A digital logbook that fills itself. Manta notices when you cast off, tack, gybe, drop anchor or moor, and writes it into your log by itself. Every automatic entry stays editable.
Automatic log entries
You sail, Manta writes. It notices when you cast off, tack, gybe, drop anchor or moor, and puts each moment into the log with its time. At the end of the day the log is already there.
What Manta recognises
- Departure and arrival
- Engine on and off, from your instruments or the hull's vibration
- Anchoring, told apart from mooring in a harbour
- Tacks, gybes and sail changes, on sailboats with the engine off (Manta Pro)
Manta detects all of it on every trip. The Pro entries show as soon as you have Pro, on your earlier trips too.
How it works
Manta combines your iPhone's GPS with its motion sensors. If your plotter or a WiFi gateway is connected, it adds the instruments' data as well. No wiring and no extra box on board.
Telling entries apart and correcting them
Automatic entries carry a small sparkle, so you always see what Manta wrote and what you wrote. Tap one to change its type or time; it then counts as your own entry. Manual entries sit in the same log, in time order.
Turning on automatic logging
Start a recording, and automatic logging runs with it. Under Settings → Automatic logging you choose which kinds of detection are on.
Questions
What does Manta log on its own?
Departure and arrival, engine on and off, and anchoring, told apart from mooring in a harbour. With Manta Pro it also logs tacks, gybes and sail changes.
Do I need extra hardware?
No. Manta uses your iPhone's GPS and motion sensors. If you connect your instruments, it uses their data too.
What if an automatic entry is wrong?
Tap it to change its type or time. From then on it counts as your own entry.
Can I switch some detections off?
Yes. Under Settings → Automatic logging you can switch each kind of detection on or off.
