SaltCheck — Softener Salt

No smart sensor needed. SaltCheck estimates your salt level from a couple of details.

Hard water is back the moment your brine tank runs dry. SaltCheck estimates your salt level — no sensor hardware, works with any softener — and reminds you before it runs out. • Live tank level based on your softener size and household • One-tap refill log ("save & reset to full") with bag count • Refill forecast so you can buy salt before you need it • Low-salt alerts at your preferred time SaltCheck Plus ($7.99/yr, 7-day free trial): multiple softeners (home + cabin), consumption history graph, home screen level widget. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; manage or cancel it anytime in your App Store account settings.
