MyDiveLog è il logbook per chi si immerge con più di un computer, o li ha cambiati negli anni. QUANDO DUE COMPUTER HANNO REGISTRATO LA STESSA IMMERSIONE, NE FA UNA RIGA SOLA Non due voci doppie da sistemare a mano: una sola immersione, che tiene il meglio di ciascuna fonte. Il profilo con più informazioni, la temperatura di chi ce l'ha, i gas di chi li ha registrati. Il riconoscimento non si fida solo dell'orario — confronta la forma del profilo — perché gli orologi dei computer subacquei vanno ognuno per conto suo. IMPORTA QUELLO CHE HAI GIÀ UDDF, Shearwater (XML e archivio Cloud), Garmin FIT, LogTRAK, Subsurface, CSV. I formati si riconoscono dal contenuto, non dall'estensione: trascini i file e basta. Le immersioni senza file — computer a noleggio, batteria scarica, libretto di carta — si aggiungono a mano. SCARICA VIA BLUETOOTH Dal computer subacqueo al telefono, senza passare da un cavo o da un programma sul computer. Con segnalibro: dal secondo collegamento in poi prende solo le immersioni nuove. LEGGE DAVVERO I PROFILI Bühlmann ZH-L16C con gradient factor, esposizione all'ossigeno secondo le tabelle NOAA, curva e obbligo minuto per minuto, i sedici compartimenti disegnati. Ogni misura dichiara su quante immersioni si basa: niente numeri stimati spacciati per misurati. STATISTICHE CHE DICONO QUALCOSA Consumo, assetto, ripetibilità, muta per temperatura, zavorra per tipo d'acqua. E suggerimenti di miglioramento con sotto le prove numeriche, così puoi non essere d'accordo. PIANIFICA PRIMA DI ENTRARE Gas e decompressione: piano delle pressioni, riserva, fasi d'emergenza, multi-livello, cambi alla MOD, Bühlmann-GF e VPM-B, CCR. Anche in ricreativo le soste si calcolano quando il piano esce dalla curva. L'ARCHIVIO È TUO Sta sul dispositivo. Niente pubblicità, niente statistiche d'uso, niente abbonamento. L'accesso con Apple o Google serve solo se vuoi allineare più dispositivi, ed è facoltativo: senza, l'app funziona identica. Esci quando vuoi in UDDF, CSV o KML. Codice sorgente pubblico, licenza MIT. ATTENZIONE MyDiveLog è uno strumento di registro, analisi e pianificazione. Non è un computer subacqueo, non sostituisce il tuo, e non va usato in acqua per prendere decisioni. Le immersioni si pianificano con la propria formazione e i propri limiti.
