ASO for health and fitness apps
Health and fitness is the most seasonal major category on both stores: search demand roughly doubles across late December and January, then decays until spring. Because store indexing and review take days and rankings take weeks to settle, the work that captures January has to be finished in November. Alongside the calendar, the category has its own constraint — health claims are policed by both the stores and, for anything medical, by regulators — so goal-led keywords and demonstrable outcomes beat medical-sounding promises.
Key takeaways
- Ship your January metadata and creative by late November; December is too late to rank in time.
- Goal-led queries ('lose weight walking', 'beginner strength plan') convert better than category terms.
- Avoid medical or diagnostic claims unless you are a regulated medical device — both stores enforce this.
- Plan the post-peak retention story too; January installs churn hardest of any month.
The seasonal calendar
| Month | Work | Why |
|---|---|---|
| September | Keyword refresh for resolution-intent terms | Competition sets prices and positions early |
| October | Creative production for the new-year angle | Design lead time, not store lead time |
| November | Ship metadata and creative | Ranking needs weeks to settle |
| December | Events, promotional content, paid ramp | Demand begins climbing pre-Christmas |
| January | Monitor and hold | Do not change a page mid-peak |
| February | Revert seasonal assets, focus on retention | The cohort that stays defines the year |
Claims, and where the line is
- Describe behavior and features ('logs workouts', 'guided plans'), not clinical outcomes.
- Never state or imply diagnosis, treatment or cure unless you hold the relevant regulatory clearance.
- Quantified promises about weight or health results invite both store rejection and advertising-standards complaints.
- Testimonial screenshots need the same substantiation as any other advertising claim in your markets.
What converts in this category
Specificity converts: a named plan for a named goal outperforms a general wellness promise, because the searcher already has the goal in mind.
Show real people at a realistic starting point. Aspirational fitness photography sets an implicit standard that raises install intent and lowers trial retention.
Where you have an Apple Watch, Health or Google Fit integration, say so early — ecosystem fit is a genuine differentiator in this category and is easily verified by the user.
Worked example: a habit-tracking fitness app after January
A workout app took roughly a third of its annual installs in the first two weeks of January and then spent eleven months on a plateau. The listing was written for that January audience — resolution language, transformation photography, before-and-after framing — which is exactly right for two weeks and slightly wrong for the rest of the year.
The fix was to stop treating the seasonal listing as the default. The evergreen metadata was rebuilt around the maintenance jobs people search for in March and September: 'workout log', 'gym tracker', 'strength progress', 'home workouts'. The seasonal variant still ships, but as a scheduled swap with a revert date attached, rather than as copy that quietly stays live until someone notices in April.
Health apps also carry a constraint most categories do not. Both stores are strict about medical claims, and 'lose 10kg in 30 days' is a rejection risk as well as a trust problem. Outcome promises were replaced with capability statements — what the app records, shows and reminds you to do — which cleared review and, unexpectedly, converted better, because the audience arriving in March is looking for a tool rather than a transformation.
What the agent does in week one
- 1
Day 1 — separate the two demand curves
Identify which of your keywords spike seasonally and which hold all year, and score the listing against the evergreen set first.
- 2
Day 2 — screen for claim risk
Flag any outcome or medical language in metadata and screenshots that could trip store review, and draft capability-based replacements.
- 3
Day 3 — rewrite the evergreen listing
Title, subtitle and description built for the maintenance searcher, with the resolution language moved into the seasonal variant.
- 4
Day 4 — schedule the seasonal swap
Queue the January creative with its live date and its revert date set at the same time, so it cannot outstay the season.
- 5
Day 5 — set the review loop
Route rating prompts to a genuine success moment — a completed session or a streak milestone — rather than to app launch.
Frequently asked questions
When should health and fitness apps prepare for January?
Metadata and creative live by late November. Ranking takes weeks to settle, so shipping in late December captures very little of the peak.
Can we claim health outcomes in the listing?
Only behavioral and feature claims unless you are a regulated medical device. Diagnostic, treatment or guaranteed-result language will fail review.
Is the January peak worth chasing given the churn?
Yes, but plan the second half. The cohort is huge and churns hard, so onboarding and week-one retention decide whether the peak is profitable.
