What Netly does
Netly answers three everyday questions about your connection: how fast is it, what can it handle, and who is sharing it. It has four tabs:
| Tab | What you do there |
|---|---|
| Speed Test | Measure download, upload and ping in about 30 seconds and get a plain-language verdict such as “4K streams fine, video calls too”. |
| Video Test | Play a real 720p clip for about 17 seconds and see whether it loads fast, buffers, and plays smoothly. |
| Stats | See which networks you test on, average speed per network, and how much data Netly itself has used. |
| Settings | Language, notifications, about, terms. |
There is no account and nothing to sign up for. Every result is saved on your phone only.
First launch and permissions
The first time you open Netly you will see two short screens explaining what the app does, then one or two permission requests. You can decline any of them — the app still works.
| Request | What to choose | What it unlocks |
|---|---|---|
| Location | iOS: Allow While Using App with Precise: On · Android: While using the app + Precise | The Wi-Fi network name (e.g. “FPT_Home 5G”) in your history instead of “Wi-Fi”. Location is read only while the app is open and never sent anywhere. |
| Phone (Android only) | Allow | Correct 4G/5G labels and dual-SIM detection. Android words this as “make and manage phone calls” — Netly never calls or reads contacts. |
Run a Speed Test
Open the Speed Test tab.
The chip under the logo shows the network you are on. Your last result and its verdict sit in the card at the top.
Tap the big blue SPEED TEST button.
The test runs three phases: Ping (latency), Download, Upload. A gauge shows the live value and a chart shows the last 30 seconds; jitter, packet loss and the server in use update underneath.
Wait about 30 seconds.
On iPhone (iOS 16.1+) progress continues in the Dynamic Island and on the Lock Screen; on Android a notification shows progress. Either way, the Speed Test keeps running if you leave the app.
Read the results screen.
Download, Upload and Ping are shown large. Tag where you tested — Indoors or Outdoors — so History can compare like with like. You can jump straight to a Video Test from here.
Read your results
| Number | Meaning | Good for most homes |
|---|---|---|
| Download (Mbps) | How fast data arrives. Decides streaming quality and page loads. | ≥ 25 Mbps for 4K; ≥ 10 for HD |
| Upload (Mbps) | How fast data leaves. Decides video-call quality, photo backup. | ≥ 5 Mbps per simultaneous call |
| Ping (ms) | Round-trip delay. Decides how responsive calls and games feel. | < 50 ms; < 20 ms for gaming |
| Jitter (ms) | How much ping varies. | < 10 ms |
| Packet loss (%) | Share of data that never arrived. | 0–0.5 % |
Verdicts
Netly turns the numbers into one line you can act on:
| Verdict | When |
|---|---|
| 4K streams fine, video calls too | Download ≥ 25 Mbps and ping < 50 ms |
| HD streams fine, video calls may stutter | Download 10–25 Mbps and ping < 80 ms |
| Enough for browsing and messaging; video may pause | Download 3–10 Mbps |
| Very weak — try again closer to the router | Download < 3 Mbps or ping ≥ 150 ms |
Ping thresholds apply on top of download: when the ping condition is not met, the next lower verdict is shown. A verdict describes the moment you tested — run two or three tests at different times before drawing conclusions about your plan.
Run a Video Test
Open the Video Test tab and tap VIDEO TEST.
Netly streams a real 720p sample clip (about 15 MB). Keep the app open for the roughly 17 seconds it takes.
Watch the live meters.
A progress ring shows how much of the clip has played; buffering count, smooth-playback percentage and bitrate update every second, with a smoothness chart underneath.
Read the three results.
Load time — seconds until playback started (under 2 s feels instant). Buffering — total seconds the video froze (zero is ideal). Smooth (shown as “Smooth playback” in the explanation) — share of time it played without interruption (above 90 % is comfortable). Tap the ⓘ on any of them for a one-line explanation. Leaving the app during a Video Test cancels it.
The verdict (for example 720p plays smooth, no freezes) applies to the resolution tested. If 720p is smooth and your download speed is above 25 Mbps, 4K will normally be fine too.
History and test details
Tap History on the Speed Test tab (or Video history on the Video Test tab). Two sub-tabs — Speed and Video — list every test with its network, its Indoors/Outdoors label (or the resolution for video tests), date and the three headline numbers.
Tap any test to open Test details:
- Tech details — Wi-Fi BSSID, public and local IP, jitter, packet loss and “Drop from peak” (how far the average fell below the fastest moment of the test).
- Labels & notes — switch Indoors/Outdoors and add a note such as “near the 2nd-floor router, door closed”.
- Delete test — removes this one test after confirmation.
