Con l'app '4 Wind' puoi avere tutti i link utili degli spot più ventosi, per consultare i servizi più utili di webcam e previsione meteo, da web o app, e sostituire introvabili link del browser tramite una comoda mappa. PERCHE' L'app si chiama '4 Wind' , nome che richiama anche una celebre rivista sportiva che oggi è disponibile in versione digitale. Per gli appassionati di sport acquatici che richiedono la presenza del vento, come ad esempio windsurf, wingfoil e kitesurf, i luoghi in cui si trova il vento adatto a questi sport vengono chiamati "spot". Per ogni spot, si cercano di intuire le condizioni del vento utilizzando il web e le app più diffuse, guardando webcam live, previsioni del vento, condizioni meteo attuali Le informazioni sono spesso distribuite su tantii link del browser e anche diverse app esistenti, e si eseguono sempre le stesse ricerche di queste informazioni (webcam, previsioni e meteo). L'app '4 Wind' fornisce una soluzione rapida e intuitiva per accedere ai servizi già disponibili tramite web o app, tramite una mappa con le icone che rappresentano ogni servizio utile, posizionate vicino alle coordinate dello spot IMPOSTAZIONI Le preferenze dell'utente vengono salvate in locale sul dispositivo; è possibile cambiarle dalla schermata di configurazione (attivazione servizi e apertura della mappa nella posizione attuale o spot preferito/selezionato). Lo spot preferito si imposta con la stellina, dal popup dello spot o dalle liste. SERVIZI I servizi che l'app rende piu' accessibili sono già ampiamente utilizzati dagli sportivi che praticano windsurf/wingfoil/kitesurf, ma potrebbero non essere conosciuti per chi inizia o per chi non frequenta un particolare spot La lista dei servizi che si possono consultare tramite icona/link si trova nel tab Setup. Se l'utente vuole puo' escludere la ricerca di alcuni servizi: - Centrometeolombardo - Lamma - Meteoam - Meteoblue - Meteoswiss - Notiwind - Panoramicams - Vedetta - Vision_environnement - Weathercam - Whatsupcams - Windfinder - Windguru - Windyapp - Windycom L'app fornisce informazioni da consultare in tempo reale, quindi la lista completa di spot con link e servizi, viene letta da un web privato quando l'app viene aperta. L' elenco di spot e' suddiviso in 4 tipologie di informazioni : webcam / previsioni / altro / app , di cui solo l'ultimo e' ad uso interno Ogni elemento ha un titolo, una location (nome, coordinate gps, indirizzo completo) la tipologia e il servizio in uso (a cui spesso corrisponde una app su App Store) Tutte queste informazioni vengono visualizzate in dettaglio nelle liste o dalla mappa nel popup apparso selezionando un servizio di uno spot, da cui posso aprire il link proposto per quel servizio, oppure aprire l'app corrispondente, se appare la sua icona, o interagire in altri modi, copiando e/o condividendo alcune informazioni (tramite tocco prolungato) Se non esiste un servizio per quell'elemento oppure il link e' generico ma utile per questi sport, nei dati condivisi verra' associato con il tipo 'other', e sarà disponibile dal tab Lista, tramite l'elenco 'Other'. Solo gli spot con una location gps (anche approssimativa) sono accessibili dalla mappa in app, tramite una icona che corrisponde al servizio (vedi icone in Setup), circondata da un anello colorato che corrisponde alla tipologia (blu per le 'webcam', verde per i 'forecast', nero per 'other') L'app 4 Wind contiene già decine di link di spot ventosi, soprattutto Italiani (Sardegna, Liguria, Lago di Como e del Garda), ma anche Francesi e della Grecia. Ogni utente puo' suggerire di aggiungere alla lista condivisa, dei nuovi link e servizi per gli spot frequentati, fornendo se possibile le coordinate, tramite la mail dello sviluppatore, disponibile nel tab Setup. Lo sviluppatore valuterà le informazioni fornite, lo spot e i relativi link e servizi, prima di aggiungerli alla lista letta da '4Wind', e saranno automaticamente disponibili, per tutti gli appassionati !!

Verdict
The clearest difference is in-app purchases: 4 Wind at none against PredictWind's 10. PredictWind's advantage is chart position (#20 vs unranked) and iOS requirement (16.0 vs 26.6). On price, update cadence, ads and device support there is nothing between them.
