It would be nice if the HRV was saved AUTOMATICALLY after finishing, vs having to SAVE the result. Too many times I accidently hit another part of the screen and had to re-do the test. Why not save automatically and allow the option to delete or re-do.
IF that is not possible, please at least make the SAVE button bigger and disable most of the rest of the screen inputs.
+1 this. Accidentally bumped the cancel button this morning and had to take another measurement. Saving should be automatic, and a success message should be displayed. If someone needs to delete a measurement, they can do that from the Edit menu -- but I would think that's rare.
