These three apps get compared often because they represent three different philosophies for what a therapy companion app should do.
Wysa is built around 24/7 availability. Its strength is being there when you need to talk and nothing else is open. Its limitation is that most conversations don't carry much memory forward, so you're often starting from scratch.
Ash is built around memory. It can reference things you told it weeks earlier, which makes it feel more continuous than Wysa, but it's still a standalone companion, not connected to any therapy you're doing with a real person.
Symplia is built around a different question entirely: not "what can I talk to right now" but "how do I stay connected to what I'm actually working on in therapy between sessions." It's a therapy companion app in the literal sense, meaning it's designed to complement real sessions with a licensed therapist, not replace or run parallel to them.
Which one fits depends on what you're solving for. If you want a friend to talk to anytime, Wysa. If you want an AI that remembers your history, Ash. If you're already in therapy and want the time between sessions to actually reinforce that work, Symplia is built specifically for that gap.
