A 67-year-old sits and works out: a free chair workout app hit 85 710k installs by charging nothing

A small Philippine developer, BLUEBASE, listed "Chair Workout at Home" in August. By Nov 6 it had 717k cumulative installs and climbed to #5 on the US store's Health & Fitness Top Free chart. The content is thin, without even demo videos. It took off for three reasons: rivals charge subscriptions while it charges nothing, it is buying paid acquisition, and it had already walked this path once. Below: how it grew, where the money comes from, and whether you can copy it.

A review with 64 likes

In Oct 6, a US user gave it 5 stars on Google Play: "I only do the exercises in the chair because I'm 67 and my legs are bad, getting up is hard." The complaint follows: "The only thing I don't like is that you send a notification every 5 minutes." The review got 64 likes, one of the most-liked long reviews under this app.

That one sentence holds both sides of the app. One side is real need: seniors, people with disabilities, and people with bad knees and hips want a workout they can do seated. The other side is how it makes money: push notifications pull people back, and each visit means more ads.

What it is

A chair workout app. You pick a level and a goal, then follow low-impact seated moves. It has a weight-loss plan, daily reminders, water reminders, and a quiz. The store listing casts a wide net: "beginner, senior, busy worker, prefers low-impact exercise" are all listed as its users.

The store page says "Contains ads" and lists no in-app purchases (Google Play, 11-06). There is no iOS version.

The numbers: not a hit curve, but step-by-step scaling

Third-party install estimates (AppstoreSpy): a few hundred a day at the end of August, about 10k cumulative by Sep 10, about 19k by Sep 97, about 5k by Oct 365, and about 27k by Oct 625. From mid-September on it added a steady 1–18k a day, with a few days spiking to 4–60k (10-05, 10-08, 10-21).

No single video drove it. The curve rises in steps, which looks more like someone adding volume against a budget.

Who pushed it up: almost certainly paid acquisition

The rating count tells the story best. 717k installs produced only 985 ratings, about 0.14% of installs. Comparable apps sit above 1% (Google Play, 11-06):

That's a full ten times lower. It suggests many of the installers are low-intent users who tapped through, probably from interstitial and rewarded ads in other apps (inference). The 21 countries it charted in include Brazil, Nigeria, and Saudi Arabia, where paid installs are cheap, which fits. One one-star review is blunter: "It took over my home screen and installed at least 10 apps I didn't want... there's no chair workout at all." That kind of user comes from aggressive ad redirects. 1

Which ad networks it bought through, and how much it spent, can't be found from outside. Its ads don't show up in the Meta, TikTok, or Google ad transparency libraries. It may be buying through networks like AppLovin, Unity, or Mintegral, which don't publish their placements (inference).

Besides paid acquisition, a few visible helpers:

• The name is the search term. The title "Chair Workout at Home" is an exact search phrase, and the package name chairworkout.homeworkout.seniorsworkout.easy.loseweight packs in five keywords.
• Charting brings organic traffic. Reaching the top 5 in the US adds exposure on its own. And that spot isn't hard to hold: by its numbers, adding 1–15k a day is enough (inference).
• Cross-promotion. The "More by BLUEBASE" section on the store page links its three apps together.

It can't be found on TikTok, X, or in the press. No creators, no coverage.

It has walked this path before

BLUEBASE is based in the Philippines. The store page lists its entity as "BLUEBASE APPLICATION HOSTING SERVICES", with an address in Quezon City. Its website bluebaseph.com is a single landing page, and the privacy policy is hosted on Google Sites.

Its previous app, "Chair Workout: Women's Edition", had the same chair workout content, aimed only at women. According to androidrank's records, it passed 2025k installs in November 100, passed 2026k in May 500 and 1M in June, and is estimated at about 1.46M now. Its rating count is also only about 0.2% of installs, the same pattern as this app.

So this one probably came about like this: the women's version showed that "chair workout + free + ads" pencils out. So the same content got a broader, more precise name, was relisted in August, and the audience widened from women to everyone (inference). The developer also has "Weight Loss for Senior", with 10k+ installs, which looks like another test.

