Your Watch battery, in view. WristBattery brings your Apple Watch's last measured battery level, charging state and measurement age to iPhone. FREE EVERYDAY FEATURES โข Battery level, charging state and measurement details โข Basic low-battery reminders below 75%, 50% or 25% โข Interactive charging history, monthly view and estimated charge cycles โข Separate names and histories for saved watches โข Home Screen and Lock Screen widgets and a Watch complication โข Optional charging Live Activity and private iCloud backup โข Siri and Shortcuts for saved battery readings โข Guides, FAQs and an on-demand system check Quick access through Overview, History, Planning and Alerts. PREMIUM: PERSONAL CHARGING PLANS How long might your battery last? Planning shows remaining battery life and, separately, time until your daytime reserve. Ranges and explanations are available in details. The local model uses your discharge periods for each Watch. Recent comparable data receives greater weight; time-of-day patterns need enough observations. Saved predictions are compared with later suitable readings. Inspect periods used, exclusion reasons and the quality record. Optional night planning helps you decide whether to charge before wearing your Watch overnight. Morning time and desired remaining battery are independent of daytime reserve. A dedicated night profile needs three sufficiently observed nights; otherwise the general data basis is identified. An evening hint is a separate opt-in. No sleep tracking or import of Apple's sleep schedule. Restart daytime learning, overnight learning or both for each Watch. Older readings remain in history but do not rebuild the reset pattern. Settings and consumed notification limits are retained. Data controls remain accessible without Premium. Personal rules remind you about low battery, charging start or a target level. Choose watches, weekdays, time windows, quiet hours and limited repeats. Basic and personal reminders work independently. A charging target does not stop charging. PREMIUM WITHOUT A SUBSCRIPTION Open the crown icon or Settings > Premium. Eligible users can try Premium free for seven days, once per Apple Account. No renewal or automatic charge. Permanent Premium is a separate one-time Apple in-app purchase at the Store price. Existing permanent purchases remain valid. Basic features stay free after the trial; Premium settings are retained. LIVE ACTIVITY AND SYSTEM LIMITS The free charging Live Activity is off by default. Start it in the app or deliberately through the native Shortcuts action with a fresh saved charging reading. Optional automatic start runs while the app is active and a fresh charging reading arrives. Manual dismissal is respected. Automatic start while the app is closed is not guaranteed. The Watch supplies its own readings. The public watchOS value may be rounded and differ from Apple's display. Apple controls background execution, transfers, widgets and notifications. Refresh cannot force the Watch to wake. No guaranteed real-time updates. Forecasts need Premium or an active trial and enough recent data. Fresh observations are collected locally even without Premium. More data does not guarantee narrower or more accurate estimates. Forecast reminders are optional and separate from measured-threshold alerts. Estimated cycles are not Apple's official cycle count or a battery-health measure. LOCAL AND PRIVATE No WristBattery account, developer server, advertising or tracking SDK. Forecast data, learning start dates, quality records and settings stay local, outside private iCloud backup. Device-backup exclusion is requested, not guaranteed. Imported history does not train forecasts. No external AI. A sanitized forecast report is previewed and shared only at your request. Requires iOS 17 and watchOS 10 or later. Siri availability depends on device, system and language.

Verdict
The clearest difference is in-app purchases: Alarm Max at none against WristBattery's 2. Alarm Max also leads on iOS requirement (15 vs 17.0). On price, ads and device support there is nothing between them.
