### 3/5 — Broke

*2026-07-02, version 2.3.0*

My favorite and most used app updated and now does nothing. 

I missed so many notes because they just never arrived. 

Was 1,000,000 out of ten. Now 3? Maybe they will fix.

### 5/5 — Two taps to share

*2026-06-20, version 2.3.0*

The best thing to send almost anything shareable to myself for follow up. Can’t recommend enough. Do yourself a favour and install this app. Send some love to the developer, they deserve it.

### 5/5 — Saves sleep

*2026-06-18, version 2.3.0*

This thing saves me so much sleep when I wake up with a thought for work or something to do personally the next day or throughout the week. I used to write it down in a notebook but this is so much faster. Paid for the 2nd email and could not be happier! 
The Yoyo rebrand threw me for a loop but this is one of the best apps I’ve ever had!! Cannot recommend it enough!

### 5/5 — Simple and useful

*2026-06-18, version 2.3.0*

What a beautiful example of a simple and useful application. No bloat, no confusion, no piling on of unneeded and unnecessary features. It does what it says it will do simply, effectively, and beautifully. I use it many times over the course of a single day.

### 5/5 — Großartig

*2025-11-27, version 2.2.1*

Die beste App im Universum! Und genau das was ich gesucht habe; schnell, einfach, genial. Wenn es ging würde ich einen 6ten Stern vergeben 😀 Bitte ipad- Unterstützung nachreichen.

### 5/5 — ora è ok!!!

*2025-08-13, version 2.2.1*

👍👍👍

### 5/5 — Seamless

*2025-07-31, version 2.2.1*

Much better than the alternatives and I’ve tried them all.

### 5/5 — Very useful

*2025-05-12, version 2.2.1*

Essential, I have been using it everyday for many years.

### 5/5 — Excellent

*2025-04-27, version 2.2.1*

Excellent et gratuit. The perfect tool

### 3/5 — Plötzlich kostenpflichtig

*2025-04-13, version 2.2.1*

Gute App. War eine gute und zuverlässige App. Leider wurde nun die 2. Emailadresse über Nacht kostenpflichtig. Schade. 
Leider ist der Preis auch viel zu hoch, sonst hätte ich es vielleicht mir auch überlegt diese App zu kaufen. Schade.

# The second email is now a paid feature.

As Boomerang welcomes more and more users, the maintenance of the app has become costly. To sustain development, I have decided to make the second email address feature a paid option. It's a one-time payment; I hope it's affordable for everyone. Please share your feedback with the form inside the app. Thanks for your support!
