About

Feno

Features
Read full description

Feno is an AI chat for reminders, shopping lists, and photos. Talk to it like a person. “Remind me tomorrow at 10 to call mom.” “Add milk, bread and eggs.” Feno files the reminder and puts the items on your list — no extra screens, no date pickers. Send a photo when typing is slower. A concert poster, a receipt, a note on the fridge. It lands in the chat, and you can turn it into a reminder, a shopping item, or keep it as a note. Busy hands? Hold the mic and speak. Feno writes it down. Reminders sit behind the bell. The shopping list is one tap away. One conversation instead of five apps. No account. Nothing is sent off your iPhone. Chat, photos, reminders, and lists stay on the device. Feno is free to download. Feno Pro is an optional auto-renewing subscription. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of that period. Manage or cancel anytime: Settings → your name → Subscriptions. Cancel stops the next charge; the time you already paid for stays active until it ends. Any unused part of a free trial is lost when you buy a subscription.
