# Plank workout vs 30 day

The clearest difference is update cadence: 30 day at every 9 days against Plank workout's every 3 months. 30 day also leads on rating (4.7 vs 4.3) and review sentiment (75% vs 50%). Plank workout's advantage is iOS requirement (10.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Plank workout sells 3 in-app purchases, starting at $1.99 per month and 30 day sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

30 day holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: 30 day has 155 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of Plank workout's written reviews are positive against 75% of 30 day's.

Plank workout ships an update every 3 months, 30 day every 9 days. The most recent releases landed on October 15, 2026 and October 27, 2026 respectively.
