Stop checking twice. Snap a photo, build a checklist, track anxiety - yepp remembers so you don't have to.
yepp - Your OCD Companion
Ever stood at your front door wondering, "Did I lock it?" Or walked back to check the stove... again? You're not alone. yepp was built for anyone who struggles with compulsive checking - giving you peace of mind with a simple, photo-based proof system.
How it works:
- Snap - Take a photo of what you checked (door, stove, wallet, anything)
- Checklist - Add items so nothing is missed
- Track Anxiety - Rate how you feel after each check (Calm to Panic)
- Voice Notes - Speak your thoughts instead of typing
- Auto-Delete - Controls expire after 1-90 days so your gallery never clutters
- Re-Check - Need to verify again? Add new photos without losing history
- Templates - Save routines ("Evening Lockdown") and reuse them instantly
