Days become a pattern.
Watch a week, a month, a peak day. Set a threshold and Dataly tells you when a day is running hot, before the bill does.

It's rarely just one device.
Check your Mac from your phone. Check your phone from your Mac. Dataly adds them up so you can see which one is actually using the connection.
Each device reports one thing to the other: its own daily download and upload total.
Pairing takes about ten seconds.

They stay in touch locally
Paired devices exchange their daily totals over your own network.
Numbers travel. Nothing else does.
Pairing two of your devices lets them tell each other how much data they used. That is the entire conversation, and it happens on your local network.

Questions
- What is Dataly?
- Dataly is a free data usage monitor for iPhone, Android and Mac. It tracks how much mobile data and Wi-Fi each device uses by day and month, shows which apps use the most on Android and Mac, and adds your devices together when you pair them on the same Wi-Fi.
- Can Dataly show which device is using my Wi-Fi data?
- Yes, for the devices you install it on. Pair your iPhone, Android phone and Mac once with a short code and you see each one's usage side by side, with a combined total. There is no router setup. Devices without Dataly, such as a smart TV, are not counted.
- Does Dataly show data usage per app?
- On Android and Mac, yes: you get a list of apps ordered by how much data they used. On iPhone, Apple does not let apps see per-app usage, so Dataly shows the iPhone's total and the iPhone's own Settings shows the per-app list.
- Can I set a data limit and get an alert?
- Yes. Set a daily limit and Dataly alerts you when you pass it. iPhone has no built-in data cap, so this is the simplest way to get a warning before your plan runs out.
- Is Dataly free?
- Yes. The iPhone and Android apps are free and show ads. The Mac app is free and has no ads.
- Can Dataly see what I browse?
- No. Dataly counts how much data a device uses, not what the data is. It never reads your browsing, messages or files, and your usage history stays on your devices.
- Is Dataly the same as Google's Datally?
- No. Datally was a data-saving app from Google for Android that was shut down in 2019. Dataly is a separate app, made by OneWave, that tracks data usage on iPhone, Android and Mac.
