Sitting all day is wrecking your neck. Stiff nudges you during work hours, walks you through a two-minute desk stretch, and judges you until it sticks.
Your body was not designed for eight hours in a chair. Stiff helps you survive it anyway.
Stiff is a desk stretch reminder that nudges you during your actual working hours - never at 11pm - and walks you through a fix for whatever is aching. Neck, shoulders, lower back, wrists, hips, eyes. Under two minutes. No equipment, no gym, no getting changed.
And Stiff, the sloth who lives in the app, will judge you the whole time. Gently. At first.
WHY IT ACTUALLY STICKS
Most stretch apps are a list of exercises you open once and never again. Stiff is a habit. Reminders arrive on your schedule, sessions are short enough that you have no excuse, and every stretch you finish earns XP, feeds your streak, and slowly turns Stiff from openly disappointed into something close to proud.
BUILT AROUND YOUR WORKDAY
• Set your work days and hours - reminders only fire when you're at your desk
• Choose your rhythm: every 30, 45, 60, 90 or 120 minutes
• Choose your session: one quick reset, a balanced pair, or a three-stretch flow
• Tell Stiff what hurts and your sessions lean toward that area
• Like and dislike stretches to shape what you get
41 DESK-FRIENDLY STRETCHES
Everything is done sitting at your desk or standing next to it, with a guided timer, plain instructions and optional sound cues. Targeted sets for neck and shoulders, lower back, wrists and hands, hips and posture - plus eye-strain breaks for screen fatigue.
