This release is about crashes. [Fixed: quit on launch] On iOS 27 devices, 4.4 would quit the moment you opened it. Fixed — if that update left you unable to start the app, this build launches normally. [Fixed: widgets stopped refreshing] On iOS 26.6 / 26.7 the system was interrupting background refresh, which also left widgets stale for days. Fixed. [Fixed: History crash] If a corrupted billing record was on file, opening History could crash the app. Damaged records are now skipped and the page opens as usual. [Also] The version number now appears in the last row of Settings, so you can read it off when reporting a problem.

Two lines, two ledgers: your secondary SIM now gets its own plan — its own data cap, billing date, and rollover — and Home pages between lines with a tap. DUAL SIM, SPLIT FOR REAL Give the second line its own allowance and monthly billing day; leftover data rolls over on its own, no longer tied to the primary line. A new segmented control on Home flips between lines, and the secondary line has its own page with daily bars and pace. ROLLING LAST-N-DAYS PLANS On a plan that limits recent usage instead of a calendar month — like the multi-day windows some carriers use? Pick a rolling last-N-days plan and the app totals the trailing window for you. Remaining shows on Home, widgets, and Siri, just like a monthly plan. SHOW USED, NOT JUST REMAINING Prefer counting up? The headline number on Home and widgets can show data used instead of data left. Tap to switch back anytime. A LEDGER YOU CAN TRUST If iOS resets its cellular counter or misses a stretch — after a restore or a long shutdown — the app spots the gap and asks you to calibrate, instead of quietly trusting a wrong number. Entering your cap or calibration now accepts your local decimal separator (1,5 works like 1.5). Widgets refresh every time you open the app. Fixed a crash in the secondary line's daily chart, and filled in missing French, Italian, and Korean text.

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.
