*2023-05-14*

### 1/5 — Scam

*2023-03-27, version 1.5.0*

This app is a scam and you can’t get nothing

### 1/5 — Don’t buy

*2023-02-06*

Useless application

### 1/5 — Not great.

*2022-11-23*

I paid extra for “all access” but nothing more to see here! I thought I’d get a diagram that can be found for free on the Internet. So, not with the $$.

### 1/5 — Don’t waste your time

*2022-06-11*

App requires both rise and run I order to calculate specs. Rise is easy. Why is the app requiring a run input in order to provide specs? The whole purpose of app is to determine run, dumb app

### 1/5 — Don’t do it

*2021-11-07, version 1.5.0*

This is terrible

### 1/5 — Stupid

*2021-08-23*

I’m having a bad user experience.

### 1/5 — Interupted!!!!!!

*2021-05-18*

I don't want an app where I have to listen to an ad every stinking time I calculate a run!!!!

### 1/5 — Paid for Blueprints and never got

*2021-02-23*

I paid via Apple and they were supposed to be emailed to me. Never got them. Even checked junk email.

### 1/5 — Nul

*2026-03-09*

Ça m’a pris l’abonnement sans la période d’essai. C’est juste un très simple calculateur pour un escalier droit. Pas besoin de payer, une calculatrice ferait la même chose. Il ne permet pas de faire d’autre type d’escalier  !

**Developer response:** Bonjour,
Merci pour votre retour.
L’application propose normalement une période d’essai gratuite avant le paiement pour les utilisateurs éligibles. Toutefois, un essai gratuit peut ne plus être disponible dans certains cas, par exemple lorsqu’il a déjà été utilisé auparavant avec le même compte.

L’application est actuellement conçue principalement pour les calculs rapides d’escaliers droits simples. Merci pour votre remarque, elle nous aidera à améliorer les prochaines versions.

### 1/5 — Can’t cancel

*2025-05-10*

There’s no way to cancel your subscription within the app. If there is it’s not obvious and the developer is not responsive to requests for help.

**Developer response:** Hi,
Thank you for your feedback.

Subscription management and cancellation are handled through the App Store account settings, and information about subscriptions is also included in the app description before purchase.

Thank you for your feedback — it helps improve the user experience in future updates.

### 1/5 — Cancelled after poor numbers that didn’t add up

*2025-04-18*

Cancelled after numbers made no sense

### 1/5 — I’m not a fan of the idea that you make your app look like a learning tool, actually it’s bloatware.

*2025-02-01*

I am very experienced in takeoffs and Iso’s from many different companies and -regions ,  so I would like to be clear about the best approach for this project, disclose your contractual terms prior to download. If the app doesn’t provide uninstall option then I can add one for you.

### 1/5 — Why pay money when you can get it for free?

*2025-01-23, version 2.0.0*

I downloaded the app with a free trial period and there appears to be no way to cancel it so that you will not be charged.

### 1/5 — Obnoxious ads

*2024-10-24*

The ads are obnoxious. And have nothing to do with construction.

### 1/5 — Fraud

*2024-08-03*

Attempted to discontinue trial but there is  no option to do so. Also tried to contact them to cancel and no response. They make you opt into a trial but dont give you option to cancel and just take your money.

**Developer response:** Hi,
Thank you for your feedback.

The app offers a free trial period for eligible users, and trial subscriptions can be cancelled anytime through the App Store account settings before the renewal date. Subscription details are also provided in the App Store description before purchase.

Thank you for sharing your experience. Your feedback helps improve future updates.

### 1/5 — Horrible

*2024-06-10, version 2.0.0*

OMG this is a horrible app. Give me a break.

### 1/5 — Scam

*2023-11-04*

Total scam does not provide any information  just transfer you to another app to buy.

### 1/5 — I'm a carpenter and I couldn't figure this stupid NFL

*2023-08-20*

I'm a carpenter and I could not figure this stupid app Al

### 5/5 — Southern Oregon Contractor Services

*2026-05-05*

I have been using this app for 7+ years now. It has been very useful!

### 5/5 — Really helpful

*2024-10-21*

Gave me the information that I needed. Slow down on the flipping of the device maybe…a close shot of
The end cuts. Just thoughts.. mine worked out.
Thank you.

### 5/5 — Doesn’t work for me

*2024-09-29*

Just didn’t work for me I’m canceling

### 5/5 — Clunky, more features needed

*2021-03-07*

Full pic incl floor level and landing level with joist height.  Stringers do not float in air.

### 5/5 — Stair Calc

*2021-02-26*

Very easy to use

### 5/5 — Easy to immediately understand and use

*2020-05-03*

If your need is to calculate your rise, run and stringer specs, this is perfect. Pros: 1) interface is visually clean 2) obvious how to input and calculate 3) output gives variety of options 4) quickly run various scenarios 5) No in app ads! 6) Free!  Cons: 1) Apparently the developer won’t actually come to the job site and cut the stringers for me.  😀
My project is to replace two precarious staircases in a home built in 1923. For a remodeling situation where we are dealing with several variables and wanting to try “what if’s?” this is perfect. Thank you Dang Phan!

**Developer response:** Your project is interesting!  I really appreciate your comments and suggestions.  Wish your work smoothly.

### 3/5 — Too limited

*2024-03-04*

I had to fit steps between a preexisting loft and a preexisting landing space and needed to know the rise and run by backing into those numbers. This app couldn’t help.

### 3/5 — Kinda helps

*2020-06-23*

Was looking for something that would calculate the total run based on height. Have to enter the total run which is what I needed to know. If you have run/rise then it gives options for number of stairs.
