The Best GLP-1 Apps in Germany: All 10 Ranked, Independently Assessed

In Germany the question of who pays was settled by statute before any doctor got involved: weight-loss medicines are Lifestyle-Arzneimittel under Paragraph 34 SGB V, excluded from the statutory catalogue by law rather than by case-by-case decision. That makes this a Privatrezept market from day one. Ten apps scored against the same six-pillar rubric, read for readers paying their own way. No paid placements, no affiliate links.

The short version, for people paying privately

The direct answer before the detail: Zenday App is our top pick for Germany, leading our GLP-1 app ranking at 4.55/5 and - unlike half this list - shipping a German interface.

The medication is the engine; Zenday is the steering. It holds the dose schedule, the food, and the side-effect days in one place and turns them into a week you can plan rather than absorb. The runners-up are Shotsy (4.35/5), the best-translated app in the field, and Regimen (4.05/5), the most technical, though English-only.

How we assessed them

Every app is scored on the same six pillars we apply across our software rankings, and the order falls out of those scores alone. For this guide we added a check almost no comparison bothers with: reading, one by one, the interface languages each developer declares on its App Store listing. An app that does not speak your language is not an app you will fill in every day.

One structural warning about this category: the apps write most of the rankings. Search the term in German or English and the first page is dominated by comparisons hosted on the products’ own domains, each placing itself at number one. Our weights are published before our results for exactly that reason.

Zenday, and what you get for paying twice

Paying for both the medicine and the software is a fair thing to resent, so the standard should be high. Zenday clears it by interpreting the cycle instead of storing it: injection day is connected to appetite, energy, and what to eat, rather than filed as a date.

Side-effect management is the spine of the product, which matters because side effects, not results, are what end most courses of treatment.

Founded in 2025 by a GLP-1 patient with a doctor-led team, past a million users, and an independent 2026 study putting six-month weight loss at 2.4x medication alone. Honestly: it is subscription-only with no free trial, positioned as a premium product, and its planner rewards people who like detail.

The language test: which apps speak German

It is the most useful filter for a reader in Germany and practically nobody publishes it. Per the languages each developer declares on the App Store, only half the list ships in German:

German interface: Zenday, Shotsy (17 languages), MyFitnessPal (19), Pep (10), and Phaze (8).

English only: Regimen, MeAgain, GlucoPal, Glapp, and DoneDose. These are good apps - MeAgain has the most complete daily logging in the category and Regimen the best pharmacokinetic modelling - but recording nausea, appetite, and mood in a language that is not your own is exactly the friction that gets a log abandoned in week three.

The runners-up

2. Shotsy - 4.35/5. The most polished app in the category and the best translated: 17 languages, German among them. One-tap dose logging, automatic injection-site rotation, side-effect severity tied to the dose timeline, estimated medication-level curves drawn from published pharmacokinetic data, and - above all - a PDF export built for the doctor visit. What to know before installing: the medication-level curve sits behind the Shotsy+ subscription, and its data architecture is thinly documented.

3. Regimen - 4.05/5. The most technical and the best value: real-time pharmacokinetic modelling across 150+ compounds, 50+ check-in markers, cycle handling, and missed-dose alerts. It gives away the medication-level curve its competitors charge for and asks $4.99 a month only when you add a second compound. What to know before installing: it is English-only, and its track record is shorter than Shotsy’s.

4 and 5 (tied at 4.00). MeAgain and Phaze tie from opposite directions. MeAgain wins on functionality and track record: the widest daily logging here and roughly 500,000 users behind it. Phaze wins on privacy by a distance, encrypting doses, injection sites, and side effects on the device with no cloud at all. Nothing in the rubric breaks the tie, so MeAgain places fourth on the broader product and Phaze fifth as the privacy specialist - with one caveat for a German-speaking reader: Phaze ships in German and MeAgain does not, which in practice reverses the order.

What changes in Germany: prescription, reimbursement, and price

Prescription required. Ozempic, Wegovy, and Mounjaro are prescription-only medicines. No app on this page prescribes, supplies, or substitutes for a clinician: all of them assume you already have a treatment plan.

The Lifestyle-Arzneimittel exclusion. This is the rule that shapes GLP-1 treatment in Germany more than any other. Under Paragraph 34 SGB V, medicines for weight reduction are classed as Lifestyle-Arzneimittel and excluded from the statutory benefits catalogue - so the gesetzliche Krankenkasse does not pay for Wegovy or Mounjaro when the indication is obesity. Prescribed within a type 2 diabetes therapy, cover is possible, and private insurers reimburse in some cases.

What that leaves you paying. Privately funded, Wegovy runs from about 172.73 € for doses up to 1 mg to 277.60 € per pen at the 2.4 mg maintenance dose, and Mounjaro from roughly 206 € to 489 € a month depending on dose. Over a year that is a four-figure sum paid entirely out of pocket.

That figure is the real argument for installing any of these apps. Even a premium subscription that helps you avoid skipped injections, eat enough protein, and get through the nausea week without quitting is a rounding error next to what you are already paying for the medication itself.

The Privatrezept economy

Paying privately changes the small logistics as much as the big number. A Privatrezept is filled at a pharmacy of your choosing at a price that is not fixed by the statutory system, refills are your responsibility to time, and there is no Kassenrezept paper trail tying the treatment together. Whatever record exists is the one you keep. That is an argument for an app that holds the dose ladder and the receipts in one place from the first injection rather than the third month.

Datenschutz: GDPR, the BfDI, and health data

GLP-1 use is exactly the kind of data German readers are least willing to leave lying around - and this is the market where that instinct is strongest and best supported. GDPR gives you access, portability, and erasure rights; the BfDI and the Länder authorities are more willing than most to act on them. Worth using before committing a year of treatment to any one app.

Phaze is the strictest: AES-256 on the device, no cloud storage, no analytics on medical data. GlucoPal asks for no account and backs up to your own iCloud rather than a vendor server. Zenday approaches the problem from another angle: its web version leaves no App Store trail and no icon on your phone screen. At the far end, MyFitnessPal carries a decade of advertising integrations and is the widest data surface on this list. None publishes an independent audit backing what it claims.

Tracker, nicht Telemedizin

Keep the two apart. Everything on this page assumes you already hold a prescription; telehealth platforms prescribe, supply, and invoice, which is a different business under different rules. Any app edging toward a prescribing posture is capped at 1/5 on our Safety pillar, however good its tracking.

How we score

We use an anchored 1-5 rubric: Functionality (30%), Privacy (25%), Reliability (20%), UX (15%), Honest pricing (5%), and Safety content (5%) - applied identically to every app and fully auditable. We publish the weights before the results so you can redo the arithmetic yourself; the detail is on the methodology page. No paid placements, no developer promo codes, and no hidden arrangements: funded from our own budget, not by anyone on this list.
