Internetno answer
Past your router
Your own router kept answering, so your home network was fine. The connection stopped beyond it: the modem, the line or the provider.

Internet monitor for iPhone and iPad
Catch your internet drops
Leave a spare iPhone or iPad on the charger. LineProof writes down every drop with its date and time, shows whether your router or the line past it failed, and turns it all into a report and a letter for your provider.

How it works
Three steps. Then it watches the line for you.
No account and nothing to install on your router. Just a spare device, the charger and LineProof open on screen.
- 01
Put a spare iPhone or iPad on the charger
Any iPhone or iPad with iOS 17 or later. Put it where your Wi-Fi is normal, like the room where you work or play, and plug it in.
- 02
Leave LineProof open
Every 15 seconds it quietly checks whether the internet answers, every 5 seconds during a drop. You choose 10 to 30 seconds. The screen dims itself while it logs.
- 03
Send your report
LineProof turns your log into a PDF report and a letter in your name. Send it from Mail with the report attached, or share it anywhere. Only you send it.
Router or line?
Know where it broke, every time
When the internet stops answering, LineProof checks your own router and whether web addresses still work, and notes what failed. So every drop says where it happened: in your home, or past your router.

Internetnot checked
In your home
Your router did not reply, so the problem was in your home: the router, its power or the Wi-Fi. It is in your report.
Not counted against your provider

Web addressesno answer
Web addresses
The internet answered, but web addresses could not be looked up (DNS). Websites and apps stop working when that happens.
Counts in your letter
Allow the local network check when the app asks: only your router is checked, and nothing leaves your home network. Without it, every drop is still logged, but the app cannot tell your router apart from the line.
The report and the letter
A report your provider can read in a minute
Dates, start and end times, how long each drop lasted and whether your router still answered. With a cover page, a summary, day timelines and every drop, plus a letter in your name that you can edit.
- Cover and summary
Your name, address and customer number, the period, how many drops and how long you were down. - Every drop
Date, start, end and duration, and whether your router still answered. Day timelines and the longest drops. - A letter in your name
In English, Dutch or German, yours to edit, plus a follow-up letter when it keeps dropping after you called. - Send it from Mail
With the PDF attached, or share it anywhere. Only you send it. Spreadsheet export (CSV) too.

History
See when it drops
Every day at a glance, every drop in detail, and a week map that shows the hours it keeps happening.
- Every day at a glance
A ribbon per day with each drop on it, and the details of every drop: when, how long and what answered.
- This was me
Restarted the router yourself? Mark that drop and it stays out of the letter.
- Your case
Your calls and tickets with your provider, with dates and reference numbers, and what you already tried. It all goes into the report.
- A nudge when logging pauses
If you turn it on, a reminder tells you when the app left the screen.
The spare phone
Made for the spare phone on the charger
An old iPhone or iPad is perfect. LineProof keeps its screen calm and dark while it logs, and tells you plainly when something needs you.
- Plug it in
The screen stays on while logging, so use the charger. The app tells you when it is not charging.
- Keep it in the app
Guided Access keeps LineProof on screen. The app shows you how to turn it on.
- Even better: a cable
With a USB Ethernet adapter, a cable to your router takes Wi-Fi out of the question, and your report says so.
- Honest gaps
iPhone and iPad pause apps you leave. Those times are marked as not logged, so your record stays honest.
Privacy
Your log stays with you
LineProof has no account, no ads and no tracking. We never receive your log.
- On this device. Your log stays on this device and in your own backups.
- Tiny checks. The checks ask Apple, Google or Cloudflare for a tiny answer that carries nothing about you.
- Your router only. The local network check talks to your router and nothing else.
- Apple handles the purchase. We never see your payment details.
Questions
Good to know
Does LineProof log in the background?
No. iPhone and iPad pause apps you leave, so LineProof logs while it is open on screen. That is why a spare device on the charger is the easy way.
Times when it was not logging are marked in your log, so your record stays honest. If you turn it on, a reminder tells you when logging pauses.
Do I need a spare iPhone or iPad?
It is the easy way, because the app has to stay open. Any iPhone or iPad with iOS 17 or later will do. You can also use your own iPhone for an evening, as long as LineProof stays on screen.
What does it cost?
Logging, the live screen, the router or line verdict, the week map and the last 24 hours in full come with the app.
The full report (your whole history, the PDF report, the letter and the spreadsheet export) is a one-time in-app purchase. No subscription. With Family Sharing it works on your family's devices too, and a sample report shows exactly what you get before you buy.
Will my provider accept the report?
The report is a record of what this device measured, not an official measurement. It gives your provider the facts they usually ask for first: exact dates and times, how long each drop lasted, whether your own router still answered, and whether it was measured over Wi-Fi or a cable.
Wi-Fi or a cable?
Both work. On Wi-Fi, put the device where your Wi-Fi is normal, not right next to the router and not at the edge of your Wi-Fi. With a USB Ethernet adapter, a cable to your router takes Wi-Fi out of the question, and your report says it was measured over a cable.
Why does it ask for my local network?
To check whether your own router still answers when the internet drops. Only your router is checked, and nothing leaves your home network. Without it, every drop is still logged, but the app cannot tell your router apart from the line.
Which languages?
The app, the report and the letter come in English, Dutch and German. You pick the language of the letter, whatever language your device uses.
Where is my log kept?
On this device and in your own backups. No account, no ads, no tracking. A report leaves your device only when you share it yourself.
Start your log tonight
Put a spare iPhone or iPad on the charger, open LineProof and let it watch the line. Next time your provider asks when it happened, you will know.