Where the money comes from

Ads only. The reviews show ads are heavy: "every tap opens an ad first," "a notification every 5 minutes," "I don't need an app to remind me to drink water." Water reminders and frequent pushes do the same job: pull people back so they see more interstitials.

The math probably runs like this: older users in the US and Canada carry high ad prices, while installs in Brazil and Nigeria are very cheap. Mixing the two and buying across both only needs ad revenue to cover acquisition cost, with no need for anyone to pay a subscription (inference). Its revenue and ROI aren't visible from outside and remain unverified.

Why users stay: it's free

Most of the top rivals charge subscriptions: LazyFit (7.88M installs on Google Play, with 940 ads running on Meta), BetterMe, Everdance, and EasyFIT with 7M installs. Open them and you hit a quiz and then a paywall. Search "chair workout app" on TikTok and the top results are ads for subscription products like Everdance and DanceFitme.

This app has no paywall. Reviews keep coming back to that:

"I finally found a free exercise app. I think I can stick with it this way, for myself and for my son." (10-08,15 likes)

"I'm severely disabled, and here I don't feel pressure. I only do what I can." (9-25)

"Simple and quick, my hip feels better after one session." (9-30,55 likes)

Almost all the negative reviews are about two things: too many ads, and annoying notifications (some say they still ring after notifications are turned off). Some also want demos: "If every move had a short video, it would be perfect."

Who it's competing with

Chair fitness and senior fitness is a proven niche with many players:

The only apps that are truly free, ad-only, and this big are BLUEBASE's own two. I haven't found any that copy it directly. Searching "chair workout" on iOS, the top results are all subscription products (App Store, 11-06).

How many people know about it

Almost nobody. There are no revenue disclosures and no press coverage, and no one is discussing it on X. Only data sites like AppBrain and Similarweb index it automatically. But everyone in this niche knows the demand exists, and subscription players have been spending on Meta and TikTok for years.

If it were you

Verdict: worth a test. The business runs on paid acquisition plus ad monetization. Anyone can build the product itself. Whether it makes money depends entirely on whether your acquisition and ad-monetization math works, and BLUEBASE hasn't published its numbers.

Who it fits: small teams that have run a utility app with "paid acquisition + ad mediation", who have AppLovin / Unity / Mintegral-type channels, who read LTV and eCPM, and who can work out what an install costs and how many days it takes to pay back.

Who it doesn't fit: people who only make products and count on organic traffic. This category is crowded on TikTok with content ads from the subscription giants, and ASO on the name alone can't carry 710k. Also people who want to build a subscription. That's LazyFit and BetterMe's home turf, and you can't outspend their ad budgets.

How to do it:

• Copy the playbook and fix what it did badly: add a few-second demo video for every move (reviewers ask for this by name), be more restrained with pushes (most of its 1-star reviews come from notifications), and leave room in ad frequency so you keep retention.
• Go to new markets: its content is English-only, and it ranks #72 in Germany and #74 in the UK, so it hasn't broken into those yet. Build localized versions in Spanish, Portuguese, German, and Japanese, with local exact search terms (for example, "ejercicios en silla" in Spanish, and 椅子 体操 in Japanese). Japan has many older users and high ad prices, so it's worth a try (inference).
• Validate with a narrow audience first (women, men, people with bad knees) at small scale. Only when it pays back, switch to a broad name and scale up. That's exactly what BLUEBASE did.

How to acquire users: buy installs through ad networks. Mix in cheap test geos first (US, Canada) and check whether 7 daily ad revenue covers the install cost. Put exact search terms in the title and package name. Once charted, organic installs take over.

When to launch: the earlier the better. January is peak season for weight loss and New Year resolutions, but ad prices drop after that and paid acquisition gets cheaper. Launch in December and scale in January (inference).

What would mean you read it wrong:

• This app's daily installs fell from over 10k after December to a few thousand, and it dropped out of the US top 20. That means paid acquisition stopped and the unit economics probably never worked;
• BLUEBASE added a subscription or in-app purchases. That means ads alone weren't enough;
• Subscription giants like LazyFit and BetterMe launched permanently free tiers. Your price advantage is gone;
• If your own small-budget test shows ad revenue under 30% of install cost after 7 days, don't spend more.
