# Hatchpedia vs WhatFly

The clearest difference is in-app purchases: WhatFly at none against Hatchpedia's 2. WhatFly also leads on rating (5.0 vs 4.5) and review sentiment (100% vs 80%). Hatchpedia's advantage is update cadence (every 9 days vs every 2 months) and ratings volume (67 vs 3). On price, ads and device support there is nothing between them.

Both are free to download. Hatchpedia sells 2 in-app purchases, starting at $2.49 per month. WhatFly asks for nothing beyond the download.

WhatFly holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Hatchpedia has 67 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 80% of Hatchpedia's written reviews are positive against 100% of WhatFly's.

Hatchpedia ships an update every 9 days, WhatFly every 2 months. The most recent releases landed on September 12, 2026 and September 4, 2026 respectively.
