Three short phrases after salah, thirty-three times each. About one minute, and a promise of forgiveness.
Right after the salaam, most of us have a gap. Fill it with three short phrases.
The Prophet ﷺ said that whoever glorifies Allah 33 times, praises Allah 33 times and declares Allah's greatness 33 times after every prayer, then completes the hundred with "La ilaha illallah wahdahu la sharika lahu, lahul mulku wa lahul hamdu wa huwa 'ala kulli shay'in qadir", his sins are forgiven, even if they are like the foam of the sea. (Sahih Muslim)
SubhanAllah, Alhamdulillah, Allahu Akbar. About one minute. No app, no notes.

Pick the one prayer you rush the most and do this after it today. Use your fingers or a set of beads, and keep going until you reach 33 of each.
