How it works
What you notice, not what happens inside.
Lagbuster sits between your phone and the Internet. You turn it on once; from then on, when the network gets bad, your connection keeps going instead of freezing. We describe what it does. How it does it is patent pending.
What changes for you
Four things you notice on a bad network.
Pages keep loading.
Where a page used to freeze half drawn, it finishes. Slower on a terrible network, but it finishes.
Video keeps playing.
Fewer frozen pictures and spinning wheels when the signal drops for a moment.
Fewer cuts when you change networks.
From wifi to mobile data and back, Lagbuster is built to keep your connection going instead of starting from zero.
Short blackouts do not end the download.
When the signal comes back after a few seconds, what you were doing carries on by itself.
Measured
What the measurements show.
We put the same iPhone through the same network, with and without Lagbuster, on the same site: in our lab with controlled losses and short blackouts, and outside on real mobile networks. Every number carries the identifier of the run that produced it.
- 85%packets lost, pages still loadWith six of every seven packets lost on the way, pages still loaded. Without Lagbuster, the connection timed out every time.
- 50%lost, still 10 megabitsWith half of everything lost on the way, Lagbuster still moved 10 megabits per second. Without it, the connection could not even start.
- 6 sblackouts, the download goes onTwo six-second blackouts in the middle of a 50-megabyte download: it finished on its own, without reconnecting.
- x2.8downloads on real 4G with 10% lostOn a real 4G network losing one packet in ten, downloads ran almost three times as fast as without Lagbuster; losing three in ten, only Lagbuster finished.

The fine print, first
What it does not do.
We publish the limits next to the gains, on this page and on the home page.
It does not make a good network faster.
On a good network you may notice a small toll today, mostly when a connection starts. The gain is where the network is bad.
On terrible networks it works slower, not at full speed.
Slower, but it works.
With no signal at all, nothing gets data through, Lagbuster included.
It covers the stretch between a bad connection and no connection.
Battery use on phones has not been measured yet.
We will publish it once it has.
Your part
What we ask of you: almost nothing.
Turn it on and leave it on.
Or switch on Auto-connect, and Lagbuster turns itself on when you use mobile data.
Pick a mode.
Fast for everyday use. VPN when you want to stay hidden or appear from another country.
Tell us when something fails.
"Something wrong?" sits at the top of the app. It sends us what happened to the connection in the last couple of minutes, never what you were doing.
See it on your own phone.
Ask for beta access and try it where your network is worst: your commute, your hotel, your stadium.
