Payment and Purchase Rules 1 Purchase Method Premium Features must be purchased through the official Apple App Store payment channel (In-App Purchase - IAP). Prices are as displayed on the purchase page. 2 Purchase Content Purchase items are divided into two forms: consumable and permanent. Consumable items deplete gradually with use and can be repurchased; permanent items do not expire and are valid for life. 3 Subscription/Order Management Subscriptions are divided into two forms: Auto-Renewable Subscriptions and Non-Renewing Subscriptions. • Auto-Renewable Subscription: A service that automatically renews and charges fees at fixed intervals (e.g., monthly/yearly), unless the user actively cancels it; • Non-Renewing Subscription: Does not automatically renew or charge upon expiry; requires manual repurchase; • Users with auto-renewing subscriptions can view, manage, and turn off auto-renewal in their Apple ID settings on Apple devices; 4 Refund Processing Users may request refunds from Apple. Refunds are subject to the Apple App Store refund policy. The Service Provider does not directly handle payment disputes. 5 Service Interruption If verification fails due to force majeure (e.g., network failure, Apple server outage), Premium Features will be suspended until verification is restored. - Users can purchase Premium Features through the Apple App Store payment system.

Verdict
The clearest difference is update cadence: Pocket Day at daily against Bird Diary's every 3 weeks. Bird Diary's advantage is ratings volume (10 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bird Diary sells 3 in-app purchases, starting at $1.99 per month and Pocket Day sells 9 in-app purchases, starting at $0.29 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Bird Diary against 5.0 for Pocket Day. That said, the two scores are not equally well evidenced: Bird Diary has 10 ratings behind it against 1, so its average is the more settled of the two.
Bird Diary ships an update every 3 weeks, Pocket Day daily. The most recent releases landed on November 5, 2026 and November 9, 2026 respectively.
