## What is Silo?

Silo is a Pomodoro-style focus timer built for Apple Watch and iPhone.

It uses subtle wrist haptics to guide focus and break sessions without loud alerts, distracting notifications, or constant phone checking. Perfect for students, people with ADHD, deep-work professionals, and anyone who wants a calmer way to stay on track.

Silo is especially powerful on Apple Watch: a tap on your wrist tells you when to focus, when to take a break, and when to return. It’s ideal for libraries, offices, meetings, and anywhere silence matters.

“To add something to your daily life without intrusion or complication—that’s what the Apple Watch is about, and this app does a great job of that.”
— Apple WatchCast Podcast

### 1/5 — Restore not working

*2024-12-15*

Restore purchase link not working when tapping it, a trick to buy again the app??

**Developer response:** The app is no longer a subscription purchase—it is a one time payment.

### 3/5 — Great app but complications not working

*2024-07-27*

Testing the app it seems great, but after upgrading to Pro, restarting the Apple Watch and the IPhone I still can’t configure the complications in my Apple Watch

**Developer response:** Please update your watch and phone, it should now be working.

### 2/5 — Complications not appearing?

*2023-01-14*

Really want to like this app, but after upgrading to Pro, I still don’t see any complications available to select on the watch face screen?

**Developer response:** Hi, were you able to get this resolved? It may take a couple of minutes for Pro to show on the watch. If you still have trouble, please reach out: 
support@silofocus.com

Also if it worked, if you would kindly update your rating / review. Thanks!

### 4/5 — One the better pomodoro apps when it works

*2022-12-12*

So far, I really like this app. The look and functionality is great. But I find that I’m not getting notifications at the end of sessions. Often, I’ll go to check how much time is left in a session only to find that it ended a while ago and I wasn’t notified. :(

### 5/5 — Feedback

*2022-10-26*

- the way the subscription is present is a turn off. Find a way that is less frustrating to new users. I spent 5 minutes trying to figure out the features only to realize they can’t be interacted with at all. I thought the app was broken.

- add a numerical timer. I like the aesthetic, but I also like to know the exact time left.

- sync the Apple Watch and iPhone app. I set a timer on one, the timer should be going on the other. That’s the deal breaker for me, personally. 

Giving five stars because previous reviews are unfair and this app is one of the better pomodoro apps I’ve tried, just dragged down by its subscription presentation and the lack of a numerical display. It’s been more than a year so an update is unlikely, but I hope you consider the above if you do update it.

### 1/5 — Doesn’t work

*2022-09-12*

You set the timer going, that works. But once it reaches the end you get no notification or vibration on your watch and the app seems to close. When you open it back up again it resets the timer. You’d think for a simple concept it should be easy to get right. Avoid

**Developer response:** Hey, sorry about your bad experience. Please email contact@silofocus.com — I’ll be happy to troubleshoot this and offer you a promo code for your trouble.

### 5/5 — Great watch app

*2022-06-28*

Free version is great and met all my Pomodoro needs!

### 1/5 — Subscription trap

*2022-04-10*

No complications without a subscription. 

No sync between watch and phone. 

One star. I don’t like “creative” descriptions that avoid the truth.

### 1/5 — Бред

*2022-02-04*

Забавно, заплатил за приложение. А теперь еще про функции за подписку.Вы серьезно?

### 1/5 — Waste of a dollar

*2021-12-13*

I purchased this app for a dollar, and as soon as i opened it, it wouldn't let me do anything taskwise unless i pay for a monthly subscription! Plus, the pomodoro timer does not show you the current time (not even sure if its working), and if you pause the timer, you're not sure if you're actually pausing or resetting the timer. Very Frustrating!

**Developer response:** Sorry for your bad experience. It should say “paused” when the session is paused. I’ll do my best to make the experience better. Also will be happy to send a refund for your dissatisfaction.
