### 4/5 — 请增加药片的剂量

*2026-07-22*

产地为芬兰的华法林，1片为3mg，产地为中国上海的华法林，1片为2.5mg，请加入一片是什3mg或2.5mg的选项，中国地区销售的华法林只有这两个剂量，很多患者都需要切药器进行切药，您在app中设置的1片并不是3mg或者2.5mg

**Developer response:** 尊敬的用户：

非常感谢您的反馈，也感谢您进一步说明具体情况。

现在我更加理解您所遇到的问题：在中国市场销售的华法林，其规格可能与目前应用所支持的药物规格有所不同，例如每片 2.5 mg 或 3 mg。这款应用最初是根据主要使用市场中常见的抗凝药物规格进行开发的。

不过，您的反馈非常有价值。我会认真考虑在未来的更新中增加对这些其他规格的支持。

与此同时，由于应用的工作逻辑是基于每片药物所含的有效成分剂量，而不是单纯根据药品名称进行计算，因此您可以考虑一种可能的替代方案。

例如，如果您所使用药物的每片有效成分含量与应用中已有的某一种药物完全一致（例如每片 3 mg 的情况可以参考 Marcumar），您可以尝试在应用中选择对应的药物来创建治疗方案。为了避免混淆，您还可以自定义治疗方案的名称，明确标注您实际使用的药物名称，以便于识别。

当然，这只是一种技术层面的临时解决方案（workaround）。在使用之前，请务必仔细确认您实际使用药物的每片有效成分含量，与应用中所选择药物的规格完全一致。

再次感谢您提出这个非常有价值的建议。像您这样的反馈，对于持续改进应用，并让它更好地满足不同国家用户的需求，非常重要。

敬礼

### 1/5 — Man kann es nutzen

*2026-03-27*

Leider fehlen Medikamente in der App wie falithrom was man vor den Kauf nicht sehen konnte

**Developer response:** Sehr geehrte/r Nutzer/in,

vielen Dank für Ihr Feedback.

Ich möchte jedoch klarstellen, dass die in der App unterstützten Medikamente eindeutig in der Beschreibung im App Store angegeben sind. Darüber hinaus wird auch in den Versionshinweisen erläutert, dass die Unterstützung im Laufe der Zeit erweitert wurde (anfangs nur Coumadin und später auch andere Medikamente), auch dank der Hinweise von Nutzern.

Die App ist so konzipiert, dass sie die Dosierungen auf Grundlage des Wirkstoffgehalts pro Tablette der unterstützten Medikamente (z. B. Coumadin oder Marcumar) korrekt verwaltet. Aus diesem Grund kann sie auch mit anderen Medikamenten verwendet werden, sofern diese die gleiche Wirkstoffmenge pro Tablette aufweisen.

Es tut mir leid, wenn dieser Aspekt nicht vollständig klar war, jedoch waren diese Informationen vor dem Kauf verfügbar. Innerhalb der vorgesehenen Frist besteht selbstverständlich die Möglichkeit, eine Rückerstattung direkt über Apple zu beantragen.

Ich bin jedoch der Ansicht, dass eine so niedrige Bewertung nicht die tatsächliche Funktionsweise der App widerspiegelt, die korrekt entwickelt wurde und täglich von vielen Patienten genutzt wird.

Nichtsdestotrotz werde ich Ihren Hinweis berücksichtigen und prüfen, ob die Unterstützung weiterer Medikamente – wie dem von Ihnen genannten – in zukünftigen Updates ergänzt werden kann.

Falls Sie möchten, lade ich Sie ein, Ihre Bewertung im Lichte dieser Erläuterungen noch einmal zu überdenken.

### 3/5 — 首页不适配13mini屏幕

*2026-03-13*

开发者，请调整首页的比例，目前在13mini的屏幕上存在冲突显示，底栏和添加INR冲突，无法使用。

**Developer response:** 尊敬的用户，

感谢您的反馈以及您对问题的说明。

Apple 设备型号很多，屏幕尺寸和显示比例也各不相同。尽管我已经尽力针对不同设备进行界面优化，但在一些**屏幕较小的设备（例如 iPhone 13 mini）**上，由于可用空间较少，某些界面元素有时可能会显得比较紧凑或部分被遮挡。

不过，应用的所有功能仍然可以正常使用。

例如，如果您需要添加新的 INR 测量值，可以点击底部标签栏中的对应页面，然后在该页面中点击 “+” 按钮 来添加数据。

同样地，您也可以直接点击显示当天剂量的小组件来标记当天的药物已经服用。

主页上的三个按钮主要是为了提供快速操作的快捷方式，即使在某些设备上不太明显，应用仍然可以通过其他方式正常使用。

非常感谢您的反馈，我也会在今后的更新中继续改进界面的适配，以在不同设备上获得更好的显示效果。

如果以上说明帮助您解决了问题，并且您觉得应用对您有帮助，我将非常感激您考虑更新或提高您的评分。用户的评价对应用的持续改进非常重要。

再次感谢您的支持与理解。

Gentile utente,

la ringrazio per il suo feedback e per aver segnalato il problema.

