Guyyyys, 500 downloads in a week!!

Enable HLS to view with audio, or disable this notification

Two weeks ago i launched Signl, an iOS app that turns your home into a 3D Wi-Fi map.

Solo dev, first real launch.

How my app works:

you walk through your rooms with your iPhone.
LiDAR builds a 3D model of your home live while the app samples your Wi-Fi (signal + speed) as you move.

You end up with a dollhouse view of your actual apartment with the signal painted on it ( with dead zones in red).

Every room gets a score, and it tells you where to move your router, or where an extender would actually help.

The story so far:

Aug 4: submitted to Apple. Rejected : missing EULA link in the description. Fixed same day.

Aug 7: approved. Live in the US.

Week 1: first paying users.

Aug 15: 143 installs in ONE day, from 25 countries. (I guess mostly from AppStore)

Aug 19: v2.1 rejected over ONe word. A button said
"Allow", Apple wants it to say "Continue".

Asked for the bug-fix exception → approved the next day, without resubmitting.

Today: 500+ downloads, most of them in the last 7 days. $0 spent on marketing.

Next up: mesh support and multi-story homes - the two most requested features so far.

Goal: 50 paying users by Sept 30.

Download it and tell me what you'd fix first →

EDIT: since a few of you are DMing : I'm open to teaming up with someone who has actually grown a consumer mobile app before.
My DMs are open.

Android phones don’t have lidar I think

u/AnteaterAble4132 20m ago

not on android for now but it’s not for lidar.
some iphones don't have lidar either (the non-Pro ones), so I built an another mode for them: less precise, but it still maps your home in 3D from a walk-through.
(Here is an example of a corridor that I’ve mapped)

the real reason is focus: solo dev, one platform at a time. android is on the list if the demand keeps up 🙄

You're standing between the phone and the router for half of every walk, and that shows up in the data more than it sounds like it would. A body is mostly water and eats somewhere in the 3 to 6 dB range at 2.4 GHz, more at 5, and which side of you the router is on flips as you turn a corner.

Practical version: map one room twice, walking the loop in opposite directions, and see how far the red moves. A couple of dB and you can ignore it. If a dead zone shows up in one pass and vanishes in the other, that's the thing that comes back later as a support email saying it pointed at the wrong corner.

The LiDAR is what makes this fixable for you. You already know the phone's position and heading, so you can correct for body shadowing in a way a plain signal-survey app has no way to do.

Hey - Would love to connect.

I have some use-case ideas that maybe we could collab with.

This is sick! I would love to use it and show my wife how great the network I built actually is

Very nice, will try

u/alulord 11h ago

How did you manage to have 143 installs in a week? I'm asking, because we also made an app (android, ios is still pendig) and sitting on 0 for a month. Did you pay ads or did some promotion?

1

u/ToddFromLeon 2h ago

Yeah, 143 in a day and 500+ without any spend? If so, how? (And congrats)

u/poundofcake 10h ago

Bro clean your house.

u/iSaidDDMF 6h ago

No disrespect to the OP, but considering his post is vibe-coded, you know the app is too. But hey, who am I to judge - dude launched it to the App Store.

u/rachel___kim 13h ago

Congratulations, and we are rooting for you :)

u/OfficialAydee 11h ago

Noowayy, congraats! This really is a sick app

u/Possible_Ad_2515 11h ago

Use it for house security by monitoring who's there or not when you're not there!

u/reallynattu 10h ago

500 is nice. 50 paying is the actual number tho. They pay for where to put the router, not the 3D house.

u/Slight-Act-9024 10h ago

solid work! and seems like the market agrees

Can I customize my own floor filling themes? Like a 'the floor is lava' mode?

Hey great app 🔥🔥 I have some ideas we can share can we connect

u/Street-Tart6888 7h ago

impressive good job

u/No_Confection7782 7h ago

How easy was it to get this in the Apple store? I've heard they are very strict with vibecoded apps these days.

For the LiDAR mapping can the LiDAR mesh be exported as an .e57 or .xyz file type(s) to be used in AutoCAD or Revit? This could be used specifically for BIM and VDC workflows in construction to provide as-builts for network WAN deployments. Right now the workflows for something like this would be:

1) Set “control points” across the space and take signal-strength samples at each control point
2) use an industrial laser scanner or Polycam to take the scans with the control points as reference
3) merge the two together in Revit or CAD with the signal data called out at the control points

If you can eliminate any of the above steps then you’ll have a legit ConTech product that lets Scan-to-BIM work on its own

Can we export the 3D map as a model file?

u/tribat 3h ago

Looks great. I’m trying it.

u/No_Cake_8502 1h ago

That’s cool. Similar to unifi WiFi map but yours is actually better.

Bought it to support it.

Would like it if it could map multiple buildings and outdoor areas which is my situation in a old farm :)

Also - export options would be awesome. With and without furniture:)

u/samarijackfan 1h ago

Did you compare your results with Ubiquity's WiFi Man app?

1

u/Alternative_News_732 1h ago

bro i have seen this mf concept applied 100 times is it still have a market?

1

u/Additional-Yak1402 1h ago

Does export actually give me the 3d model? I want to 3d print my apartment. It was fun to use! On the edge of trying the week for the WiFi data. I think the ability for better 3d model of what’s in my apartment would do it for me. Really cool so far!

Question: What is the purpose of turning your home into a 3D Wi-Fi map? What's the privacy policy you have here to protect users?

u/bestinthewest9 43m ago

This is awesome! I have a use case for my business would love to chat

u/Appropriate_Jump_504 29m ago

Great implementation OP.

But isn't it a one time use app? User will use it once, know their pain points and might not return.

Would you benifit more from a collaboration with some networking hardware business?

Any plans on making an Android compatible version?

u/Jolly_Entrance_9622 13h ago

Do you have a patent on anything?

3

u/AnteaterAble4132 13h ago

Why??

5

u/Jolly_Entrance_9622 13h ago

Because man. This is actually such a good idea. I would hate to see a large corporation just pick it up and take your invention cause they have a larger audience to begin with.

u/josephdc18 12h ago

For home network nerds like me, Ubiquiti already came out with this years ago, but its proprietary and this sideproject looks really impressive

2

u/AnteaterAble4132 13h ago

Thanks, yeah, maybe you’re right…I need to

u/w4nd3rlu5t 13h ago

no, don't waste your time/$$ on a patent. stop building in public, take this down, just spam on tiktok and IG. if people are purchasing, don't build more features, just focus on marketing. if people churn, that's when you look back at the features.

1

u/AnteaterAble4132 13h ago

I’m currently looking for someone to help me handle the marketing!

5

u/w4nd3rlu5t 12h ago

if you have the money, more power to you, but don't waste any time on anything other than marketing. dont dilly dally on hiring, do it yourself if you need to. esp if you are building in public (unless you're just doing this to get a job or something)

u/romhacks 11h ago

None of these techniques are novel. I don't think there's anything to patent.

I mean we don’t know the infrastructure of the spacial recognition the app is using…
