New to STRNTH? You can now get a reminder for your first session and your next one. Turn it on from the card on your home screen. We also fixed a few things: - If you leave set-up part way through, you carry on from where you stopped. - Your weight is now optional in set-up. - Warm-ups are now off by default. You can turn them on in Settings. - The rest timer no longer covers the Skip button. - If a set has no numbers, the app now tells you why it will not tick. - Advice on a stalled lift now uses your own weight unit.
