### 5/5 — Perfect workout timer

*2026-07-27*

Perfect timer for workouts- keeps your music going and your screen locked while your headphones continue to play

**Developer response:** Thank you!

### 5/5 — Just what I wanted

*2026-02-11*

No ads, no nonsense, the pro version is worth the small cost, too. Thank you!

### 5/5 — Just what you need

*2026-02-05*

I love this app for its simplicity. Could use a couple more sound options though!

### 1/5 — Удалила приложение

*2026-01-25*

Я такой сама напишу за 15 мин, а они деньги берут. Ужасный таймер, не работает в фоновом режиме. Невозможно поставить серии или сеты…

**Developer response:** Да, берем, и вы напишите и берите, Товарищ Слепченко! А если вам нужен по-настоящему народный, бесплатный таймер, но при этом вполне рабочий - посмотрете на Повторный Таймер (без плюса в конце). Это полностью аналогичное бесплатное приложение, только без роскоши: нет кастомных звуков. Да здравствует Эпл!

### 1/5 — Don’t go for this

*2026-01-12*

It doesn’t have proper guide to use the app. Not at all recommended and can’t rely on this at all. Atleast hoping the app team will reach out to me in solving this

**Developer response:** Hello, my friend! I'm the solo developer of the app and I wish to add a guide, since many users request it. This is already in my todo list. I would reach it as I finish with more important tasks. Take care!

### 5/5 — My review

*2025-12-08, version 4.5*

Good app. I like it

### 5/5 — 我的

*2025-12-04*

真棒👍

### 1/5 — Useless- I paid for the app, but it doesn’t let you make the alarm go for a time of day

*2025-09-22*

It only allows the alarm to go off a stopwatch

**Developer response:** Periodic Timer is intended to send you short, repeating notifications in a sequence, acting as a repeating timer, not like a scheduled alarm. It does this single feature but in very simple and straightforward way, allowing you to quickly set the time and start alarms. Notifications with customizable sounds are delivered even if the phone is locked. The app is shipped with a collection of sounds of various intensity and duration: from subtle "tick" to various "beeps" and "annoying 30 seconds ring".

### 5/5 — Très bien

*2025-09-06*

Application bien pensée et très pratique. Petite amélioration possible : ajouter une explication sur la manière de changer de mode d’affichage pour le compteur, c’est pas très intuitif

### 1/5 — Killed compatibility with older watches

*2025-08-31*

Taking away compatibility with older watches is despicable. At least make the older version available for those who paid for it because it served a real purpose in our lives.

## Frequently asked questions about Periodic Timer +

### How does the timer work in the background?

To ensure the timer functions correctly in the background, you must allow notifications for the app. This enables the app to continue its timing operations even when it's not actively displayed on your screen.

### How can I add custom sounds to the timer?

You can add custom sounds through several methods. Files can be dragged and dropped onto the device via a computer connection, pasted into the app's folder from the Files app, shared from other applications, or selected directly using the '+' button within the app's Sounds tab.

### What are the different timer output modes?

The app offers three distinct timer output modes: intervals, total time, and countdown. You can switch between these modes by tapping the timer display located at the top of the screen.

### What is the 'Shake To Start' feature?

The 'Shake To Start' setting allows you to initiate or cancel the timer by simply shaking your device. This feature is useful when you cannot interact with the screen directly, such as during cooking, but requires the app to be open.

### How do I prevent the screen from locking while the timer is running?

The 'Prevent Lockscreen' setting is a useful option that keeps your device's screen active while the timer is in operation. This ensures you can always see the timer without the screen turning off.

## Version history (last 5 releases)

Many of my dear users looked for help, since they didn't know how to add a custom sound. Now, I believe, their problem is solved once and forever - I added "+" button to Sounds tab, making this process much more obvious and straightforward. Also, other ways of file import was tested and fixed. 

Other fixes and improves include:
- Fix bug when start button on watchOS was cut.
- Fix timer cancellation in Smart Stack on watchOS.
- Fix banners layout issues.
- Now you'll hear timer sound even in Settings tab.

### 4.2 — 2025-06-27

Dear customers and users, I return to work on this project!
Thanks for all the feedback! It was summarized and I'm fixing the most popular problems first.

iOS:

- Added new settings: 
-- Prevent Lock Screen. If ON, the screen will be up while the timer is running.
-- Shake to Start (former Kitchen Mode) - now it's OFF by default.
- Google Analytics removed. No more tracking! It wasn't very useful, anyway.

Watch:

- Vibration selection menu is now a second page, instead of the deprecated Force Touch menu.
- Fixed notification UI.