Stats
Stats are built only from the tests you ran — Netly never monitors your network in the background. Two views, switchable from the first dropdown:
- Networks tested — how many tests you ran in the chosen period, split by network type (Wi-Fi, 5G, 4G…) plus Offline (tests that failed because the connection dropped). Average download speed per network counts completed Speed Tests only; Video Tests count toward the totals but not the averages. Tap ⓘ next to the count to see how it is calculated.
- Data used for testing — the megabytes Netly itself transferred over mobile and over Wi-Fi (including tests you cancelled or that failed), split into download and upload. This is Netly’s usage only, not your phone’s total; for that, open your phone’s Settings → Cellular / Data usage.
The second dropdown chooses the period: Today, Yesterday, Last 7 days, This month, All time.
Who’s on my Wi-Fi? (iOS)
Open “Who’s on my Wi-Fi?” from the Speed Test tab.
You must be connected to Wi-Fi. The entry point sits on the Speed Test tab, below your last result.
Tap Scan network.
The first time, iOS asks for Local Network access — tap Allow. The scan takes about five seconds and shows the number of devices connected, then a list with each device’s local IP address. If you declined the permission or you are on mobile data, the screen shows “-” and a hint to fix it in Settings.
Identify devices.
Netly labels your Router and This phone; everything else is “Other device”. iOS does not expose device names, so to identify one, switch it off and tap Scan again.
If a device remains unexplained, change your Wi-Fi password in your router’s settings. Nothing from the scan is stored or sent.
Dynamic Island, Lock Screen and widget (iOS)
- Live Activity — when you leave the app during a Speed Test, the current phase and live speed appear in the Dynamic Island (iPhone 14 Pro and later) and on the Lock Screen (iOS 16.1+). Tap it to return, or swipe to hide it while the test keeps running. It disappears on its own a few minutes after the test finishes.
- Home Screen widget — long-press your Home Screen → + (on iOS 18: Edit → Add Widget) → Netly. It comes in one medium size. The widget shows your last download, upload and ping and when you tested. Tap it to open the app. It updates only when you run a new test, so it does not drain your battery.
Settings
| Setting | What it does |
|---|---|
| App language | Choose from 20 languages, including Arabic, Urdu and Persian with right-to-left layout. Synced with your phone’s per-app language setting. |
| Notification style | Silent (icon only), Vibrate, Sound or All. On Android this sets the notification channel; on iOS it decides whether reminders arrive with sound, while banners and badges follow Settings → Notifications → Netly. |
| Test reminders (iOS) | A nudge to run a test every few days — at most 2 a week, never between 10 PM and 8 AM. Turning it on asks for notification permission. |
| Offline alerts (Android) | A notification the moment your phone loses its connection, at most once per 15 minutes. |

Notifications
Netly sends only what you switch on. Reminders can be stopped in Settings at any time; on Android, an offline alert also carries a Turn off alerts action so you can silence it in one tap. If notifications never arrive, check that Netly is allowed to notify you in your phone’s Settings and that the switch in Netly → Settings is on.
Get an accurate result
- Test where you use the connection. A result next to the router tells you what your provider delivers; a result on the sofa tells you what you actually get. Tag them Indoors/Outdoors and compare in History.
- Pause heavy traffic. Downloads, cloud backups and 4K streams on other devices share the same pipe.
- Prefer 5 GHz Wi-Fi when you are near the router; 2.4 GHz reaches further but is slower and busier.
- Test at different times. Evenings are usually slower. Three tests across a day tell you more than one.
- Mind your plan on mobile. Each Speed Test costs about 12 MB, each Video Test about 15 MB; Stats keeps the running total.
Troubleshooting
| What you see | What it means | What to do |
|---|---|---|
| “Connection dropped mid-test” | The phone went offline during the test; finished phases are kept. | Check Wi-Fi or mobile data, tap Resume test. |
| SPEED TEST button can’t be tapped, chip says Offline | No connection right now. | Connect to Wi-Fi or turn on mobile data; the button becomes active again. |
| “Connection dropped mid-test” appears before any phase finished | No measurement server answered. | Check your connection, then tap Resume test; Netly re-selects the fastest server. |
| History shows “Wi-Fi” instead of the network name | Location permission off, Approximate (Android) or Precise Location off (iOS), or Location switched off for the whole phone. | iOS: Settings → Netly → Location → While Using the App, Precise Location on. Android: Settings → Apps → Netly → Permissions → Location → Use precise location. |
| Mobile tests labeled “Mobile” instead of 4G/5G (Android) | Phone permission declined. | Phone Settings → Apps → Netly → Permissions → Phone. |
| Wi-Fi scan shows “-” and a Settings hint | Local Network permission declined, or you are on mobile data. | Connect to Wi-Fi; iOS Settings → Netly → Local Network. |
| No reminders arrive | Notifications blocked, or quiet hours. | Allow notifications for Netly; reminders never arrive between 10 PM and 8 AM. |
