Foleil, an iPhone and Apple Watch health app, is a better Clue alternative when you want cycle tracking to sit beside the rest of your daily routine. A phase calendar, period-range estimates, symptoms and notes share an app with workouts, meal preparation, sleep and Ask Sprout, giving you practical places to organise the day around your own observations.
The useful question is broader than when a period might start. You may also want to record how you feel, organise a week of training and decide what to cook when the evening is full. Foleil brings those activities together, while keeping recorded experiences separate from predictions and interpretations.
Clue’s strength is dedicated cycle tracking with predictions, customisable experience tracking and cycle analysis, described in its product overview and Period Tracking explainer.
Competitor features below are described as of 19 October 2026.

How does the calendar keep observations and estimates distinct?
Foleil’s cycle calendar uses phase bands to make the month easier to scan, with recorded period days and a marker for today. The headline pairs cycle day and phase with a range for when the next period is expected. You can review the timing without having to turn it into a single certain date.
The distinction matters when looking ahead. A logged period is something you recorded; a future phase or period range is an estimate. Your own symptoms and circumstances still matter when you decide what to do on a particular day. Foleil’s cycle estimates are not contraception and do not establish fertility, hormone levels or a diagnosis.
Past-cycle strips give you a visual way to revisit recorded days and dates. The purpose is to make your history approachable, alongside the rest of the app, rather than to give a calendar authority over how you should feel.
How can symptoms and notes tell the fuller story?
A day’s entry can include symptoms and notes, with date controls to move between days. You can record the experience on the day it belongs to, rather than relying on what you happen to remember at the end of the week. These remain your reports, not clinical measurements.
That leaves room for an ordinary, mixed day. Perhaps you want to note discomfort, but also that you enjoyed a walk or had a busy evening. General mood, energy and soreness check-ins and the personal journal provide other ways to describe your experience. The cycle record can sit within that wider account without explaining every part of it.
When you revisit the week, separate what was recorded from what you infer. An experience happening near a particular cycle day does not prove why it happened. A thoughtful note can be useful without requiring an automated explanation.
Can you update the tracker while talking to Sprout?
Foleil lets definite first-person period statements in Ask become a visible tracker card. If you describe when your period started or record spotting on a particular day, the card shows the proposed day-by-day entries. You can check that the dates and descriptions match what you meant.
With Update from Ask enabled by default, eligible statements update the tracker and show an Updated card with Undo. Turn automatic updating off if you prefer the card to wait for you to tap Update tracker. Undo removes the additions made by that update, giving you a way to correct an unwanted addition.
The writing step follows rules for definite statements rather than asking a model to decide whether a health record should change. A question, a hypothetical or someone else’s experience should not become your period entry. This makes the conversation useful for recording an experience while keeping the visible card central to checking the result.
How can training stay practical alongside cycle context?
Foleil gives your training its own tools: programmes, training days and a reviewed week shaped around your activities, equipment and availability. You inspect and apply a proposed week. At a session, available exercise guidance sits beside sets, optional weights, the rest timer and the next set in the runner.
Cycle notes can be part of the context you consider while organising that week. They do not prescribe a phase-specific training rule. The practical advantage is having your plan, recorded sessions and personal observations close enough to consider together, while keeping the decision yours.
For a Wednesday with limited time, you might first check the planned session and then sort dinner. Foleil gives each task a place. A cycle estimate does not need to determine either choice for the joined routine to be useful.
Why keep meal preparation close to the same day?
Eat connects recipes, adjustable servings, ingredients and cooking methods with meal slots across the week. Choose a dinner, plan an additional serving for another day and review what ingredients are required. Those are concrete planning steps you can carry through the app.
Shopping requirements take confirmed pantry allocations into account, while your cupboard records still need updating. The resulting quantities describe recipe needs; they do not guarantee retailer stock or package sizes. That keeps the workflow about the food you are organising.
When you log a meal, a photo, spoken description or barcode can provide a starting point alongside manual entry. Review proposed foods, portions and returned product information before saving. Recognition and nutrition amounts are estimates, and permissions, device support and AI choices affect the route you use. Foleil’s advantage is connecting that reviewed record with the recipe and meal you planned.
How do Health and AI choices affect cycle context?
Apple Health exchange for cycle information follows the system permissions you allow, and cycle tracking remains subject to its own settings. Turning tracking off stops the cycle workflow; permission to use Apple Health is a separate choice made through iOS. Neither setting is a promise that every possible record will be available.
Cycle context in Ask follows the relevant data choices and existing AI consent. Optional online assistance can process your question and allowed context outside the phone. On-device support varies by device and model availability, and asking without saved records does not make an online question local.
You can therefore consider two different choices: whether to keep a cycle record and what context an assistance route may use. Foleil’s appeal is a connected routine with those controls available, rather than an absolute claim that sensitive information can never leave the device.
How should you compare apps like Clue for your own routine?
For Clue vs Foleil, start with what happens around the record. If you want to organise meals, follow a session and reflect on sleep in the same app as your cycle notes, Foleil’s broader daily workflow is the reason to choose it. This is a preference about how to organise your routine, not a claim of clinically superior predictions.
The comparison hub helps connect that choice to other parts of the day. The Flo comparison explores conversational period logging in more detail, while the Bearable comparison looks at moving from check-ins to practical actions. Use those distinctions to decide which tasks you want together.
Frequently asked questions
Is Foleil a Clue alternative for cycle tracking and daily planning?
Yes. Foleil connects a phase calendar, period-range estimates, symptoms and notes with training, food, sleep and reflection. It suits someone who wants those activities within one daily routine, with cycle information treated as personal context rather than a rule for every decision.
Can Ask Sprout log a period statement automatically?
Yes. Eligible definite statements can update the tracker when automatic updating is enabled, with the entries shown on a card and Undo available. You can turn automatic updating off and use Update tracker after reviewing the card instead.
Clue vs Foleil: which is the best cycle and wellbeing app for iPhone and Apple Watch?
The best fit depends on the tasks you want together. Foleil is a strong choice for a connected cycle, training and meal routine on iPhone, with a companion on supported paired Watches. This does not mean every cycle screen is available on Watch or establish superior prediction accuracy.
Can I use Foleil’s cycle estimates as contraception?
No. Cycle timing is estimated and is not contraception. Symptoms and notes are self-reports, and neither a calendar estimate nor an AI interpretation establishes fertility, a diagnosis or a treatment recommendation.
