I wrote these mainly for my own use, but took the time to productize them, so charge for them. That said, I like them being used and doing good, so if their price is a barrier, here is an opportunity to try them for free…
Timestamped Field Notes:
I use this myself for Raptor Monitoring taking timestamped notes when trying to keep binoculars on Peregrine Falcons, Prairie Falcons and Golden Eagles. Some use ethograms with primates, spiders, and more. It has been used for observation notes for everything from humans to whales and many more. Some use it for taking health log notes. The application is iOS only, but it is free for the month:
I wrote this for wildland firefighting (locating smoke columns in the mountains) but a number of wildlife biologists use it for radio telemetry triangulations. Take two points plus compass bearings to a destination point and it calculates the latitude/longitude estimate for that point: iOS and Android, and free on IOS for the month, on Android for the next week:
Android Field Triangulate has historically stored events (collections of readings comprising a triangulation) in memory. The intention was to create a few readings (in a relatively limited timeframe) and create a triangulation. Job done, triangulation shared. In actuality this isn’t how things always work, and wasn’t always sufficiently reliable.
Despite attempts to save these readings to instance state, in memory storage could lead to lost data … say if the application is unloaded (e.g. by a battery saver killing applications.) Lost data is never good, and this was never the intention.
Note: The reason for network connectivity at first setup is because the persistent store utilized is a cloud synchronized database. In theory (given a named account) this could be used to synchronize events (readings and triangulations) between devices. Please contact me if that seems of interest.
BTW: If/when asked for location permissions, Android Field Triangulate doesn’t need more than “Allow only while using the app”.
