### 5/5 — It really works!

*2025-08-31, version 4.02.00*

Great app. It’s just like using a 10-key with paper tape. I use it all the time. Update 8/31/25: still great. If you start seeing incorrect totals just close and reopen the app. It only happens when I use it for many hours.

### 5/5 — It really works!

*2024-09-08*

Great app. It’s just like using a 10-key with paper tape. I use it all the time.

### 5/5 — An Oldie But Goodie

*2024-04-02*

I think I first installed this at least 10-12 years ago. Simple, easy to use, but capable of more complex uses. Does what it says it does. 

It seems it’s no longer being updated. I just want to give credit and thanks to the developer.

### 2/5 — Info and Settings wheel CLOSES APP on iPhone

*2024-04-01*

I downloaded APP on my tablet and all the settings and buttons work fine, I’ve updated my IOS to 17.4.1 for my iPhone and the moment you attempt to use the INFO and Settings wheel (to Manage Paper tape), the APP instantly closes. 

Again, works fine on the iPad running the same IOS 17.4.1

### 5/5 — Perfect calculator

*2024-03-26*

Does everything well, very intuitive.

### 5/5 — Owner apt complex

*2024-01-09, version 4.01.00*

I work’s like you said.

### 3/5 — Seems good but can’t get question answered

*2023-11-16*

The calculator seems to work great and I love the tape but it is only allowing me a few lines of tape???

### 5/5 — Great calculator

*2023-06-19*

Great but if you make a new version it would be awesome if you add a column for references.

Example

Diamonds      1,000
Setting            150
Polishing.        60
Total.               2,210.00

### 3/5 — Use to work well but print no longer working.

*2023-03-15*

I always used this app in the past for my income tax prep… adding up gas receipts.  Print function no longer working.  App simply shuts down on my iPhone losing all entries.  I am using current iOS .  Must be incompatible with newer iOS updates.

### 1/5 — Abandoned product

*2022-12-02*

Doesn’t work well on iPads or any newer devices 

Loved this app but can’t use it for what I need anymore
