What started out as a “Hey, it’d be cool if my iPhone had a count down timer that spoke on intervals so I know how much longer I can fly my plane” has turned into a full featured RC model flight tracking app that I use for every flight.
eFlightJournal has that talking flight timer and as an added bonus keeps a history of your flights organized by plane, battery and location - including a summary of total flights and duration for each.
The timer screen allows you to quickly select the plane and battery and will automatically detect the location making getting up into the air a snap. It can be configured to speak the time, vibrate or play a sound on various intervals allowing you to concentrate on flying.
It also maintains the current state of batteries (charged, discharged, storage) as well as can track their charge-cycles. Batteries that require charging display the flight time on the battery (in red) since last charge.
If there is something eFlightJournal doesnt do or can do better please let me know and Ill see what I can come up with (for contact information see the eFlightJournal More > About).
Happy Flying!
