PoolStop is an offline pool chemistry and visit log for technicians. You are responsible for how you use readings, doses and shared notes. Display target ranges are guides only and are not chemical, medical or safety advice. Always follow product labels and applicable law.
PoolStop Pro is an auto-renewing subscription offered through Apple In-App Purchase: $14.99 per month or $89.99 per year (with a 7-day free trial on the annual plan where eligible). Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Any unused portion of a free trial is forfeited when you purchase a subscription where applicable.
We grant you a personal, non-transferable license to use PoolStop on Apple devices you own or control, subject to the App Store terms. You may not reverse engineer, resell or misuse the app.
Data you enter is stored on your device. Backups and shares you initiate are your responsibility. See our Privacy Policy.
The app is provided “as is.” We are not liable for business losses, chemical decisions, equipment damage or any damages arising from use of the log. Some jurisdictions do not allow certain exclusions; those limits apply only to the extent permitted.
