It does not change notification settings in the Gmail app. To avoid getting two notifications for the same email, turn off Gmail app notifications for each account you monitor with Owl VIP. PRIVACY AND GMAIL ACCESS Owl VIP uses Google Sign-In, so your Gmail password stays with Google. Owl VIP requests only the Gmail access needed for the features you choose. Standard notifications use Google’s metadata-only Gmail permission to apply your rules and deliver notifications. This includes basic details such as the sender and subject, but not the email body. If you turn on optional snippet previews, Google will ask you to allow read-only access so Owl VIP can include preview text in your notifications. These permissions do not allow Owl VIP to send, change, or delete your emails. Owl VIP does not save email content in its database. SUBSCRIPTION PLANS Owl VIP is free to download. A subscription is required to connect Gmail and use Owl VIP’s email-notification features. Eligible new subscribers receive a 7-day free trial. After the trial, the subscription renews automatically unless canceled. Choose the Single Inbox plan to monitor one Gmail inbox, or the Up to 3 Inboxes plan to monitor as many as three Gmail inboxes with separate settings. Google Workspace access may depend on your organization’s settings. Owl VIP is not affiliated with Google LLC. Gmail is a trademark of Google LLC.

Both are free to download. MantisApp sells 7 in-app purchases, starting at $0.99 per month and Owl VIP Email Alerts sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Owl VIP Email Alerts holds the better App Store score, 4.3 against 2.3. Both are backed by a comparable volume of ratings — 3 and 6 respectively. Written reviews complicate that: 29% of MantisApp's written reviews are positive against 0% of Owl VIP Email Alerts's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
