SubItUp's mobile time clock solution, is a robust time and attendance solution that can be easily configured to meet the needs of your business or organization. With an intuitive workflow, GPS capture and device tracking, online and offline modes, real-time reporting, and multiple authentication types - the SubItUp Time Clock app will fit your unique needs. GPS location and real-time tracking: Every punch is associated with a GPS location. Managers can see in real-time the location of employee clocking transactions, run reports to view saved geotag location data and other statistics, and perform other operations through the SubItUp management portal. Multiple authentication methods: Employees can be authenticated using various entry methods including having the device's camera function as a barcode scanner (saving you money by eliminating the need to purchase or lease additional equipment). Other entry options include using an external scanner, unique pin number entry, phone number, username and password, and more. Online and Offline Modes: Don't always have a connection? Use the SubItUp Time Clock time clock in areas with high cell-service saturation and/or no internet access. Our offline time clock syncs time clock data directly with the SubItUp platform once a connection is established Intuitive Workflow: We know your team doesn't have time to troubleshoot issues in the field. That is why the SubItUp Time Clock user experience was built so managers and employees can be trained in under 5 minutes. If you do need assistance, SubItUp's support team is here to help with call, chat, and email support. Roster Punch: Need to quickly clock in a group of employees? SubItUp Time Clock's roster time clock feature allows managers to manually clock in multiple staff at the same time. Set clock in times based on employees’ scheduled shift start time or by the time the manual clock in occurred. Schedule Verification: Want to more accurately project labor costs and save your managers time doing time and attendance reconciliation? By having employees clock in for scheduled time, the SubItUp Time Clock app will reference an employee's scheduled shift and automatically reconcile their clocking transactions with their scheduled shift. Restrictions and thresholds can be set to only allow clock in times based on the start and end times of the scheduled shift, prompt notifications to managers for certain clocking transactions, and require manager overrides for certain actions. Need to have employees clock in for unscheduled time? Don't worry, the SubItUp Time Clock app can be configured to allow for unscheduled clocking transactions as well. SubItUp Time Clock is the mobile time clock solution for SubItUp's scheduling platform. SubItUp was founded at MIT in 2007 and, as of 2017, has over 35 million shifts under management.

Nullgen AI Blocker is a parental-control and content-blocking app for families, schools, and workplaces. It stops AI chatbots and AI websites from working on this iPhone or iPad — in Safari, Chrome, and the apps themselves. Set it up once and it stays on. PART OF THE NULLGEN AI BLOCKER SUITE • Browser extension for Chrome, Edge, Firefox, and Safari — detects AI prompt boxes on any website and stops typing and pasting into them, on the device. • iPhone and iPad app (this app) — blocks known AI apps and websites across most websites and apps on the device. • Mac app — the same protection for Safari on the Mac. One Nullgen Pro account covers every device, with the same rules and the same approvals everywhere. WHAT IT BLOCKS ChatGPT, Gemini, Claude, Copilot, Grok, Perplexity, DeepSeek, Character.AI, Poe, Midjourney, and more than 70 other AI services. The list is kept up to date by Nullgen so new tools are covered without an app update. HOW IT WORKS To work, the app asks iOS for permission to add a VPN configuration. That configuration is used only to filter AI destinations on this device. It is not a traditional VPN: your traffic is never routed through Nullgen or anyone else, and nothing you browse is sent to our servers. When an app or browser tries to reach a known AI destination, the request is answered on the device and simply does not load. Everything else works normally. NO OFF SWITCH There is no button in the app to pause or disable blocking. That is the point: the person holding the phone is often not the person who installed it. FREE FOR 3 DAYS Start the trial with no account and no card. It lives on this device. When it ends, protection continues with Nullgen Pro. NULLGEN PRO — FAMILY Subscribe in the app, then link this iPhone or iPad to your Nullgen account at nullgen.ai/link. From there a parent can: • Approve or deny access requests. A child taps “Request AI access”, picks the tool and how long they need it, and the parent approves from the Nullgen dashboard. The tool unblocks instantly for exactly that time — fifteen minutes, an hour, a day, or permanently. • Set allow and deny rules per AI tool for each child. • Cover every device in the household: browser extensions for Chrome, Edge, Firefox, and Safari, plus the iPhone, iPad, and Mac apps, under one subscription. NULLGEN PRO — EDUCATORS AND ENTERPRISE Schools and companies deploy Nullgen across managed devices and route AI access requests to named approvers. Learn more and sign up at nullgen.ai. PRIVACY • Blocking decisions are made on the device. • Nullgen never receives which sites you visit or what you type. • The free trial creates no account. • Access requests contain only the tool, the duration, and an optional note you write. • Nullgen does not sell, share, or disclose any data from this app to third parties, and does not use it for advertising. Privacy Policy: https://nullgen.ai/privacy WHAT IT DOES NOT DO AI features built into services that share ordinary hosts — such as AI answers inside a search engine or a social app — are not blocked separately, because blocking them would block the whole service. On a personal, unsupervised iPhone, iOS still allows the VPN configuration to be removed in Settings; that is an operating-system limit. SUBSCRIPTION TERMS Nullgen Pro Family is offered as a monthly or yearly auto-renewing subscription, billed through your Apple account. Payment is charged at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel in Settings › Apple Account › Subscriptions.
