Really wanted to love this app it has absolutely everything I need in one app. But I can’t take the glitches anymore and the lack of response in fixing known issues. Started my year subscription in March and haven’t used it after the first few weeks. Especially disappointing when I reached out to support the first week I had it through the app and identified an issue with it being mostly unusable …Daily Planner, Schedule: Brite
It's a real shame that I am writing this - i wanted Brite to work out so badly. I like a lot of things about the app but various "small" or minor problems/shortcomings have caused me to decide to abandon the app. The straw that broke the camel's back is today's attempt to build a list of possible vendors for a service, call them, add notes to my list, and go on to call the next one/add notes, on a…Daily Planner, Schedule: Brite
App is great for me setting meetings, interviews, and or just daily events. However, using this with my iphone and MacBook just doesn’t like to save information to both. My computer seems to add to both while my phone doesn’t. Another gripe is I changed my email I use on my phone(which you can access actual settings on and change that) to my knowledge with a bit of looking around on the app ton th…Calendars: Schedule Planner
Question Why, in the current free version of the Calendars app, would a feature/capability like setting up a new event to repeat on a periodic basis, be “taken away from users” and only be available in the paid version of the app? This seems like nothing more than a “money grab” and an insult to loyal/longtime users, who previously had access to this functionality. This type of change makes a pr…Calendars: Schedule Planner
needs to be adjusted to ipad screens, and the app would feel better with more days able to be added in the layout if the user wants. an option for what could be the background of the calendar would be good, with a transparency option that could be adjusted. more customization options would be great, so would a small to-do list option view on the calendar. the fact that only upcoming meetings can…Notion Calendar
It’s always so frustrating when one goes to add a new event on the calendar, and when trying to add a location, the whole app freezes. I have to close the app entirely and try again, after having already added all of the details before then. Maybe have a draft feature to work around this, or… FIX THE GLITCH. This has been going on for years, so it’s not a recent issue but a persistent one.Google Calendar: Get Organized
Your rating will remain a one until you stop asking for a review every time I open the bleeping app. It’s very annoying! Why is there no spell check in the app? Creating to-do lists and the app can’t do spell check in this day and age? Why doesn’t the reminder work for the time you set individual tasks? You give the option for one single mass alert per day. Why? Those are just a few of my gr…Daily Planner, To-Do List
