About

Shift

Features
Read full description

Start your HIIT workout in 3 taps. No setup friction. No clutter. Just a clean, fast interval timer built for people who actually train. Shift is a purpose-built HIIT timer designed for speed. Set your work intervals, rest periods, and rounds — then go. No account required. No ads. No bloated feature set. WHAT SHIFT DOES: — Custom interval configuration: work time, rest time, rounds, sets — Tabata, EMOM, and custom HIIT protocols — Clear audio cues and haptic feedback so you never miss a transition — Visual countdown optimized for glanceability mid-workout — Minimal UI that stays out of your way BUILT FOR: — Home workouts with no equipment — Gym training between sets — CrossFit-style timed circuits — Tabata protocols — Any interval-based training WHY SHIFT: Most timer apps are either too simple (just a stopwatch) or too complex (10 screens before you start). Shift sits in the sweet spot — fully configurable but fast to start. Designed by Credes, a product studio that ships tools people actually use. Start training. Not configuring.

MaskID helps you prepare identity documents, forms, and PDFs before sharing. Import or scan a document, cover only the information you choose, review every page, and export a protected copy. PREPARE A DOCUMENT • Scan with the built-in document camera or import an image or PDF from Photos and Files. • On-device text recognition can suggest details to review. You decide which areas to cover. • Work with multi-page documents and review each page before export. CHECK THE COPY • Choose a redaction style and adjust each mask yourself. • Export a protected PDF or image and review the result before sharing. • MaskID can check an export for hidden text and common metadata. These checks cannot confirm that you selected every sensitive area; inspect the complete document and the recipient. STORE DOCUMENTS ON YOUR TERMS • The local library is protected with device-only encryption. The optional Vault adds Face ID or PIN protection and keeps Vault documents on this device. • Core document protection works without a MaskID account. Optional iCloud sync uses your private CloudKit database. Optional Google Drive and Dropbox imports let you choose a file from those services.
