Starting is the hard part. Sidle starts with you. Sidle is an instant body-doubling companion for tasks that feel difficult to begin. No booking, camera or waiting room. Open the app when the moment to start appears, name the task, and Sid is already beside you. Type the thing you have been circling. Sid acknowledges it, asks for one physical first move, and then goes quiet while you work. You get a calm presence, a timer on your Lock Screen, and a session that still counts if you step away. FREE - Unlimited silent body-doubling sessions - Gentle, Steady, Quiet and Wry companion styles - Weekly on-device language variations - On-device Moments that keep your completed sessions together - No account or sign-up SIDLE PRO - A user-written βFor next timeβ move, kept only on this phone and ready at the next start - An on-device mid-session hello with optional voice, plus an optional background notification - For adults who separately consent: a short optional AI co-start that asks you to name one physical first move - One visible, clearable note from the latest eligible AI session, kept with this device's anonymous profile BUILT WITHOUT SHAME MECHANICS - No daily chain to protect - No red badge or guilt copy - No mid-session upsell - No camera and no person waiting for you Step away and the elapsed time still counts. Return after a gap and Sid simply meets you where you are. The free loop works without an account. Sidle's provider-backed Pro AI is for adults 18 or older. Pro session text is sent only after adult confirmation and a clear AI-consent step so Sid can generate the co-start and, after an eligible session, replace the brief note kept for the next Pro start. Profiles and notes are device-scoped; Sidle does not provide cross-device memory sync. Sid is an AI companion, not a person or professional service, and Sidle is not a medical or therapeutic product. The App Store shows the price, billing period and any introductory offer available for your storefront and Apple Account before you confirm a purchase. Introductory offers appear only when Apple reports that you are eligible. Subscriptions auto-renew until cancelled in Apple Account settings. A one-time lifetime option may also be available. Optional provider-backed AI has fair-use limits; the paywall keeps those details in a separate disclosure and explains that on-device Pro continues if AI replies pause.

Verdict
The clearest difference is in-app purchases: Sparkstep at none against Sidle's 3. Sparkstep also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.0). Sidle's advantage is ads (none vs shown). On price there is nothing between them.
