Product details
Built around one clear job.
Each product begins with a practical problem and removes everything that does not help solve it.
Explore a monthly fee using recorded costs and a target margin. Scenarios are estimates that depend on your inputs; they do not set customer prices or guarantee earnings.
The Free plan includes every current tool for one active service location. Two locations for the same client count as two sites. Paused and archived sites do not count toward the active-site limit.
Pro unlocks unlimited active sites with a one-time purchase and no monthly or annual subscription. Google Play shows the current local price and applicable taxes before purchase.
Enter records manually or import CSV, export readable CSV files, and create a password-protected business backup. Business records stay on your device unless you export them. Google Play handles Pro purchases and purchase checks; its billing SDK also handles technical diagnostics.
Built for one operator working on one device, initially for the US and Australia. PoolMargin does not provide cloud sync, invoicing, payment collection or automatic route optimization. The app interface is available in English and Spanish.

Before you download
A few useful things to know.
What can I do with the free version?
The free version includes every current tool for one active service location. Two locations belonging to one client count as two sites. Paused and archived sites do not count toward the active limit; the optional one-time Pro purchase removes that limit.
Can PoolMargin help me choose a monthly service price?
Enter your revenue, chemicals, labor, travel and overhead, then explore a monthly fee with a target margin. Results depend on your entries and include the cost of your own time. They are estimates, not guaranteed profit or automatically assigned customer prices.
Does it sync a team or issue invoices?
PoolMargin is for one operator using one device. It does not provide team cloud sync, invoicing, payment collection or automatic route optimization. You can import or export CSV and create a password-protected backup. The app interface is in English and Spanish.
