Makes life so much easier and very easy to use

Irgendwie kann man die Dosen nicht mehr nur für eine Woche eingeben.

Bis vor paar Wochen konnte man in der App die täglichen Dosen für eine Woche bzw. für die Zeitspanne, die man individuell auswählen konnte auswählen. Aktuell gibt die App die Dosen für zwei drei Wochen vor was man als MarcumarPatient ja wöchentlich durch Messungen selbstständig dosieren muss. Somit ist die wöchentliche Dosierung auch weg wenn man‘s nach der letzten INR-Messung eingegeben hat. Bitte den Fehler zu beheben. Ansonsten ist die App super.

Response from developer

Hallo Yüki, Vielen Dank für Ihre Nachricht und Ihr berechtigtes Feedback. In der neuesten Version der App, Version 2.4.3, die gerade veröffentlicht wurde, sollte dieses Problem behoben sein. Die App speichert nun das vorherige Zeitintervall, wenn Sie mehrere Dosen auf einmal hinzufügen, und behält Ihr Dosierungsschema bei. Bitte wenden Sie sich an peter@web-factor.be, falls weiterhin Probleme auftreten sollten. Vielen Dank, dass Sie die App nutzen. Peter

Update

So I did hear back from the folks and was able to get it to schedule. I wish the schedule aspect was easier, even with the instructions it is still touchy. However, the reporting it gives is second to none and worth the effort.

Love this app

I love this app. It has made tracking my INR and medication doses so easy. It is easy to use and it’s easy to make changes. I can easily look back over my INRs to track how things are going. I also make notes about my doctor’s recommendations to skip a dose, or change my dosage, so I can track my history.

I recently had a problem where my past INRs weren’t showing up. The app people worked diligently with me over several days in order to try to fix the problem. Repeated emails back and forth between us, trying to work it out. As predicted by the app people, the most recent update fixed the problem for me. I cannot say enough about how much I appreciate the diligence of the people supporting the app.

Response from developer

Hi, sorry to hear you're experiencing problems! Yesterday a new version of the app was released (v2.4.1) which fixes some problems with corrupt INR values. This should solve your issue as it was reported by some other users as well. Thanks for reconsidering your review if the update works for you! You can contact me at peter@web-factor.be for further follow up, if necessary. Have a great day. Peter
