A warmer welcome to Focus Aquarium
• Otto now greets new divers with a gift of pearls, so your very first focus session can bring home its first fish.
• Gentler notifications: Otto only asks to send them after you've finished a session, and a friendly nudge can invite you back if you've drifted away for a while.
• Reliability improvements to Deep Focus and session tracking behind the scenes.
Thanks for diving in.
