Verdict
The clearest difference is monetization model: GymNext Flex Timer at free against F1T's free with in-app purchases. GymNext Flex Timer also leads on ratings volume (2.1K vs 1) and device support (4 vs 1). F1T's advantage is update cadence (every 6 days vs every 3 weeks) and rating (5.0 vs 4.8). On price, ads and in-app purchases there is nothing between them.

Both are free to download. GymNext Flex Timer sells 2 in-app purchases, starting at $8.99 per month and F1T sells 8 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
F1T holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: GymNext Flex Timer has 2.1K ratings behind it against 1, so its average is the more settled of the two.
GymNext Flex Timer ships an update every 3 weeks, F1T every 6 days. The most recent releases landed on September 25, 2026 and September 10, 2026 respectively.
