Recording and sending voice memos made easy! Voice memos are a great way to quickly capture some ideas and send them to your own or someone else's mailbox. Unfortunately this usually requires a lot of steps until you are done. Until now. 4Memo provides you with a workflow that uses the least possible steps in order to record a voice memo and send it to whoever you want while protecting your privacy. Just enter up to four recipients to which you can send your voice memo as quick as possible. Those recipients will appear as big, easy-to-hit buttons on the app's main screen. After recording your memo, just hit the respective contact button and your voice memo will be attached to a prepopulated, ready-to-send email. Just on more tap on "Send" and your message is on its way. And the best thing: You can now do that also from your Apple Watch and via Siri Shortcuts! (Paid premium features) We developed 4Memo with your privacy in mind. Therefore, there is no data transmitted to our servers nor is it in any other way processed on your device. The recording and processing of your voice memo is completely and solely done on your iPhone. The email is sent via the mail account which is configured on your device. This means that it is sent solely through the servers of the email provider of your choice, just like any other email that you send through the iPhone's mail app. This makes the final tap on "Send" necessary but it also asures you that all your data stays in your hands all the time.

Verdict

The call

The clearest difference is review sentiment: 4Memo at 77% against MantisApp's 29%. MantisApp's advantage is price (Free vs $0.99) and rating (2.3 vs 1.0). On update cadence, ads, in-app purchases and device support there is nothing between them.

MantisApp is free to download; 4Memo costs $0.99 up front. MantisApp sells 6 in-app purchases, starting at $0.99 per month and 4Memo sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

MantisApp holds the better App Store score, 2.3 against 1.0. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 29% of MantisApp's written reviews are positive against 77% of 4Memo's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

MantisApp ships an update every 2 months, 4Memo every 3 months. Both last shipped on November 1, 2026.
