# Companion app for GLP-1 weight-loss injections (dose reminders, drug concentration curves, photo-based protein estimates, weight charts), taken out of the US. Local-language versions that recognize local drug names and generics, subscription or one-time purchase. Brazil is validated; Taiwan, Korea, and Latin American Spanish-speaking markets are still open.

Open Trackable · regional expansion (health subscription) First seen 2026-11-01 · last updated 2026-11-07

Status

Open (5 already charting in Brazil's two storefronts; Taiwan, Korea and Spanish-speaking Latin America still open)

Why now, and how long the window lasts

Brazil cut prices after generic tirzepatide launched in year 2026, and users spread from the rich to the middle class. Monju's blurb name-checks Mounjaro, Ozempic, Wegovy, and local brands Tirzec, LipoLass, and "TG (tirzepatida genérica)". Every country that cuts GLP-1 prices repeats this, and the window follows each country's generics and insurance rules. Taiwan and Korea are happening now.

Confidence

中高(巴西两端 5 家同时在榜,Monju 口碑 4.3–4.5 星);台湾、韩国的空位是推断。推翻条件:Monju 30 天内掉出巴西 H&F 畅销前 20;或 Shotsy、MeAgain 推出葡语、繁中、韩语版。

- Meta Ad Library (11-02): searching GLP-1, software advertisers are only two English small accounts: "GLP-1 Tracker" (App Store 6758916201) running 13 ads, Ourax Apps (com.glpone.glp1tracker.weightloss) 27 ads; the rest are pharmacies and supplements. Monju and OzemPro are not in the library (English keywords, so Portuguese campaigns are not visible).

## Already doing it

Brazil: Monju, OzemPro, GLP-1 Control, GLProgress, Mondiário; Taiwan: Molife, mojo; Korea: 삐약 (community-style, free); French: GLP1Suivi; US: Shotsy, MeAgain; English: GlowAgain (listed for sale).

## The hardest step

Content and compliance, not technology. You have to know local drug names, dosage ladders, and generic strengths without giving medical advice. The only recurring Monju complaint is "says free but charges for everything".

## Who it's for

Speakers of Portuguese / Spanish / Traditional Chinese / Korean / Japanese 1–2 people; build for both iOS and Android (Brazil's Android volume is no lower than iOS); subscription, or one-time purchase (GLP-1 Control at R$19.99 also charted). A meal-plan GLP-1 option is covered in [017], and the playbook is in [019].

## Should every product builder know this?

No. But anyone in health should know the chain: "drug price cut → user base expands → local-language companion app needed".

## Change log

2026-11-07

Codeway's Dosely is buying 120 → 93, and the same company's scanning app 79 → 31, both collecting within a week. A big player tested the waters and pulled back, so the local-language gap hasn't been taken yet.

2026-11-04

Big player entering: Codeway (a leading Turkish app factory, publisher DEEP FLOW SOFTWARE SERVICES) GLP-1 Tracker: Dosely (App Store 6787922283,8-13 launch, GP com.codeway.glpone) Page running 120 ads (passed the screen as "young apps buying ads"); App Store only 78 ratings, br Free category #131, not yet gaining traction. The same company this week is also scaling a new scanning app (22 → 79 ads). Codeway runs English and multilingual campaigns together, so watch whether it localizes into the local-language gaps (Taiwan, Korea, Latin America). Status unchanged; add to the disproof condition: Codeway's Dosely enters the Brazil H&F Top Grossing top 20.

2026-11-02
