Frequently Asked Questions
How do I create an estimate?
Start a new project, upload your PDF drawings (or take a photo of them), and add any notes about the scope of works. QSApp reads the drawings, extracts the scope, and lets you confirm the items before it prices the job.
How is my estimate priced?
Pricing uses a built-in rate book and your own profit and material margins, which you set in your Business Profile. You stay in control — you can review and edit every item before finalising.
Why should I check the dimensions?
QSApp reads the floor area and perimeter from your drawings, and those figures drive the quantities for foundations, walls, roof and finishes. Before generating an estimate, check the highlighted dimensions panel and correct anything that doesn't match the drawing — it takes seconds and keeps the whole estimate accurate.
Can I change a price I disagree with?
Yes. Open View / Edit Cost Breakdown on any project, change the quantity or the price on any line, and tap Save Changes. If you'd rather go back to the standard rates, tap Reset Prices from Rate Book.
How do I delete my account?
In the app, go to Menu → Business Profile, scroll to the Danger Zone at the bottom, and tap Delete Account. After you confirm, your account and all associated data (projects, business profile, and settings) are permanently deleted. This cannot be undone. You can also email us to request deletion.
I forgot my password.
Use the “Forgot password” option on the sign-in screen, or email us at jackletch.dev@gmail.com and we'll help you reset it.
How do I manage or cancel my subscription?
Subscriptions are billed through your Apple ID. To view, change or cancel, open the Settings app on your iPhone, tap your name, then Subscriptions. Cancelling stops the next renewal; you keep access until the end of the period you've paid for.
Do my credits expire?
No. Credits from a credit pack stay on your account until you use them.
