### 1/5 — Paid for the app….now want me to pay again.

*2025-06-26, version 3.3.1*

I bought this app several years ago for $5 on the App Store…. Now there’s an update asking me to pay AGAIN yearly or $18 for life… when I paid initially. Total scam and joke of an app greedy developers

### 1/5 — Rip off

*2025-05-18, version 3.3.1*

I actually purchased this app outright sometime ago and it works quite well. 
Suddenly they decide to renege my purchase and pressure me to pay for a subscription or purchase the app again at an inflated price. 
Imagine buying something from a store then having the store owner chase you up years later for more money because they’re prices had gone up. 
Quite an aggressive tactic IMO.

### 1/5 — Purchased then bait and switch to subscription model now they want more money

*2025-02-15, version 3.3.1*

Don’t buy this garbage timer or they will try to make you buy it again.

### 4/5 — Ruined

*2025-02-07*

After paying for this app many years ago, they have now decided to go to a subscription model and previous purchases are not supported. Money grab.

**Developer response:** Sorry to hear you’re having issues, if you previously purchased the app you should not be asked to pay again. Send us an email at info@bittimer.com and we’ll get things sorted out.

### 1/5 — Payment again?!!

*2025-01-07, version 3.2.3*

I purchased this app years ago and now they’re asking for a monthly fee. I’ll use my $30 digital watch that doesn’t have a subscription fee. I enjoyed this app for years but all good things come to an end.

### 1/5 — Changed payment

*2024-10-02, version 3.2.3*

They charged for the app upfront, and then later put a paywall after using it, requiring this app’s longest serving users to double pay. There is no customer support or ability to communicate with these people.

### 3/5 — Subscription?

*2024-09-03*

Has been my go to app for simplicity although I use others for more complex treatments. I just don’t see how a subscription model justifies a simple timer app. Paid before but I just can’t anymore. Best of luck to this new sub model but not for me.

**Developer response:** Sorry to hear you’re having issues, send us an email at info@bittimer.com and we’ll get things sorted out.

### 1/5 — Purchased the App & Now it Requires Subscription

*2024-07-25, version 3.2.2*

I purchased the app before but now it will only give you 5 timers and then it requires a subscription. I submitted a ticket on the website and there has been no response.

### 1/5 — A subscription for timers

*2024-05-31, version 3.2.1*

I just can’t imagine anyone justifying the concept of a subscription for a timer app.

### 1/5 — I downloaded a lifetime membership

*2024-05-30, version 3.2.1*

Now it says subscription required.  Loved the app but not the changes. Tried to restore purchase and it won’t let me.
