ReefKeep vs ReefCMD

ReefKeep is a modern, private tracker for saltwater and freshwater aquariums — built for hobbyists who want fast logging and proactive insights, not just prettier graphs. WHAT YOU CAN DO • Log 8 parameters in under a minute with a clean one-screen entry • Scan Hanna Checker readings with the camera — no more transcribing numbers • Track alkalinity, calcium, magnesium, nitrate, phosphate, pH, salinity, temperature and any custom parameter you care about • See trends as native charts with your target ranges overlaid • Schedule recurring tasks (water changes, filter swaps, skimmer cleaning) with local reminders • Record livestock with timelines for spawning, fragging, moves and notes THE INSIGHTS ENGINE Other apps show you numbers. ReefKeep tells you what they mean. • Trend alerts — "Alkalinity has fallen 8% over your last 5 tests" • Correlation hints — "Alk and calcium are both dropping. Check your 2-part dosing." • Stale data warnings — "You haven't tested nitrate in 12 days" • Smart water-change recommendations based on your actual nitrate trajectory, not a fixed schedule Everything runs on your device. Nothing leaves your phone unless iCloud sync is enabled. ASK THE ON-DEVICE COACH With Apple Intelligence (iPhone 15 Pro and later), tap any insight and get a plain-language explanation grounded in your own tank's readings — all processed on-device, no accounts, no servers. BUILT FOR REEFERS • Dark mode first — matches how you actually use the app next to a lit tank • Dual units everywhere: L/gal, °C/°F, ppt/SG, dKH/meq/ppm • Multiple tanks (Pro) • iCloud sync across your iPhone and iPad — included, not an upgrade • Zero ads, zero tracking SDKs, zero account required PRO UNLOCKS • Unlimited tanks • Unlimited parameter history • Insights engine • CSV export for your records • Photo galleries • Apple Watch (coming soon) Monthly and yearly subscriptions, or a one-time lifetime unlock if you prefer to own your tools. ReefKeep is built by a small team that uses it on their own tanks. We're not trying to be everything for every hobby. We're trying to be the tool you open once a week without thinking, and the app that catches a problem before it costs you a fish. The app applies the standard Apple Terms of Use (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
