Now it won’t recognize my log in info and there is no Forgot Password or anything else to help, I’ve lost all my tracking and now need to find an app that actually has support. **Developer response:** Hi, Thank you for taking the time to share this — I’m really sorry for the frustration this update caused you. Losing access to your account and your tracking data is absolutely not the experience we want you to have. There was no data deletion on our side with this update. In most cases, this issue is related to an authentication mismatch (email, sign-in method, or cached session after the update). Please contact us directly at contact@reef-buddy.app with the email address you used to create your account, and we’ll help you recover access as quickly as possible. We do provide support, and we’ll make sure you’re not left without a solution. Thanks again for your feedback — it helps us improve Reef Buddy for everyone. — The Reef Buddy team ### 1/5 — Nothing happens *2025-11-24* Takes a hot minute for the home page to load. Trying to create an account but the submit button doesn’t do anything. iPhone 16. **Developer response:** Hi! Thanks for the feedback and sorry about the trouble. We’re currently investigating the slow loading on the home page as well as the issue with the Submit button. This shouldn’t be happening. Could you try closing and reopening the app, or checking if the latest update is installed? If the problem continues, feel free to contact us so we can help you directly.

Thank you for your suggestion; we will add it to a future version. ### 2/5 — Used to not require an account *2025-06-28* Was great but now requires an account to use. This is not an app that needs any of my information in order for me to track my parameters. **Developer response:** Thank you for your feedback. We understand that requiring an account may feel unnecessary for tracking aquarium parameters. The account system was introduced to enable secure data backup, multi-device sync, and future features like community sharing and personalized insights. That said, we genuinely value your privacy and are actively exploring ways to offer a local-only mode for users who prefer to keep everything offline. We appreciate your support and hope to continue improving Reef Buddy with your feedback in mind! — Shrimpy & the Reef Buddy team ### 5/5 — Awesome *2024-11-25* Easy to track and use **Developer response:** Thank for you comment!
