excuse to mess about with SwiftUI and decided to use the tool they are most familiar with

What an excellent pitch! It's right there at the top, and it says exactly what the app does. This is a refreshingly straightforward design.

WiFi speeds fluctuate heavily, e.g. workdays vs weekdays, lunch hours vs mornings vs nights, etc. So as good looking as this app is, the real challenge is with the accuracy of its data and keeping it from getting stale. Not sure if the OP realizes this, but it's a 24/7 grind that also requires a sizable userbase. It's not a bad idea in its core, but this belongs in the OS itself and it should also be On by default to manage to collect enough data to be useful and to keep it current. I doubt that an opt-in model, especially in a form of an installable app, would work well enough to produce any reasonable coverage.

I heard of a similar idea in an Acquired episode: https://www.acquired.fm/episodes/special-acquired-x-my-first-million https://www.acquired.fm/episodes/special-acquired-x-my-first... Wondering if this is somehow related, or you came up with the same idea independently

  This is actually what I was listening to on Friday morning that prompted me to build this.

    How long was the build time start to finish?
    - joeblau 6y ago
      30 hours not including 8 hours of sleep, 1 hour bike ride, shower, eating and all of that fun stuff.
sammy2244 6y ago
Seems like a cool idea, but when you are testing download/upload where are you testing to? When I visit Google’s speedtest it shows me drastically slower speeds than if I go to fast.com or speed.cloudflare.com. Speeds to AWS cloudfront, fastly, cloudflare, google will always be different especially in countries /areas without PoPs

I moved recently from the UK, where my home and office both had fiber, to live in a tiny picturesque village in the Istrian hills in Croatia. Initially, my 4g router was getting a signal strength of -110 to -120db, corresponding to two bars and zoom video not working. Spent €90 on an outdoor aerial. Plugged it into the router. Signal now averages -85, four to five bars on the router, zero issues with video calls. My point being: there’s more than one way to skin a cat and you can often improve your mobile signal if you want to.
- sails 6y ago
  Would appreciate a link to your researched aerial and router. I'm sitting in the country with my phone in a metal kitchen bowl (DIY aerial) for maximum signal, and think I could benefit from some technology!

    Take a look at the Teltonika RUTX11[1] with a MIMO LTE antenna from Poynting[2]. Not cheap, but certainly got good results with it. I used Cellmapper[3] to check where the closest tower was. I have heard that the Huawei ones that accept external antennas are also decent, be it with a much smaller featureset.

I like this idea, but I see two potential problems: 1. It might route too many people to where the network is fast, thus making the network not fast anymore and wasting a lot of people's time as they "go." 2. It might also route a bunch of "digital nomads" to my local art café where they will hog the tables, like Waze did with commuter traffic to my residential street. How do you avoid those two problems? Or at least the first one, which is a problem for your target users?
- renewiltord 6y ago
  Make your internet slow at #2. Presumably you don't want an army of people all on the Internet at your art cafe anyway. As for #1, there are physical capacity limits you are likely to first exhaust. Only so many people will fit.
  - biztos 6y ago
    Actually two of my cafés have a "no computers in the evening" rule, one also has a "no computers on the terrace" rule. Now that I think about it more, with fast mobile data I don't think network speed is going to be much of a factor for places like that. For #1, if you have ten people all on Zoom meetings at the same time, isn't that going to kill your fast-for-a-café bandwidth?
    - Dylan16807 6y ago
      Even on sub-par infrastructure, a business-class connection should never be slower than 100/100mbps, and 10 people on zoom wouldn't be a problem. So the question becomes whether the infrastructure is garbage.
      - dylz 6y ago
        This depends heavily on type of connection. 100/100 should be bare minimum, yes, but for example Comcast coaxial business-class is still like 5-10mbit up.
griko 6y ago
Love the app! Straightforward with no extra stuff here and there. I’d like to share some suggestions after using it for a while: - adding an option to partially omit or edit the address would be great since not every part of the world shows the exact address accurately - inform what datas are stored (i did wonder why they show the latitude and longitude, because privacy reasons) - add prompts for isp/carrier provider, subscription/plan type, and other granular details so people know what to pick or expect - minor improvements on the user interaction, like autofocusing on the input so users can instantly type, or tap an entry to view more details Overall, looking forward to share the app to my fellow iOS 14 users!
bajsejohannes 6y ago
Sorry for being pedantic, but this app is measuring bandwidth, not lag (latency). See for example https://en.wikipedia.org/wiki/Lag https://en.wikipedia.org/wiki/Lag
areille 6y ago
Nice app, do you plan to develop an Android version ? However, I'm not sure to agree with all your points. Since two weeks I work at my grandpa's in French countryside. 2.7Mbps download and 0.5Mbps upload. I can use Zoom (no video), watch Youtube (480p), and use Slack with no problem at all.
harha 6y ago
One more issue when going somewhere: not all places have useful 4G offerings. In France, Germany and Italy for instance I couldn't find a monthly prepaid 4G offer with unlimited data, especially in France you frequently even need a local bank account and in Germany 4G is so bad in many places that it wouldn't make a difference how much data is in the plan. Other places like Austria offer monthly prepaid as low as EUR 20, though speed may be limited to 25-40Mbps, which should suffice for 1:1 video calls. My solution for now is to at least have my workstation connected somewhere with a fast connection and someone who could reboot it if needed, connect to that from where I am and have that do all the heavy lifting. Doesn't solve the video conference issue though. Having flexible and reasonably quick connectivity, or an EU wide subscription, would really lift the value of locations outside of cities - I don't understand how badly this is done compared to other infrastructure investments (e.g. roads are pretty amazing in Western Europe and not that bad in places I've been in Eastern Europe compared to the US). I hope non government actors like Starlink manage to close this gap.

Are there any details on who's providing this app, who's running the site, and what they'll do with collected data? The ToS and privacy policy are identical, and only refer to an app called "velo" and a company called "copilot LLC", and that their method of contact is "Joe Blau." This seems very strange to me. (unless this is a "move fast, break things, collect GDPR fines" sort of thing)

This seems like another "silicon valley" issue, solving problems for an elite few people in society who have the luxury to bum about for 6 months working in hostels (if you can truly say they are working as effectively as they did before they put a backpack on).

I found this service quite useful, thank you! But please, why it should be a mobile app? Looking at the landing page animation it looks like there's nothing plain (like in "jQuery only for fancy animation") web site cannot do.
somada141 6y ago
As others have mentioned the bottleneck is typically getting a good mobile plan especially if you intend to move around a larger region across borders. The EU has sort of gotten to a point where roaming costs are no more (with the right plan). E.g. I have 20GB/m I can use anywhere in Europe for 20pounds/m (Vodafone) without incurring roaming costs but once you introduce video-conferencing or video streaming that's not gonna cut it regardless of how good the signal is. Thus I've found in the past 11 months that I've been nomadicking around Europe that you often depend on getting some good wifi which is quite the hassle (especially in rural destinations). I have high-hopes for apps like this to create a knowledge-base for areas with good broadband.
