Verdict
The clearest difference is rating: Timebirds at 5.0 against Polar Flow's 4.6. Timebirds also leads on monetization model (free vs free with in-app purchases). Polar Flow's advantage is ratings volume (50K vs 1). On price, review sentiment, update cadence and ads 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. Polar Flow sells 1 in-app purchase, starting at $8.99 per month and Timebirds sells 1 in-app purchase, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Timebirds holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Polar Flow has 50K ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 50% and 50% positive.
Polar Flow ships an update monthly, Timebirds every 3 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
