## Review summary

The Tandem t:slim Mobile App shows strong bolus convenience and data sharing when it connects, but is hampered by reliability issues. The most recurring problems are Bluetooth disconnects and unpairing, alarm/notification fatigue with limited control, Dexcom CGM data gaps, frequent login/re-pairing requirements, and time-sync misalignment between phone and pump. Positive notes mention convenient bolus from the phone and ease of data upload to healthcare teams, highlighting a solid concept that is undermined by frequent connectivity and notification problems.

### Pros

- Bolus delivery via the app is convenient and increases ease of use when the connection is working.
- Easy to upload data to healthcare providers.
- User-friendly and intuitive UI when connected.
- Overall ability to manage boluses from the phone adds convenience.

### Cons

- Frequent Bluetooth connection drops and unpairs with the t:slim pump, requiring re-pairing or app restart.
- Alarm fatigue: excessive, repetitive alerts and notifications with limited customization or silencing options.
- Dexcom CGM (G7) data integration issues: signals lost, data not updating, and inconsistent pump readings.
- Frequent login/logout and re-authentication problems: app often logs out and requires re-download or re-pairing.
- Time synchronization problems: phone and pump clocks drift and daylight savings/time zone changes cause misaligned alarms.
