Any "Flexi-Pomodoro" android App ?

There are a lot of android Pomodoro app out there, and I tried a few in the past with no success: Despite the pomodoro "discipline" probably being a key aspect of the method, the lack of "little flexibility & real time adaptation" has so far always been a deal-breaker for my use, despite I appreciate the overall principle. I would much appreciate some help to identify pomodoro-related apps that have some "flexibility" features that seem interesting to me : At break-time & if the user does not interact : automaticaly "skip" the break-times and start of a new work-session while aggregating the skipped break-time duration in a break-time "saving account" that the user can activate any-time (eg. interupts the next work-session at the end of a task, or add to the next planned break). Equivalent would be the possibility to easily add time to the current session (ex. +5min; +10min buttons) while also increasing the break-time "saving account". Possibility to snooze/repeat the end-of-break alarm (and the beginning of a new work-session) in a limited manner. The ideal would be having variable time snoozing delays : eg. for a 10min break, possibility to repeat alarm at +3min, then +1min with distinctive "final" alarm. - sometimes you are also doing stuff that can suffer interruption during breaks :-) ! An optionnal but nice addition could also be a possible "custom" (shorter) work/break session as a first session, to facilitate getting into the rythm. Any experience of Pomodoro-type Android apps having such features ? Thanks a lot for your help !
