Most usage apps lead with what you have used. This one leads with what is left.

■ One screen, three numbers

· Data left — the biggest number on the screen
· Safe per day — what you can use each day until the reset
· Days until reset

■ The widget answers without opening the app

· Same numbers, same calculation as the app
· Tap the widget to check again on the spot
· Each widget can show a different SIM

■ Automatic or by hand

· Automatic: reads mobile usage through Android’s Usage access
· By hand: type the number your carrier shows. Works with no permission at all
· Either way you can correct it to your carrier’s value anytime

■ Two SIMs

· Shows which SIM is carrying data right now — physical SIM or eSIM
· Each SIM keeps its own plan
· At 95%, an optional alert tells you which other SIM still has data

■ Travelling? Count the local SIM too

· Name a local SIM or eSIM "Travel" and count it on its own
· Enter its validity, start date, daily allowance and top-ups to see "left today" and "days left"
· Back home, just switch that SIM off — your usual SIM stays as it was

■ Android’s warning and limit, one tap away

· Opens Android’s own data warning & limit screen for the right SIM
· A warning only alerts you. A limit turns mobile data off — that is Android’s job, not this app’s

■ What is not here

· No internet permission — nothing leaves this phone
· No ads · No account · No subscription
· Everything is free

■ Worth knowing

· Android’s count and your carrier’s count can differ a little. Match it to your carrier whenever you like
· Identifying SIMs needs phone status. Android calls it “make and manage phone calls”. This app never makes calls
· Checked on Samsung Galaxy. Other phones follow Android’s standard behavior
