Both plans, monthly and annual, include a 14-day free trial if you haven't had one before. In the app, open the AI Coach tab (or open Settings and tap Unlock AI features), choose Monthly or Annual, tap the button to start your free trial, and confirm with your Apple ID. Prices are always shown live from the App Store for your region, so what you see is what you'll pay.

The subscription unlocks your AI Coach. Ask it about your training, your food and your day, and it answers from your own workout plan. It writes meal plans for each kind of day, logs food from a photo, a barcode, a nutrition label or a description, and writes a review of your week or month. It also unlocks the Supplements section and the Shopping list on the Nutrition tab, a strength chart for each lift on the Progress tab, reading a weight from a photo of your equipment, and running your workout hands-free from your Apple Watch. Your workout plan and its phases, timers, nutrition targets, the Tracker, Apple Health sync and your live heart rate on your Apple Watch come with the app.

Your subscription is handled by Apple, so it's cancelled through Apple rather than inside Strathlon. The quickest way: in the app, open Settings and tap Manage on your subscription card, which opens Apple's native subscription screen.

You can also cancel directly through Apple at any time:

• Open Settings on your iPhone.
• Tap your name at the top, then Subscriptions.
• Select Strathlon, then Cancel Subscription.

Your subscription auto-renews unless you cancel at least 24 hours before the period ends. When you cancel, you keep access until the current period runs out.

Tap Restore Purchases on the subscription screen, and make sure you're signed in with the same Apple ID you subscribed with. This also restores access on a new device or after reinstalling.

The AI Coach knows your profile, goals, sports and today's targets, so its answers are tailored to you. You can ask questions, request a full-day meal plan, log food from a description, or analyse a meal from a photo. To do this, the relevant text and any food photo are sent securely to our AI provider (Anthropic's Claude, via a Cloudflare proxy we operate) to generate the response. You can send the coach up to 50 messages a day, and the count resets each day. See our Privacy Policy for the full detail on what's sent.

Add a short description of the dish before tapping Analyse Photo (e.g. "Sri Lankan beef curry with coconut milk"). It dramatically improves accuracy for mixed or homemade meals. Remember, all photo and description results are estimates you can edit before adding them to your tracker.

Check you granted access: iPhone Settings → Privacy & Security → Health → Strathlon. Strathlon reads the figures you allow and, with your permission, saves the food you log in it (calories, protein, carbs and fat) to Apple Health; if you use Strathlon on an Apple Watch, the watch app saves the workouts it records to Apple Health. Strathlon uses what it reads to keep your targets and your Progress tab up to date.

Yes. In the Settings tab, Goal & plan → Change goal or experience takes you back through onboarding to change your goal or experience level; your tracking history is kept and a backup is made automatically first. Your sports, their order and their sessions are under Nutrition & Sport → Edit in Settings, and Edit schedule on the Plan tab sets your weekly gym and sport days.

Yes, as much as you'd like it to. Log your period in Apple Health, allow Strathlon to read it, and the app adds short notes for where you are in your cycle: tips for eating around your period on the Nutrition tab, a training note on the Plan tab, and a Cycle & energy tile on the Progress tab when water retention around your period may be nudging the scale. Your logged period days are also shaded on your weight chart.

Three optional switches take it further: Ease my targets in my pre-period week adds about 100 kcal to your calorie target in the days before and during your period; Cycle-aware training guidance adds a stronger train-by-effort suggestion on those days; and Share my cycle phase with the AI coach tells your coach a general phase word. They're all in Settings → Cycle-aware insights. What each switch does.

Yes, it's your choice. The cycle notes appear once you've logged a period in Apple Health and allowed Strathlon to read it, and the rest of the app works the same either way. Apple's own Health permission screen asks you once, and you can switch Cycle-aware insights on or off at any time in Settings → Cycle-aware insights.

Yes. Strathlon works out where you are in your cycle on your phone and keeps your period dates, flow, symptoms and history private, along with the cycle-aware training suggestions on your Plan. Your cycle details are kept separate from Strathlon's iCloud backup and from your written weekly reviews.

