## What is Anti?

We have prepared three functions to deal with molesters immediately when you are molested.

(1) Sound
A ringtone is used to deter molesters by attracting the attention of those around you. Since it is not a buzzer but a ringtone, it is easy to use even in cases where you are not sure (but suspect) that the person is a molester. The sound can be played from the iPhone's speaker even in silent mode or when headphones are connected.

(2) Sign
You can display a message on the screen to notify people around you. Messages can be freely edited.

(3) Telephone
You can register emergency contact numbers, such as the police or family members, so that you can contact them without panicking.

If you have any suggestions about this app or ideas for improvement, please let us know in the review section or to App Support.  We are always grateful for your feedback. We hope this app will be useful to you and you can live with peace of mind.


## Version history (last 5 releases)

### 3.0 — 2023-03-18

Thank you for always using us. In this version, we have released the following 3 features that were previously premium features so that anyone can use them.
(1) Theme color setting
(2) Display of pseudo incoming call screen
(3) Extended the maximum number of registered contacts to 100


Since iOS 16.2, the specification has been changed so that AirDrop will not be received from people who are not registered as contacts. Therefore, the effect of the message function using AirDrop has disappeared. We don't know how the iOS specifications will change in the future, so we are leaving the AirDrop message function just in case, but we hope you can use "Sound" and "Sign" as a countermeasure against groper.

### 2.3.1 — 2022-10-03

- The maximum number of contacts can be registered has been increased.
 - Fixed a crash when copying and pasting new contacts.
　Please delete the application and install it again from the App Store on the device where this bug occurred. We apologize for the inconvenience. Thank you for contacting us regarding this issue.

We welcome your comments and suggestions. Thank you very much.

### 2.3 — 2022-09-29

・Increased the number of types of fixed phrases for AirDrop messages in response to suggestions.
・Fixed the following 4 problems caused by iOS16.
　1. Minor layout collapses fixed
　2. Fixed the issue of the registration sheet for new contacts closing unintentionally
　3. Fixed a bug in which the application share screen would close unintentionally. 
　4. Disabled the "Keep a record" function because it caused the app to crash when it was selected
If you have any comments on these changes or suggestions for improvements to the app, please contact App Support. Thank you.

### 2.2 — 2022-07-16

Icon design has been changed. We have changed the design to be more visible than before, making it easier to find the app on the home screen.
If you have any comments on the changes or suggestions for improvements to the app, please contact App Support.
Thank you.

### 2.1 — 2022-07-10

Thank you for your feedback.
This time, we have made the following improvements in response to your opinions and requests.

(1) The Sound function has been extended.
Added the sound source of the security buzzer. Other sound sources have also been renewed. In addition, a volume slider has been added. You can now manually adjust the volume.

(2) The acquisition timing of location information has been changed.
Until now, the current location was automatically acquired when leaving a record of sending AirDrop messages, but in this version, a button for acquiring the current location has been added. This will only get your current location if you press the button. If you allow the use of location information, you can save your current location in the record, but you can use the basic functions of the app without any problem even if you do not allow it.

(3) The display name of the app has been changed.
To make it easier to find the app on the home screen, the display name of the app has been changed to "Anti-Groper". You can open it immediately by typing "Groper" in the search on the home screen. In addition, it has been pointed out that the visibility of the icon is poor, so this will be changed in the next version. I hope you can wait for a while.

We would appreciate it if you could continue to give us your opinions, including the improvements made this time.
Thank you.
