I use a whiteboard while I'm in the reptile room and immediately record into iherp as soon as I'm done. I record sheds, feedings, weights and breeding activities. I'm pretty OCD about my records. My records are always up to date. From experience I've learned that if I don't input as soon as I'm finished then I won't input. Occasionally if I'm in the reptile room for an exceptionally long length of time I'll bring in my laptop and input straight into iherp. The only thing I record on spreadsheets are my planned breedings and potential outcomes.
Regards,
