Frequently Asked Questions
How do I create a custom interval timer?
Open the Workouts tab, choose any template (such as OTM or AMRAP), and customize the work duration, rest period, and number of rounds before pressing Start.
Is an internet connection required to use the app?
No. Timer Gym works 100% offline. All workout timers, logs, and personal records are stored securely on your local device storage.
How does Timer Gym estimate my 1-Rep Max (1RM)?
When you log a weight and rep count (e.g. 60 kg x 10 reps), Timer Gym uses the standardized Brzycki and Epley strength formulas to calculate your theoretical 1RM in real time.
How do I request support or suggest a new workout mode?
You can email our engineering and product team directly at hello@splitmonkey.com. We respond within 24–48 business hours.
