The best feature about upviser is that it provides me with all of my client's information at one place which makes things so much easier for myself as well! I dislike how sometimes when i try to edit an entry or add new entries into this app everything will freeze after awhile until you refresh your page/tab then its fine again but not really something thats easy enought o just overlook. Make sure u set notifications accordingly because if they arent updated right away there can be some lag time before ur notified (also depends what kindof notification mode).
