A personal portable device keeper, comprising:

• a substantially cylindrical housing having a spindle axially extending internally and an opening or a port, a spool being disposed in said housing and supported pivotally by said spindle, said spool having a central cavity, a spiral or coil spring being disposed in said cavity and secured at both ends to said spindle and said spool respectively, a length of cord being secured at one end to said spool, wound around said spool, and exposed at the other end to said opening or port, said spool being urged by said spring and being rotatable about said spindle, said spool unwinding when the exposed end of said cord is pulled and rewinding when said cord is relaxed, a ratchet means for preventing said cord from being rewound, said ratchet means being independent of said shell and operable through said cord by such a pulling-then-releasing manner that, when released, said spool stops rewinding if said exposed end is pulled by a length longer than a first predetermined length but said spool rewinds if said exposed end is pulled by a length shorter than a second predetermined length and longer than a third predetermined length, said first predetermined length being longer than said second predetermined length, a secure means for securing or mounting said housing to an external object, said opening or port being rotatable with respect to said secure means, whereby after tying or securing a cell phone with strap holder by said exposed end, a user can operate said keeper with one-hand while handling or holding said cell phone.
