Caveat
If I had to work on such a project in a real situation, there are three steps I would do before starting any design, which I believe are the keys for a good design. That is why I took the freedom to explain them here, in order to show my process, mention the hypothesis taken, and point out the question that remains open:
Defining usage
Understanding the current usage is key during a redesign to not disappoint the user base. For this test, I quickly read ratings and reviews from the store, and check how users take their BeReal. Unfortunately, without a deeper analysis, only wrong assumptions can be made.
At least, my observation is that the level of satisfaction is significantly different between Android and iOS, where a lot of frustration comes from Android users. It's unclear at this level of research if it's related to the taking-picture process, but it could be, as part of the frustration is related to the time to take a picture and notifications. It leaves a question open on how we want to handle Android’s design?
My hypothesis is that BeReal users use the delay between both pictures in order to trick the camera process and get pictures in other angles than selfies. It lets an existential design question open: should we emphasize this behavior or try to come back to a more "real" double picture?
Defining scope
What is the exact technical scope that the redesign takes into consideration? I observed that iOS and Android have a feature gap, which opens a question on what has to be considered for both platforms. It's also unclear on my side which is the current app scope, as I have Android. It seems that iOS can take video, but Android cannot.
Defining goals
Without goals, it becomes challenging to evaluate whether a design is truly good. Often based on the technical scope, usage, and business goals, they must be defined to determine how good the design is. For instance, if the goal is to reduce the number of retakes, minimize frustration among Android users, ensure timely BeReal submissions, or emphasize or discourage usage that tricks cameras, the design must align with these objectives.
