About this app
La Cisternetta turns any group liquid goal into a live, physics-driven shared experience — whether your team is tracking hydration, running a coffee challenge, or chasing any liquid milestone together. TEAM CHALLENGES — NEW Create group challenges for any liquid: water, coffee, juice, or tea. Set a goal in litres, invite your crew, and watch a shared tank fill up in real time. Every log from every member counts toward the group total. Live leaderboards show who's leading the charge. PHYSICS TANK The signature feature: a 1,000L shared cistern rendered with layered animated liquid waves, accelerometer-driven physics, and real-time filling. Tilt your phone and the liquid sloshes. Move it and waves appear. It's not a progress bar — it's your group's live tank. GROUPS & EVENTS Create private or public groups. Start timed events with deadlines and countdown timers. Each event has its own scoped stats, leaderboard, and activity feed. Admins can manage members, approve join requests, and moderate events. LEADERBOARDS Filter by daily, weekly, or all-time. Rank by quantity or drink-type. See per-member breakdowns with live updates. LOCATION DIARY Every log carries an optional reverse-geocoded location tag — your activity feed becomes a map of where your group has been. REAL-TIME FEED A live activity feed with cheers reactions, location tags, and relative timestamps. Offline-resilient: logs are queued locally and synced when connectivity returns.
