ISN NFS
Read full descriptionHide full description
The BeringWatch Sentinel Harvest app is for trained community-based observers and local and traditional knowledge holders to record data during subsistence harvest activities conducted in their local communities. The BeringWatch Sentinel Community-Based Monitoring Network which includes the Harvest app was designed and refined over the past 15 years in Alaskan Native communities. Users of the BeringWatch Sentinel apps are located primarily in remote communities that are affected by a rapidly changing environment. The strength of the BeringWatch environmental data collection framework is that it is tribally-driven. Communities are better able to actively participate and lead data collection that both addresses community concerns and contributes meaningful scientific data to researchers, resource managers, and decision makers. BeringWatch Community-Based Sentinel Monitoring Programs are established using observation protocols and standardized methodologies for community-based recording of observations of wildlife, subsistence species and environmental phenomena at locations surrounding participating communities. These data, if collected in a repeatable and consistent manner over a long period of time, can provide valuable ecological reference points for the region. For information on joining the BeringWatch Sentinel Network please contact the Aleut Community of St. Paul Tribal Government.

FileNook is a private local file workspace for iPhone and iPad. Organize files, read documents and prepare materials without a cloud-drive account. Files and document processing stay on your device unless you choose to share them. FILE WORKSPACE • Create folders; browse, rename, move, duplicate, sort and search files. • Use favorites, recent files and a recoverable trash. • Import from Files, Photos, AirDrop and the share sheet. • Transfer files from a computer over local Wi-Fi—no account or upload to a cloud service. • Search supported document content and inspect detailed file information. SCAN & RECOGNIZE • Scan ID cards with optional purpose watermarks and image enhancement. • Extract editable text from photos and PDFs. • Extract tables with cell review and export to Excel. • Recognize QR codes without automatically opening links. • Transcribe local audio with selectable ranges and TXT or SRT export. PDF TOOLS • Create searchable or standard PDFs from photos and document scans. • Merge PDFs; organize, reorder, rotate, insert, remove and extract pages. • Split PDFs by page, fixed groups or custom groups. • Crop page margins, compress PDFs and password-protect PDF copies. • Convert PDFs to images or editable Word documents. • Export TXT and Markdown to PDF; add optional covers, contents and page numbers. • Combine photos, scans and selected PDF pages; set a consistent A4 or Letter page size. PHOTO & PRIVACY TOOLS • Convert image formats, crop or resize to exact dimensions, and save reusable material presets. • Compress photos, combine images and stitch long screenshots. • Add text watermarks to images or PDFs. • Permanently redact selected areas of images and PDFs before sharing. VIDEO & AUDIO TOOLS • Compress compatible videos and preview the result before saving. • Extract an audio track or selected time range from a video. READ & PLAY • Read PDF, EPUB, DRM-free MOBI, TXT and Markdown files. • Play local video and audio, including supported HDR video, subtitles, picture in picture and seek-preview thumbnails. LOCAL PROTECTION • Protect app access with an independent passcode and optional biometrics. • Create password-encrypted backups and password-protected ZIP archives. • App Lock protects access to the app; it cannot protect copies after you export or share them. Basic file operations, reading, audio and videos up to 30 minutes are free. Selected recognition, conversion and batch tools share 3 trial uses in total, with no daily refill. Each optional tool reward ad adds 2 uses, up to 2 ads per day. Videos longer than 30 minutes: unlock 3 different videos free each day, then watch an optional reward ad for 1 additional unlock. Reopening the same unchanged video that day does not use another unlock. Tool and video rewards are separate and unspent rewards do not expire. Pro is a one-time purchase that removes all ads and tool/video usage limits. File-size, page-count and batch safety limits still apply. No new monthly or annual subscription is offered.

Verdict
The clearest difference is in-app purchases: ISN NFS at none against FileNook's 3. ISN NFS also leads on ads (none vs shown) and iOS requirement (15.6 vs 26.0). FileNook's advantage is update cadence (every 6 days vs every 14 months). On price and device support there is nothing between them.
