Creat iPad App to collect Calibration Data

I would like an iPad Application that will collect our Instrument Calibration Data, then save the data to a CSV file that is then stored on the iPad until it has internet connectivity. When internet connectivity is available, the app should upload the files to a cloud storage service like Dropbox, Google Drive or AWS. The data to be collected: -Client Name -Site -Project -Area -Tag Number -Description -Calibrated By -Date -Input Units (Selectable from a list) -Output Units (Selectable from a list) -Span From -Span To -Output From -Output To -0%U As Found -25%U As Found -50%U As Found -75%U As Found -100%D As Found -75%D As Found -50%D As Found -25%D As Found -0%D As Found -0%U As Left -25%U As Left -50%U As Left -75%U As Left -100%D As Left -75%D As Left -50%D As Left -25%D As Left -0%D As Left When the Span & Output Data is entered, a Table should pre populate with Input values in the following fashon: %of Input Input Output As Found As Left 0%U a b 25%U c d 50%U e f 75%U g h 100%D i j 75%D g h 50%D e f 25%D c d 0%D a b a = "Span From" "Input Units" b = "Output From" "Output Units" c = ("Span To" - "Span From") * 0.25 "Input Units" d = ("Output To" - "Output From") * 0.25 "Output Units" e = ("Span To" - "Span From") * 0.50 "Input Units" f = ("Output To" - "Output From") * 0.5 "Output Units" g = ("Span To" - "Span From") * 0.75 "Input Units" h = ("Output To" - "Output From") * 0.75 "Output Units" i = "Span To" "Input Units" j = "Output To" "Output Units" The Input & Output Columns Are display only, non-editable. The As Found & As Left Columns are input columns. When user is finished they can press save and the iPad The user will be able to view a list of the stored calibrations, the list will be in a tree form with the following hierarchy -"Client Name" -"Site" -"Project" -"Area" The filename will be the date in the format YYYYMMDD followed by a hyphen then the "Tag Number". The file will indicate if it has been uploaded to the storage location by means of a symbol or color. The user will be able to select the record to view or edit it, they will be able to save it when complete. Where the "Client Name", "Site", "Project" & "Area" are already recorded, when completing the form the user can choose by drop down box the existing data or choose to add new data. "Site" data is individual to "Client Name" "Project" data is Individual to "Site" "Area" data is individual to "Project" CSV file is to be stored on the Cloud Storage in folders in the same Tree type hierarchy, as described above Company logo will be provided and needs to be on each page.