Your AI coach hears about your cycle through two switches in Settings → Cycle-aware insights, and both start switched off:

• Share my cycle phase with the AI coach shares a general phase word, such as “pre-menstrual”.
• Ease my targets in my pre-period week shares your adjusted calorie target and a note that it was deliberately adjusted. With the phase share on as well, the note also gives your cycle as the reason.

To clear the cycle estimates Strathlon keeps, use Settings → Reset & Data → Cycle data; your Apple Health logs stay exactly as they are. Section 4A of our Privacy Policy has the full detail.

Your training stays as programmed. The cycle notes suggest, and your sets, reps and weights stay exactly as they are.

You can also choose to change one number. With Ease my targets in my pre-period week on, your daily calorie target goes up by about 100 kcal in the days before and during your period, carried by about 25 g of extra carbs, so your protein and fat targets stay where they were. The Nutrition tab, the Tracker and your AI coach all use the same eased figure. When your target is set for a goal, the Tracker also shows a short “Eased” note, so the change is easy to see.

Yes, and it learns from your own dates. Strathlon looks at the periods you've logged over roughly the last six months, takes your typical gap between them, and expects your next period about that far after your last one. It keeps that estimate between 21 and 40 days, and uses 28 days until you've logged two periods.

The notes for your period appear on the days you've logged flow, so they always match your log. The pre-period notes are a forecast, so with a cycle that varies they can arrive a little early or late. The estimate runs for 40 days from the start of your most recent logged period and starts again when you log your next one, and you can switch Cycle-aware insights off any time you'd like a break. If your periods are often very irregular, very heavy or painful, or they stop, talk to your GP.

Strathlon's cycle notes follow the bleeding you log in Apple Health, whatever contraception you use. On many hormonal methods the monthly bleed is a withdrawal bleed rather than a true period, and the hormone ups and downs the notes describe are often smaller or replaced by steadier levels, so you may find the notes less relevant. You can switch them off whenever you prefer, in Settings → Cycle-aware insights. Our guide explains more: if you're on hormonal contraception.

Turn on I am pregnant in Settings → Health & safety. The switch is there on every profile, whatever sex is recorded, and a one-time note helps you decide what happens to your current programme.

While your pregnancy is recorded, your Plan tab shows the UK Chief Medical Officers' and NHS activity guidance for pregnancy, with the source named against every line, and effort is guided by how it feels, using the talk test. Your calories stay at what you burn, your weight goal is set aside for the pregnancy, and your meals, weight and activity keep logging as normal. Your AI coach is told about your pregnancy with every message, so its answers follow the same guidance and point you to your midwife or GP for anything specific to you.

Your midwife's or GP's guidance always comes first. Turning on I am breastfeeding works in a similar way, with the UK guidance for after childbirth. How it works.

Strathlon builds your workout plan, your targets and your coaching from your own profile and logs at every age, so they follow you through perimenopause and beyond. Its hormone therapy setting (Settings → Body & stats → Hormone therapy) includes HRT for menopause as its own answer, and HRT for menopause uses your standard calorie estimate.

The cycle notes follow the periods you log, so as your periods change, the notes change with them. Strength training is worth keeping up, too: it's linked to better bone density, studied especially after the menopause (why lifting matters). Talk to your GP about new or unusual bleeding, hot flushes or sleep changes.

Yes, with one switch. On a profile that records testosterone therapy, cycle features start switched off, because periods often stop or become irregular on masculinising therapy. If you still have periods, turn on I still menstruate in Settings → Cycle-aware insights and everything works as it does for everyone else.

For many people the body holds on to some extra water around a period, which can nudge the scale up for a few days. It's temporary water rather than fat, and it clears by itself. Strathlon shades your logged period days on your weight chart and, once you've weighed in on enough of them, its Cycle & energy tile shows how much higher your own scale tends to read on period days. Judge your progress across the whole cycle, rather than one morning. The science.
