About chdv
If you connect a device to its charger, do you know when enough power has been charged? Or do you look at the battery display from time to time, too?
And how many times have you forgotten to disconnect charging devices from the charger?
chdv (Charging Devices) creates reminders for all your household devices when you recharge their batteries: Your GPS, hair clippers, razors, bicycle lamps, vacuum cleaner, wireless earphones... and of course your iPhone and iPad.
Never forget to unplug the charger in time!
chdv can also tell you when it's time to recharge a battery that you could forget about. For example, the old cell phone in your closet or wireless headphones. In this way, you can prevent the deep discharge of batteries and ensure that devices are ready for use.
Starting in v1.3 chdv can manage the power status of HomeKit compatible outlets. That means: You plug in your device and go to bed. chdv uses HomeKit automation to turn off your outlet. :-))
chdv synchronizes all information via iCloud. So you only have to maintain all data on one device.

+ Improvements to layouts and labels - for a better usability
- Removed an experimental option for HomeKit, as it was no longer needed
Logic adjusted:
* For some reason, you might really want to only save the time of a recharge. So, even if a setup shall not create a reminder and HomeKit automation, chdv now stores the time anyway.

+ Added a new screen that explains the idea
+ Changing the interval for "proposed recharge" now uses the last known charge date as reference date

* Fixed a bug where the app could crash when tapping "Calculate and remind me"
* List elements that navigate to a subordinate list are displayed with increased contrast
