We have received your details, and our team is currently working to verify your account so you can log in and redeem your payment as quickly as possible. We appreciate your patience while we wrap this up! ### 1/5 — Bad start *2026-04-26, version 3.6.13* Why would you make me create my account AGAIN because the confirmation email went into my spam, and it expired because I didn't see it? Why not use the creds I already spent time inputting to create the account, rather than making me start from scratch? I haven't even started using this app and I'm already annoyed. I'm a software developer myself, and I cannot believe the way other devs abuse their users with bad design like this. ### 1/5 — No reward for my survey *2026-02-11* No reward for my survey **Developer response:** Thank you for the feedback. Please note that while ExpiWell hosts the surveys, rewards are managed independently by the researchers. To inquire about your status, please use the 'Contact' email function found under 'Experience Options' within the app. The researchers are responsible for project compensation and are best positioned to assist you. ### 5/5 — Straightforward *2026-01-27* The ExpiWell experience was intuitive.
