Clinical trial participants can streamline the clinical trial journey with the Suvoda app.
With a single app and only one login, participants can manage multiple trial activities including stipend payments, expense reimbursement, questionnaires, appointment scheduling, rideshare booking, and viewing travel itinerary details.
Work with your study coordinator or clinical research site to access your clinical trial on the Suvoda app.
The Suvoda app is designed exclusively for clinical trial participants. Site staff and sponsor study teams may use other tools provided by Suvoda to manage their clinical trial.

The worst part of the clinical trial is this app. The sync takes 10-15 minutes and you have to have the app up the whole time. Sometimes I can’t even get the regular stuff up without 5-7 minutes of waiting.

App takes FOR EVER to load study diaries. Study diaries are time sensitive so that is frustrating.. when I need to enter study information, I should be able to log into the app and know it will work.

App does not work well on Apple IPhone. Morning alarm does not always go off. Alarm sounds at different times. App cannot store or access FaceId password when opening. App needs an entertain bar showing amount of data being recorded, to avoid closing out or thinking that app is not working.
Developer Response
Thank you for sharing your experience. We understand how concerning it is when alarms don’t work reliably or when it’s unclear whether your data is being recorded. Your feedback helps us see where the app isn’t meeting users' needs, and we’re sorry for any inconvenience this has caused. Biometric authentication (Face ID) is available in the app if enabled by your clinical trial. The issue underlying your app performance experience has been addressed and will be updated in the new version of the app next week. We're committed to making sure the app works consistently for everyone. If you are a clinical trial participant, we ask that you please share this experience with your clinical trial research site so we can investigate the details of what you are experiencing.
