Restbell is a training timer for iPhone and Apple Watch, published by TheKnack. It is provided as is, for personal use.
Timing is never locked. Every mode, unlimited runs, five saved routines of your own, the presets, the full Apple Watch app, all default cues and export are free, offline, with no account and no time limit.
Restbell Pro is an auto-renewing subscription, offered monthly or yearly, that lifts the five-routine limit and adds cue packs and Watch extras. A 7-day free trial is available to new subscribers.
Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription in Settings › Apple Account › Subscriptions. Any unused portion of a free trial is forfeited when a subscription is purchased.
Restbell measures time. It gives no training, medical or health advice, and nothing in it should be treated as such. Train within your own limits.
To the extent permitted by law, TheKnack is not liable for any loss arising from use of the app. Your routines are stored only on your device — export them if they matter to you.