I dispositivi della gamma Apple sono numerosi e presentano dimensioni e caratteristiche di schermo differenti. Nonostante gli sforzi per ottimizzare l’interfaccia su tutti i modelli, può capitare che sui dispositivi più piccoli – come iPhone 13 mini – dove lo spazio disponibile è più ridotto, alcuni elementi possano risultare più compressi o meno visibili.

In ogni caso, è comunque possibile utilizzare tutte le funzioni dell’app senza problemi.
Per inserire un nuovo valore INR, può semplicemente aprire la sezione dedicata tramite il pulsante nella barra inferiore e poi premere il tasto “+” presente in quella schermata.

Allo stesso modo, è possibile contrassegnare la dose come assunta anche toccando direttamente il widget che mostra la dose del giorno.

I tre pulsanti presenti nella schermata principale sono stati pensati come collegamenti rapidi, ma l’app rimane pienamente utilizzabile anche qualora questi risultino meno visibili su alcuni dispositivi.

La ringrazio molto per la segnalazione: terrò comunque conto del suo commento per migliorare ulteriormente l’adattamento dell’interfaccia nei prossimi aggiornamenti.

Se le indicazioni sopra riportate le permettono di utilizzare correttamente l’app e se la trova utile, le sarei molto grato se volesse aggiornare o migliorare la sua valutazione, poiché il feedback degli utenti è molto importante per supportare lo sviluppo e il miglioramento continuo dell’app.

Grazie ancora per il suo contributo.

Cordiali saluti,
Lo sviluppatore (e paziente TAO) di INR Coagulation Manager

### 4/5 — 请增加inr值的范围

*2026-02-12*

请将inr的值精确到百分位 如：inr的值为2.23，在app中无法输入，希望可以进行改进 ，谢谢🙏

**Developer response:** 尊敬的用户，

感谢您的反馈，也非常感谢您提出的建议 🙏

其实，在应用中已经可以输入精确到小数点后两位的 INR 数值（例如 2.23）。除了使用滑块（slider）之外，您还可以直接点击圆形控件中默认显示的数值。点击之后，会弹出数字键盘，您可以手动输入想要保存的 INR 数值，包括两位小数。

滑块和步进器（stepper）的设计目的是为了让数值输入更加快速、直观，同时提升界面的使用体验。但“手动输入”功能一直是支持的。

如果这一点在界面中不够明显，给您带来了困扰，我在此向您表示歉意。我会认真考虑如何在后续更新中让这个功能更加清晰易懂。

如果以上说明解决了您的问题，并且您对应用感到满意，若您愿意修改或提升您的评分，我将不胜感激。这对应用的持续改进和发展非常重要。

再次感谢您的支持与反馈！

### 2/5 — Did not work on my iPad or iPhone

*2025-10-17*

I purchased this app on Sep 5 and have been working with the developer but have not worked out the problem. I use an iPhone 13 Pro and iPad iPad Pro, gen 2 with both on OS26.  At first he thought it was the new operating system and then my settings.  We tried several things and it helped a little but on the entry page it didn’t. I emailed him last night morning and he responded quickly, but wanted me reset as my settings. I was not willing to do that. Anyway, I waited too long to get a refund. It didn’t cost much anyway. I’ll go back to using the app I’ve using for years.

**Developer response:** Dear user,

thank you for taking the time to share your experience. I’m truly sorry that you were unable to use the app as intended, despite my efforts to assist you personally through multiple exchanges via email.

As mentioned in our previous correspondence, the app itself functions correctly and has been thoroughly tested on current iOS versions. The issue you encountered was due to specific display and accessibility settings on your devices, which caused certain interface elements to appear hidden. Adjusting those settings — even temporarily — would have resolved the problem and allowed the app to display normally.

I completely respect your decision not to change your configuration, but I want to reassure other users that INR Coagulation Manager works reliably under standard settings and is used successfully every day by many patients (myself included — I am also on long-term anticoagulation therapy).

I remain grateful for your patience and the courteous communication we shared. Your feedback has nevertheless been useful to help me better understand how different device configurations can affect the display.

Kind regards,
Enrico Ferro
Developer (and TAO patient) of INR Coagulation Manager

### 3/5 — Utile ma migliorabile

*2025-10-04, version 2.1.2*

App utile e piacevole anche se necessita di alcune migliorie.
Inserendo il prossimo controllo INR ad una data specifica, salvando e chiudendo la app, alla riapertura la data del prossimo controllo è impostata a 9 giorni da oggi, anche se la modifico ritorna sempre a 9 giorni. 
- Non è possibile inserire il dosaggio come pillole ma solo come mg, il che obbliga a fare i conti, sarebbe più comodo inserire il numero di pillole direttamente, almeno per il warfarin.
- Il grafico INR è praticamente illeggibile, mostra solo un valore nonostante ne abbia inseriti uno per ogni settimana, sarebbe utile avere un grafico con linea dosaggio e linea INR.

