Keep a clear record of your spa care without relying on memory. Spa Spartan Lite is an on-device maintenance log for portable spas and hot tubs. Record water tests, chemical additions, routine care, and important events, then review the history when something changes. KEEP A USEFUL HISTORY • Record sanitizer, pH, total alkalinity, and calcium hardness readings. • Log chemical additions, filter cleaning, cartridge changes, water changes, heavy use, and other maintenance. • Review recent activity and pH, alkalinity, and sanitizer trends. • Keep the chemistry context attached to earlier water tests when your setup changes. STAY AHEAD OF RECURRING CARE • Create reminders for filter care, water changes, cartridges, cover care, and other recurring tasks. • Optionally receive one local daily summary when enabled reminders are due or overdue. • Notifications are off by default and scheduled on your device. KEEP A BACKUP YOU CONTROL • Export a JSON backup and restore it later. • Restore checks preserve your current history as recovery data before replacement. • There is no account or built-in cloud sync. EXPORT FOR AI ANALYSIS Spa Spartan Lite can organize your saved spa profile, summary counts, recent reading trends, the latest five water tests, the latest five chemical additions, the latest five maintenance events, and active care reminders into a text summary. The summary is created on your device. Spa Spartan Lite does not contain or connect directly to an AI service, and nothing is sent automatically. You decide whether to copy or share the summary and choose the destination. Spa Spartan Lite is a recordkeeping and reminder tool, not chemical dosing advice. Follow product labels, spa and test-kit manufacturer instructions, and qualified pool or spa professional guidance. Do not mix chemicals unless product directions explicitly say it is safe.

Verdict
The clearest difference is price: ZEFNET Charge at Free against Spa Spartan Lite's $0.99. ZEFNET Charge also leads on ratings volume (26 vs 1) and iOS requirement (11.0 vs 15.0). Spa Spartan Lite's advantage is rating (5.0 vs 1.6). On ads, in-app purchases and device support there is nothing between them.
