Title: A Pilot Study of Mobile Directly Observed Therapy (mDOT) for Immunosuppressant Adherence in Adult Liver Transplant Recipients
Brief Summary: The investigators are interested in whether or not the use of a mobile health (mHealth) application increases the rate of immunosuppressant medication adherence among adult liver transplant recipients. The investigators aim to test this by randomly assigning transplant recipients to the intervention (use of an mHealth app to manage and track their immunosuppression regimen) or control arm (standard of care) upon discharge from their initial transplant hospitalization, and tracking medication adherence over time. The study population will be approximately 50 adult liver transplant recipients at the Johns Hopkins Hospital.


Options:
A: Inclusion Criteria:

* Greater than or equal to 22 years of age
* Receive a liver transplant at Johns Hopkins Hospital

Exclusion Criteria:

* Non-English speaking liver transplant recipients
B: Inclusion Criteria

1. Signed informed consent and or/assent
2. Between the ages of 18 and 70 years, inclusive
3. Current or future kidney transplant recipients, no more than 14 days after transplant and prior to hospital discharge. Inclusion of future kidney transplant recipients cannot exceed 30-days pre-transplant.
4. Able to swallow tablets and capsules at the time of randomization
5. Subjects must be receiving a primary or secondary kidney allograft from a deceased donor or from a non- HLA identical living donor
6. Negative cross match test, and compatible (A, B, AB or O) blood type
7. Subjects must have no known contraindications to tacrolimus
8. Women of childbearing potential (WOCBP) must have a negative pregnancy test and be willing to use 2 methods of contraception during the study and for 6 weeks after stopping the study drug.

WOCBP includes any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal (defined as amenorrhea ≥ 12 consecutive months; or women on hormone replacement therapy with documented serum follicle stimulating hormone level \> 35 mIU/cc). Women who are using oral, implanted, or injectable contraceptive hormones (intrauterine device), mechanical products or barrier methods (diaphragm, condoms, spermicides), are practicing abstinence, or have a sterile partner (e.g., vasectomy), will be considered of child bearing potential.

In addition, WOCBP who are taking MMF must use methods of birth control as stipulated in the package insert, namely:

Either intrauterine device, or partner with vasectomy, or one hormone (oral contraceptive pill, transdermal patch, vaginal ring, or progesterone injection or implant) and one barrier method (diaphragm or cervical cap with spermicide, contraceptive sponge, or male or female condom), or two barrier methods as described above.

WOCBP must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin \[HCG\]) at the time of transplant.

Exclusion Criteria

1. Those who receive simultaneous combined organ transplants
2. Subjects with clinically significant active infections (for example, those requiring hospitalization, or as judged by the Investigator) or malignancies
3. Recipients who are concurrently receiving belatacept or anticipate to receive belatacept as part of their immunosuppressive regimen
4. Subjects currently enrolled in another investigational device or drug study
5. WOCBP who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for 6 weeks after stopping the study drug
6. Women who are breast-feeding or pregnant with a positive pregnancy test on enrollment or prior to study drug administration
7. Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness must not be enrolled into this study.
8. Any psychiatric or medical condition that, in the investigator's opinion, may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study.
C: Inclusion Criteria:

* 18 or older
* can speak and understand and read English
* receive their first kidney transplant at one of the participating sites during enrolment

Exclusion Criteria:

* do not meet inclusion criteria
* have previously participated in a study entitle "Improving health outcomes of kidney recipients: A randomized controlled trial of a pre-transplant education intervention"
D: Inclusion Criteria:

* Subjects age 11 - 24 years
* At least 3 months post kidney transplant

Exclusion Criteria:

* Significant neurocognitive disabilities limiting the subject's ability to understand and participate on their own
* Unable to communicate in English or French (Montreal site)
* Unable to communicate in English (all other sites)