### 1/5 — 好垃圾别买

*2025-09-08*

一点用都没有 剂量不会调 还夹杂一些英文 不实用白花钱

**Developer response:** 亲爱的用户，

很抱歉听到您对本应用的体验不佳。这里我想澄清一下正确的使用流程：首先需要创建一个或多个个性化的每周治疗方案。完成后，只需选择当周要使用的方案，相应的每日剂量就会自动填入对应的字段，然后点击“保存”，这些数据就会立即显示在主页面以及应用的其他相关部分。

我理解这个过程在第一次使用时可能不够直观，但在完成初始设置后，应用的使用会非常快捷和方便。

另外，如果您在某些界面中发现仍有英文文字，请您告知具体位置，我会在下一个更新中将其修正。

感谢您尝试使用 INR Coagulation Manager。我真诚地希望在您更好地理解其使用逻辑后，能够体会到它在治疗管理中的实际帮助。

🇬🇧 Risposta in inglese

Dear User,

I am truly sorry to hear that your experience with the app has been disappointing. I would like to clarify the correct workflow: first, you need to create one or more personalized weekly therapeutic plans. Once this is done, simply select the plan for the current week and the corresponding daily dosages will automatically be filled into the appropriate fields. After pressing “Save,” they will immediately appear on the main screen as well as in the other sections of the app.

I understand this process may not feel intuitive the very first time, but once the initial setup is complete, the app becomes very quick and easy to use.

I also apologize if you found any leftover English words or labels in the interface. If you could kindly let me know where you saw them, I will make sure to remove them in the next update.

Thank you for trying INR Coagulation Manager. I truly hope that, once the workflow is clearer, you will appreciate its real usefulness in managing therapy.

Best regards,
The developer (and TAO patient) of INR Coagulation Manager

### 2/5 — Passt leider nicht

*2025-08-24*

Für mich zu unübersichtlich und umständlich, habe die App wieder gelöscht.

**Developer response:** Sehr geehrte/r Nutzer/in,

es tut mir leid zu hören, dass Sie die App als komplex und wenig praktisch empfunden haben. Ich verstehe sehr gut, wie wichtig einfache und sofort verständliche Hilfsmittel für die Betreuung einer Antikoagulationstherapie sind.

Ich möchte jedoch betonen, dass die App nicht wirklich komplex ist, sondern lediglich eine kleine Lernkurve erfordert: Sobald man die Funktionslogik verstanden hat, ist die Nutzung eine Sache von wenigen Sekunden. Nachdem man ein oder zwei persönliche Wochenschemata eingerichtet hat, genügen nämlich zwei Klicks, um den gesamten Therapieplan in die App zu übertragen und so die wichtigsten Funktionen nutzen zu können: automatische Anzeige der Tagesdosis, tägliche Erinnerungen und die Möglichkeit, die Einnahme mit einem einfachen Tap zu bestätigen.

Dieses Projekt liegt mir besonders am Herzen, da ich selbst TAO-Patient bin (nach dem Einsatz einer mechanischen Aortenklappe) und die App täglich zur Verwaltung meiner eigenen Therapie nutze. Gerade deshalb habe ich großen Wert darauf gelegt, sie so klar, zuverlässig und nützlich wie möglich zu gestalten.

Ihr Feedback ist mir sehr wichtig: Wenn Sie mir mitteilen könnten, in welchen Bereichen Sie die größten Schwierigkeiten hatten, würde ich dies gerne berücksichtigen, um die Benutzerfreundlichkeit weiter zu verbessern.

Vielen Dank, dass Sie INR Coagulation Manager ausprobiert haben. Ich hoffe sehr, dass Sie mit ein wenig Vertrautheit die Wirksamkeit und den konkreten Nutzen der App für das Therapiemanagement erkennen können.

Mit freundlichen Grüßen,
Der Entwickler (und TAO-Patient) von INR Coagulation Manager


Dear User,

I am sorry to hear that you found the app complex and not very practical. I fully understand how important simple and immediately clear tools are when managing anticoagulation therapy.

However, I would like to emphasize that the app is not truly complex – it only requires a small learning curve. Once you understand the logic behind its functions, using it takes just a few seconds. After setting up one or two personalized weekly dosage schedules, only two taps are needed to “transfer” the therapeutic plan into the app and take advantage of its key features: automatic display of the daily dosage, daily reminders, and the ability to track each dose as taken with a single tap.

This project is very close to me, as I am myself a TAO patient (following the implantation of a mechanical aortic valve) and I use the app daily to manage my own therapy. For this reason, I have worked hard to make it as clear, reliable, and useful as possible.

Your feedback is very important to me: if you could share which areas you found most challenging, I would be glad to take it into account to further improve user-friendliness.

Thank you for trying INR Coagulation Manager. I truly hope that, with a little familiarity, you may discover the app’s effectiveness and real usefulness in managing your therapy.

Best regards,
The developer (and TAO patient) of INR Coagulation Manager

### 1/5 — Applicazione piena di bachi

*2025-07-07, version 2.1.2*

*2025-07-05, version 2.1.2*

I downloaded this app (paid the $.99 for it and on the very first screen is says to click on “Next” THERE IS NO NEXT TO CLICK ON!!!! 😡
