Most fishing apps show you where other people caught fish. Tenviro teaches you to look at
a piece of water you have never seen before and know 💡 where the fish is. Every drill is a
plan 🗺️ view of one real water type ⌨️ — a riffle-run-pool, an outside bend, a converging seam, a
weir sill, a drop-off shelf, a tidal gutter — drawn as honest geometry: depth in banded
colour, current as arrows whose length is the actual speed ⚡, cover and structure as plain
shapes.

You answer with three placements instead of four buttons. Drag ✋ the marker onto where the
fish is holding. Draw the cast entry and the drift so it presents through that zone without
dragging. Then put yourself on a bank — stand on the wrong ❌ side and the reveal shows the
fish bolting before your line lands. Each part is scored separately, and the reveal names
the mechanism that made the spot hold fish: velocity shelter, the food 🍎 conveyor above it,
oxygen, overhead cover, a thermal refuge, a structure edge. The Flow Flip bench re-renders
the same water at low, normal and high level 🧗 and the holding zone physically moves, so you
learn 📖 that the answer is conditional rather than memorised.

Around the drills sit the reference and field tools 🛠️: thirty hydraulic features, each with
the give-away signs visible on the surface and the mistake people usually make; a velocity
ladder that shows which of twenty-four species can hold, feed or gets flushed at a given
speed ⚡ and water temperature; a stopwatch tool 🛠️ that turns a floating twig and a measured
bank into a real current reading; spaced review of the features you keep misreading; a beat
planner 🗺️ that orders a stretch by light and time ⏱️ of day; and a river log 📝 where you record
what you actually found against what you predicted — with an optional photo 📸 of the water you
can tap 👆 to mark where the fish were.

Everything works offline 📴 and stays on your device 📱. It is a teaching tool 🛠️ built on general
hydraulics and fish behaviour, not a forecast of any particular river, and not a safety
guide.
