### 4/5 — Tape access

*2025-11-07*

If only the swapping from tape to tape were easier, I would give this 5 stars. The interaction between default & saved tapes is awkward.

### 1/5 — Unable to edit the tax rate

*2025-04-16*

I have tried several times and I not let me adjust the tax rate. This makes the app useless for me.

**Developer response:** Sorry about the problem. 

On an iPhone: scroll left by touching the 3-dot handle on the LCD line, then tap the top right corner until the Options page shows, then see the 'Set Tax Rate' button down low.

On an iPad: Touch and Hold your finger between the Tax+ and Tax- buttons on the maim display. You will be prompted to enter a new tax rate.

### 5/5 — Initial Impression

*2024-11-29*

This is exactly what I was hoping for.  It allows notes along each line entry.  It has proven intuitively easy for me to use.  Maybe after I've had more experience I might find something i don't like, but for now, I think it is great!

### 4/5 — Sales tax, limited

*2024-11-16*

*2024-02-22*

This is a powerful app!  Excellent support as well

### 1/5 — broken now, Used to be five stars!

*2023-11-16*

This app was great, fairly unique, I used it, I enjoyed it, but now it’s broken! I left a message for the developer weeks ago and it’s still broken. Too bad because I paid for the pro version!

**Developer response:** Apologies from the developer. The App has been updated and repaired. Many thanks for your heads-up. 

I never did receive a message from you.
