Frequently Asked Questions
Is KILO free?

What does KILO Pro include?
KILO Pro unlocks AI workout summaries on Apple Intelligence-capable devices, Apple Watch companion features, unlimited templates, unlimited custom exercises, advanced analytics, exercise and timer controls from Live Activities, rest timer alarms, strength goals and progress tracking, and KILO Account sync.
How much does KILO Pro cost?
KILO Pro is available inside the app for £3.99 per month or £29.99 per year. The yearly plan is the best value and saves about 37% compared with paying monthly.
How do I manage or cancel KILO Pro?
KILO Pro subscriptions are handled by Apple through the App Store. After subscribing, you can manage or cancel from your App Store account subscriptions settings.
What devices does KILO support?
KILO runs on iPhone and Apple Watch. The iPhone app requires iOS 26 or later. The Apple Watch companion is included with KILO Pro. Live Activities run on supported iPhone models, with Dynamic Island controls shown on devices that support Dynamic Island. AI workout summaries require KILO Pro and an Apple Intelligence-capable device with Apple Intelligence enabled.
Do I need an account to use KILO?
No. KILO works fully offline with local storage. You can also sync your data privately via iCloud without creating a KILO account. KILO Account sync is available with KILO Pro.
How does sync work?
KILO offers two independent sync options. iCloud sync keeps a private backup in your own iCloud account and is available on the free tier. Optional KILO Account sync is included with KILO Pro and lets you back up your data securely on our servers. You can enable only one at a time from Settings.
Can I import data from another workout app?
Direct imports aren’t currently supported. If there’s a specific app you’d like to bring data from, let us know — we prioritise imports based on what users ask for most.
How are smart suggestions generated?
Suggestions are produced on-device from your own training history, your chosen experience level, and common best practices around recovery and progressive overload. No data leaves your device to power them.
How do AI workout summaries work?
With KILO Pro on supported Apple Intelligence-capable devices, KILO can generate a short recap on your device from the workout data already shown in your summary, including sets, duration, volume, muscles, notes, and personal records. If Apple Intelligence is unavailable, KILO explains that in-app and keeps the rest of the summary usable.
Does KILO read from Apple Health?
KILO uses HealthKit to read live heart rate data from your Apple Watch during active workouts and to write completed workouts back to Health. You control every permission from the system Health settings and can revoke access at any time.
Can I use KILO without Apple Watch?
Yes. The iPhone app can be used on its own. The Apple Watch companion adds live heart rate, workout starts, wrist-based set logging, and rest timers, and is included with KILO Pro.
How do I change units between kilograms and pounds?
Open Settings inside the app, then choose your preferred units. Existing workouts are displayed in the new unit automatically — the underlying data isn’t altered.
I found a bug or have a feature request.
Please email us with as much detail as you can — device model, iOS version, and steps to reproduce. Screenshots help a lot. Feature requests are welcome and genuinely shape the roadmap.
How do I delete my account or data?
You can delete your KILO account from Settings. Deleting your account removes your authentication account and synced KILO cloud data from our servers. Data that lives only on your device can be removed by deleting the app or clearing it from Settings. See the Privacy Policy for details.
