One-time purchase: no subscription, no ads — Home, Lock Screen and StandBy widgets included, not a Pro upgrade. See data left from your own plan date, alerts at 80%.
See how much data you have left this cycle — and whether you’re heading for overage. Track against your own plan date: remaining on the Home Screen, Lock Screen, and Apple Watch, with optional alerts at 80% or when you run out. No carrier login, and no extra data used just to check. It is a one-time purchase: no subscription, no ads, widgets included.
ONE-TIME PURCHASE. NO SUBSCRIPTION.
Buy once and everything below is included:
• No subscription, no trial that expires, no “Pro” tier added later
• Home Screen, Lock Screen, StandBy and Apple Watch widgets are part of the app, not an upgrade
• Nothing you already paid for gets moved behind a new plan later
YOUR PLAN DATE, NOT THEIRS
Usage in Settings doesn’t follow your billing date, and carrier apps want an account. Data Widget totals cellular bytes on-device against the cap you set:
• Monthly, weekly, or a custom cycle
• Calibrate to the number on your bill (confirms before saving)
• If your plan rolls unused data, carry it into this cycle
• Dual SIM / eSIM: both lines together, primary only, or split — useful with a travel eSIM
• 5G and LTE cellular interfaces
REMAINING VS. PACE
The headline number is remaining. Time and usage share one bar; the arrow is calendar pace — green if you’re under, red if you’re burning faster. Home says “12% ahead of pace” or “about N days left at this rate,” with a daily chart for spikes. History is one row per cycle, grouped by year.
GLANCE WITHOUT OPENING THE APP
Widgets on the Home Screen, Lock Screen, or StandBy show remaining in large type, plus when it last updated. Apple Watch complications show remaining on the face. In the app, tap to switch % and used | remaining.
BEFORE YOU OVERAGE
Optional alerts at 80%, 90%, or when you run out — once per tier each cycle. You can also alert when usage runs ahead of time.
PRIVATE AND HONEST
No ads. No location. No SMS scraping, no carrier-bill login.
On-device totals can differ from Settings > Cellular because of VPN, Personal Hotspot, or carrier rounding. That’s explained in Settings; calibration lines the ledger up with your plan.
Requires iOS 17 or later. Apple Watch requires watchOS 10 or later. Designed for iPhone. On iPad it only counts on cellular models.
The only downside is that Data Widget does not track data when Hot spot is used.
Developer Response
Version 4.3 is on the App Store. Widgets were rebuilt with WidgetKit and work again on iOS 18 and later — Home Screen, Lock Screen, and StandBy. Apple Watch can show remaining too. They refresh on their own, so the numbers keep updating even if you never open the app.Please update to 4.3, then long-press the Home Screen and add Data Widget again. The old Today widget does not come back by itself. Still a one-time purchase: no subscription, no ads.

Five Stars But...
Lauxmyth
Do love this but it does not use screen space very well. If you go over on one day, the graph gets compressed even as there is ample room to show without pressing everything flat.
Developer Response
Thanks for the chart note — 4.3 stops a single oversized day from flattening the whole graph. Please update to 4.3 if you have not already. Widgets on current iOS are back too.
iOS 18 compatibility

Looks like it doesn't work anymore on iOS 18...

This version is close to a rewrite. Three things you'll notice: widgets render properly again on current iOS, you can ask how much data is left without opening the app, and the home screen tells you whether it will last — not just a percentage.
WIDGETS ARE BACK, IN FOUR PLACES
Widgets are rebuilt on the latest WidgetKit and render properly on iOS 18 and later — no more blank or frozen ones. Put them on the Home Screen, the Lock Screen, or StandBy; Apple Watch faces can show remaining too. Each size has its own layout: small is a pair of rings — usage outside, time inside, remaining in the middle; medium and large add daily bars and your pace. Widgets sample and refresh on their own, so numbers and alerts stay current even if you never open the app.
JUST ASK
"How much data is left" and "will my data last" — ask Siri, or add them to Shortcuts. The answer includes your allowance, what you've used, days left in the cycle, and whether it will last.
THE HOME SCREEN COMMITS TO AN ANSWER
Not just a percentage. It says "on track to run out 9/24" or "enough to last the cycle," with the days left in this cycle beside the headline number.
WARNED BEFORE YOU GO OVER
Optional alerts at 80%, 90%, or when you run out — once per tier per cycle, so it won't nag. Or alert only when you're spending faster than the calendar.
TRACK AGAINST YOUR OWN PLAN DATE
Set any cycle length (a 60-day prepaid plan works) instead of only 28/30/31. Carry unused data into this cycle. Dual SIM / eSIM: both lines together, primary only, or split. And calibrate to the number on your bill.
CLEAN, AND STILL ONE-TIME
No subscription, no ads — the promo rows for other apps in Settings are gone. Dark Mode, Dynamic Type, and nine languages, including Simplified and Traditional Chinese.
