Define the no-payment baseline before comparing brands
Write down what must keep working if you never start a trial or if you later cancel: camera setup, live view, motion alerts, event playback, downloads, identification, local recording, and household sharing. Verify each row separately. A free app may still have paid history or recognition, while a no-fee camera may still require an account, internet service, and the provider's servers.
Use current documentation as an example, not a shortcut
Birdfy currently documents an account-based Free tier with 30-day Moment retention, a 5 GB Collection limit, clips up to 20 seconds, and ten AI identifications per day, plus paid Plus and Pro tiers. Birdbuddy says its core system remains usable without paid membership and documents automatic captures, personal live view, downloads, and sharing in the free baseline, while some quality, AI, and guest-live features are paid. Perky-Pet says no subscription is required. These are current system-level examples, not proof for an old revision or Amazon variation.
Separate cancellation from storage and export
Before subscribing, learn what happens to new clips, previously saved clips, downloads, identification, shared access, and account data when a trial or plan ends. Birdfy’s current membership page says saved Collection items remain downloadable for one year after membership expiry but new items cannot be added; that current rule should take priority over older generalized cloud wording that suggests indefinite storage. Perky-Pet says ordinary media moves to Expiring after seven days and disappears three days later unless it is favorited or downloaded. Download footage you value before changing a service.
Compare the complete ownership cost without freezing a price
Record the current plan shown in the provider account, billing interval, trial end, taxes or app-store differences, supported memory card, and any required mount or power accessory. Prices and tiers can change, so this guide does not publish a static plan price. Choose only after the permanently included functions match your routine without relying on an expiring promotion.
