AIS targets are plotted relative to iPhone/iPod/iPad position. Tapping on an AIS target displays details (i.e. speed, course, destination, type, length, etc.). GPS and Wind data can also be viewed on the Instrument panel. You can also display the AIS targets over your Navionics charts. With a one off In App purchase, iAIS can use all your existing Navionics charts with no additional charges for the charts. You can share your boat's live position, speed and course and be visible on other free internet based AIS apps and web sites like BoatWatch and MarineTraffic if you have a valid MMSI number for your boat. In the US you can obtain an MMSI number for your boat by visiting http://www.boatus.com/mmsi. In the UK visit https://www.ofcom.org.uk/manage-your-licence or email us for an internet only MMSI number. Please note that continued use of GPS running in the background can dramatically decrease battery life. NOT FOR NAVIGATION iAIS should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction. ## Key features - AIS target plotting - NMEA data instruments - AIS target details display - Navionics chart overlay - Live boat position sharing - GPS and Wind data view ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Navionics Charts Upgrade | $9.99 | one-time | ## Recent user reviews (10 of 23) All indexed reviews: https://appshunter.io/ios/app/iais/id394667307/reviews.md ### 1/5 — Unbrauchbar *2023-08-18, version 3.4* App stürzt sofort ab sobald mit ais Transponder verbunden. Also komplett nutzlos ### 1/5 — Misleading utube video *2023-03-10, version 3.4* No mention, I would need to buy a transponder for over a £1000. Feel ripped off ### 1/5 — Used to work, now, not so much *2023-02-01* Up until recently this simple little app was reliable, fast and accurate. Now it freezes, locks up, slows down or crashes. Even after downloading a fresh copy, same behaviour. When contacting digital yachts you’re sent on a useless goose chase for boiler plate solutions. Digital Yacht’s hardware and hardware customer service is top notch but the software app end of things needs lots of work. Currently useless. ### 1/5 — Inutile *2022-06-09, version 3.4* Cette appli ne montre pas les cibles sur l’écran. Je n’en vois donc pas l’intérêt. ### 4/5 — Works very well with my AMEC Camino W Wifi *2021-08-30, version 3.3* Just missing a collision course alarm. ### 1/5 — No targets show *2021-07-19, version 3.3* Despite known targets in the area, non show on this app. Tried to go to app support, dead end there, bad page. So… worthless. ### 1/5 — nulle et tromperie *2020-02-14, version 3.3* cette appli vous renvoie sur une autre payante .... procédé malhonnête.... mauvais point pour digital yacht vaudrait mieux arrêter de genre de bidouille pas digne de pro.. ### 1/5 — Cannot connect *2019-10-17, version 3.3* Just paid £9.99 for this and I am unable to connect, so not only am I unable to use it on my Navionics but also as a stand alone app! ### 4/5 — Alarm cpa *2019-07-09, version 3.3* Il download delle carte navionics funziona bene e anche la connessione con il transponder Nomad. Sarebbe utile la presenza di un allarme sonoro e visivo per cpa e tcpa. Sarebbe utile anche inserire il pinch per lo zoom e non solo con + o -. ### 1/5 — tromperie sur les fonctions annoncées *2018-08-24, version 3.2* pas grand intérêt, vous obligé à payer une option chez navionics pour voir les cartes. malgré la wifi, les cibles AIS n’apparaissent pas alors que c’est le seul intérêt de cette appli !!! seulement les indications de vitesse et de position donc aucun intérêt. ## Frequently asked questions about iAIS ### What is iAIS? iAIS is a tool for plotting AIS targets and viewing NMEA data, designed to work with the DigitalYacht iAIS WiFi receiver.
