Verdict
The clearest difference is review sentiment: Whisper Lithium at 100% against Rain Bird's 31%. Whisper Lithium also leads on update cadence (every 3 weeks vs every 2 months). Rain Bird's advantage is rating (4.7 vs 3.0) and ratings volume (70K vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Rain Bird holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Rain Bird has 70K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 31% of Rain Bird's written reviews are positive against 100% of Whisper Lithium's, so the app with the better star average is not the one people write more warmly about.
Rain Bird ships an update every 2 months, Whisper Lithium every 3 weeks. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
