“I’ve been using Brite for over a year now as a Premium Subscriber, and although I’ve loved all the features it’s offered, I’ve had many glitches. For the past few days I’ve not even been able to access anything on the app, including my profile settings. I’ve installed the latest update and reached out to customer support a couple days ago but have been waiting to hear back. I have several critic…”Daily Planner, Schedule: Brite
“Used this app for years and paid for premium and it gets the job done but still lacks some basic features like a search function. Becoming more and more difficult to get around needing a search function. Have requested the feature several times over the years and always get the same, well think about it answer but the devs just will not prioritize an easy way to find tasks. Have to manually open …”Tody
“This app COULD be good. It’s a good idea, and it has quite a few potentially-useful features. Sadly, it’s really not good. It’s fille with bugs, there are numerous pointless and avoidable shortcomings, and many of its most unique features didn’t have the user experience fully thought-through. First, there are numerous shortcomings. For example, anytime you write something that it THINKS is a loca…”Calendars: Schedule Planner
“As a neurodivergent, adjusting to the changes in our necessary technological utilities, I have felt abandoned, and constantly on a fools journey. First and foremost prerequisite to be costly. While everything becomes itemised, the digital landscape is loud, over complicated, and unfamiliar. This app has given me the visual silence, the mental shelter for one’s sovereignty with one’s UX interface. …”To Do List MinimaList & Widget
“I'm so sad to admit I can no longer use or recommend this app! I've been using this app for almost 2 years. It was a life saver as a new business owner, and I've relied on it HEAVILY to keep my life straight. Until last weekend when the switch back to Standard time took place. I had the app open when the time switch took place and it apparently caused some sort of glitch where I couldn't see an…”Focus To-Do: Focus Timer&Tasks
“I’ve had this app for years, I got in while they had a lifetime pro deal going on. They have typically been very responsive to letting them know about problems but it’s been over a year of the app not working with my Apple Watch. It always says no events for today, no matter how many are on my calendar. A couple months ago I reached out over a different bug, when I change the date of a recurring e…”24me: Calendar・Planner & To Do
“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
