Most phones will tell you, eventually, that you’re close to your data cap. By then it’s too late to do anything but panic-close apps and hope. What they won’t tell you is which app got you there, or whether it happened on Wi-Fi (where it doesn’t matter) or cellular (where it does).

That gap is why we built Siro.

A Real Answer, Not a Guess

Siro reads your phone’s own network activity and turns it into a live, per-app breakdown: how much data each app has used, split separately for Wi-Fi and cellular, updated in real time. Your current network speed sits right in the notification shade, so you can watch it move while you’re actually using your phone, not after the fact in a buried settings menu.

Thirty days of daily history sit behind that, so a spike isn’t a mystery. Did a big download run overnight? Did an app start syncing more aggressively after an update? The history is there to check instead of guess.

Set a Limit, Not Just a Warning

You can set a monthly data cap on your own terms, tied to your actual billing cycle rather than the calendar month, with alerts as you approach it. If you want to be strict about it, Siro can automatically cut off further mobile data use once you hit your critical threshold, so going over isn’t something that can happen by accident while you’re not looking.

Siro Pro goes a level deeper with per-Wi-Fi-network usage: it separates your usage by which Wi-Fi network you were actually connected to, so you can tell your home connection apart from a coffee shop hotspot or a metered mobile hotspot you’re borrowing for the day. Pro also adds a Data Vault for archiving older history and a per-app analytics view for anyone who wants to go further than the daily numbers.

Local By Default

Everything Siro reads about your network usage stays on your device unless you turn on Google Drive backup yourself. Siro doesn’t need your data to be sold anywhere to be useful, it just needs to be visible to you.

Available Now

Siro is available now on Android. If you’ve ever been surprised by a data bill, or you just want to know what’s actually happening on your connection, Siro from Mosh Labs is built to answer that. (If you’re looking for a different, unrelated “Siro” product, ours is specifically the data usage tracker, not a sales or AI tool.)
