Powerdiary is extremely user-friendly and efficient - it constantly blows me away! I have to say that the initial set-up process was labour-intensive. Also, because it's so customisable there are some parts that took some getting used to (e.g. session packs). However I received lots of support and answers to all my questions. I now LOVE using it. It saves me so much time each day and there are additional services I now provide which clients love, such as appointment reminders, emailed invoices and medicare claims. Things I'd love to see in future: easier access to phone support even if just for the initial month, and I'd love to see an android mobile app developed.
