### 1/5 — Fraud misleading

*2026-07-23*

This app is deceptive. It advertises a free trial, but I was charged immediately. That is false advertising and completely unacceptable. If you advertise a free trial, customers should not be billed right away or misled about when charges will occur.

I am demanding a full refund immediately. I downloaded this app because it clearly stated there was a free trial. I did not expect to be charged as soon as I signed up.

I will never recommend this app to anyone. My experience has been extremely disappointing, and I consider these billing practices misleading and unfair. Refund my money.

### 1/5 — Quite useful App

*2026-03-16*

Paid for a “lifetime” and the developer rolled over to a freemium model. Dishonest marketing.

### 1/5 — Subscription fee for a calculator

*2025-12-06*

I am a hobbyist wood worker and was looking for a calculator to do fractional math occasionally. Once or twice a month. I’m not paying a subscription for a construction calculator. I would have been willing to pay a ONE time fee for a calculator. I can buy a real calculator that can complete these operations for the cost of this app. Not worth it to me.

### 1/5 — Scam

*2025-10-01*

It is a scam app

### 5/5 — No

*2025-07-12, version 2.9.25*

Jenial

### 5/5 — Math

*2025-06-28*

Quick and easy

### 1/5 — Ughhh … $39 subscription per annum

*2025-06-15*

Great potential, but I’m deleting it and will buy another app.  I’m happy to pay for someone’s hard work but $40 per year for a calculator.  WOW.   That’s insulting.

### 1/5 — Forced paywall

*2025-06-02*

Used to be great, then they forced the ONLY FEATURE WORTH USING behind a crummy paywall. Not worth downloading and they should be ashamed of themselves

### 1/5 — No free option

*2025-05-08*

Another app that says it’s free, but it needs a credit card for you to try it

### 1/5 — Ya, no to subscription anything

*2024-09-24*

I’m not ever going to pay a subscription for antilock brakes in a car, for photo editing software or a calculator. Big no.
