Does your pet weigh what they should? PetScale is the smart, science-backed weight tracker built for pet owners who want more than a number on a scale. By combining your pet's species, breed, gender, and age, PetScale calculates a personalized healthy weight range and gives you the tools and guidance to help your pet reach — and stay at — their ideal weight.

PetScale knows that, and your recommendations reflect it. ~Breed & Profile-Specific Weight Tracking Add your pet's profile once and let PetScale do the rest. We factor in species, breed, gender, and age to determine what a healthy weight actually looks like for your pet — not an average animal. ~Weight History & Progress Charts Log weights over time and watch your pet's journey unfold. Easy-to-read charts show trends at a glance so you can celebrate progress and catch concerns early. ~Personalized Goal Recommendations Whether your pet needs to lose, gain, or maintain their weight, PetScale provides tailored tips on feeding portions, activity level, and lifestyle adjustments — updated as your pet ages and changes. ~Appointment Reminders Set reminders for vet visits, annual checkups, grooming appointments, dental cleanings, and more. PetScale keeps your pet's care calendar organized so nothing slips through the cracks. ~Supports a Wide Range of Pets & Breeds Dogs, cats, and more — PetScale is built to support hundreds of breeds across multiple species, so every pet in your home gets personalized attention. ~Clean, Simple Dashboard See your pet's current weight, goal weight, progress, and upcoming appointments all from one clean home screen.

Close your eyes. You can still follow every breath. BreathZen is a breathing rhythm app designed for quiet practice. Gentle human breath guidance makes inhale and exhale distinct by ear, while holds remain silent. There are no spoken commands and no need to keep watching the screen. FIVE BUILT-IN PATTERNS — FREE • 4-7-8 Breath: a longer exhale for winding down • Box Breathing: four equal phases for a steady rhythm • Coherent Breathing: smooth 5.5-second inhales and exhales • 4-6 Calm Breath: gentle pacing without holds • Morning Wake Breath: an inhale-led rhythm for starting the day MADE FOR CLOSED EYES AND LOCKED SCREENS With sound enabled, your practice continues when the screen locks or you switch apps. The Lock Screen and Control Center show the current phase, pattern, overall progress, and playback state, with pause and resume controls close at hand. A RHYTHM THAT FITS YOU Set inhale, hold, exhale, and rest in half-second steps, up to 60 seconds per phase. Preview the animation and sound while you edit, with live cycle length, breaths per minute, and session duration. Editing and auditioning are free. Saving custom patterns is a one-time purchase, never a subscription. COUNT BREATHS OR SET A TIME Practice by rounds or choose 1–120 minutes. When time is up, BreathZen finishes the last complete breath instead of cutting you off halfway through a phase. Paused time does not count against the session. PRIVATE BY DESIGN No account, ads, tracking, or analytics SDK. Everyday practice works offline. Optionally save completed sessions to Apple Health as mindful minutes. All five built-in patterns and the complete core practice experience remain free. Custom pattern saving is a one-time unlock. Practice only within a comfortable range. Stop and return to natural breathing if you feel dizzy, strained, or unwell. BreathZen supports general wellness and mindfulness; it does not provide medical diagnosis or treatment.
