[Function Details]

■ iOS Calendar
This app uses the iOS calendar app. Schedules made with this app will be synchronized with other scheduling apps and the iOS standard calendar.

■ Adjust Font Size
You can choose from five font sizes of extra-small, small, medium, large, and extra-large.
You can also pick between light and bold font, to make prioritized events pop up better.

■ Monthly, Weekly, and Daily Calendar
With one tap at the bottom of the screen, you can switch between monthly, weekly, and daily display.
Switching the weekly calendar between 7, 5 or 3 day display allows you to find the display that is right for you.
The app memorizes the calendar style used the last time you opened it, making it super convenient for people who only want to use the weekly display.

■ Color Coding
You can create separate calendars according to different schedules, such as work and home. Then, you can manage them clearly by color coding them. You can switch the background color between white and black as well.

■ Secure Passcode Lock
You can securely lock the app with a password if you don't want anyone to view your calendars. Of course, you can also lock with Face ID and Touch ID as well.

■ Notification Settings
You can set up notifications for scheduled events at the event time, as well as 5 min, 15 min, or more prior to the event, so you don't miss important plans!


[Note to Users]
Since this calendar app uses the standard function of the iOS calendar, all schedules older than one month may disappear with the default settings. This also applies to other apps. If you want to keep past events, please follow the procedure below after installing the app.

1. Open the iOS Settings app.
2. Tap "Calendar".
3. Tap "Sync".
4. Select "All Events".

This should solve the problem.
If you still have questions, visit the "Help/FAQ" page in the app for further details.


【Help/Inquiries】
Please visit "Help/FAQ" from the settings screen of the app. If this doesn't help, please contact us through "Inquiry / Feedback" from the settings screen. We can respond to you much quicker this way, so please do so instead of asking us questions in the app review, since it takes a while for those to be reflected onto the page.

### 1/5 — Add events only NOT sync

*2026-08-10, version 5.8.0*

The ability to add events ONLY does NOT work. It’s will try to open settings continuously to push user to allow full access.

### 1/5 — Слетает

*2026-08-05*

Больше 2-х лет пользовалась и все было отлично. Но последние 2 месяца все мои события слетали. Сама нашла как восстановить, но сегодня все снова слетело и восстановить не получается, так как ори и оттуда пропали. Очень расстроена, придется все восстанавливать и искать новый планер

**Developer response:** Приносим искренние извинения за доставленные неудобства. Благодарим вас за то, что пользуетесь приложением более двух лет. Симптом, при котором события регулярно исчезают, чаще всего возникает, когда в настройках iPhone ограничен период синхронизации календаря (приложение хранит события в стандартной системе календарей iOS). Пожалуйста, откройте «Настройки» → «Календарь» → «Синхронизация» и выберите «Все события», затем через некоторое время проверьте приложение. Также возможно, что события скрыты из-за настроек отображения — подробности в статье: https://simpleapps-calendar-ios.zendesk.com/hc/ru/articles/900005623103 Рекомендуем также проверить, достаточно ли свободного места в хранилище устройства. Если проблема сохранится, свяжитесь с нами через [Связаться с нами] в верхнем правом углу на экране справки в приложении — мы обязательно разберёмся в ситуации.

### 4/5 — вопрос

*2026-07-29*

как поменять чтобы у меня месяц  был не цифрой а названием ?

**Developer response:** Благодарим вас за отзыв. К сожалению, в настоящее время в приложении нет настройки, позволяющей отображать месяц названием вместо цифры. Мы примем ваше пожелание во внимание при дальнейшей доработке приложения. Благодарим вас за использование нашего приложения.

### 1/5 — Не советую

*2026-07-21*

Заполняю на месяц все события, ни с того ни с чего слетает постоянно уже все, все стирается ! Удаляю! Не советую!

**Developer response:** Приносим извинения за доставленные неудобства. Возможно, события были скрыты из-за настроек отображения.

Также рекомендуем проверить, достаточно ли свободного места в хранилище устройства. Приносим извинения за неудобства и благодарим за обращение.

### 1/5 — Please Fix!

*2026-06-24, version 5.8.0*

I’ve had this app for a few years, I love it it’s been great. But now there is a bug that won’t go away. It’s adding days/week long “events” scams to my calendar and I can’t delete them they just come straight back. Please fix this so I can continue using the app.

### 1/5 — Privacy problems

*2026-06-06, version 5.8.0*

I’ve found that spam events are finding their way into my calendar, events I haven’t put in there such as “claim my free WiFi router” etc etc with dodgy links. If these spam companies can put their data on my calendar then I wonder what data they can also take from my calendar. Deleted

### 1/5 — Apagar os dados

*2026-06-01*

Eu gostava muito do aplicativo porém já tem um tempo que ele vem apagando os dados dos meses passados e eu perco todas as anotações

**Developer response:** Pedimos desculpas pelo transtorno. É possível que os eventos estejam apenas ocultos nas configurações, por isso pedimos que verifique a seção “os eventos desapareceram” na ajuda: https://simpleapps-calendar-ios.zendesk.com/hc/pt-br/articles/900005623103

Além disso, nesse artigo também explicamos como usar a função de “restaurar eventos”, disponível a partir da versão 5.8.0, que pode permitir recuperar vários eventos de uma só vez.

Pedimos desculpas pelo incômodo e agradecemos se puder verificar.

### 1/5 — Up until today

*2026-05-27, version 5.8.0*

Why all of a sudden I have Asian words and numbers in my simple calendar? I wish I could speak Asian language but I can’t so what’s happening to my Simple Calendar
