A streak counts days. It does not count distance, and distance is the thing that decides an application: how far your current score sits from the cutoff of the programs you actually want. Before arguing about apps versus paper, it is worth looking at what the cutoffs are. We searched this site's program database, 1,042 records harvested through its public search index, and counted what the IELTS TOEFL Duolingo cutoff database search actually turns up for the test with the widest spread of minimums.
Searching the IELTS, TOEFL and Duolingo cutoff database

Of the 1,042 records, 363 state a Duolingo English Test minimum, and they cluster tightly. The median stated minimum is 115. Almost two thirds of them, 237 records, sit between 100 and 120, and 298 of the 363 ask for 105 or more. The floor is not 90, whatever the friendliest corner of the internet told you, and the ceiling is real too: 55 records ask for 130 or more. A daily streak aimed at "Duolingo, eventually" is aiming at nothing. A streak aimed at the 20 points between your last mock and 115 is a plan.
The same search discipline applies to the other tests. In the same harvest, 965 records state an IELTS minimum and 764 state a TOEFL one, so whichever test you are preparing for, the cutoff you need exists as a countable fact, not a vibe. Check your target programs in the database first. Then argue about stationery.
The same database, two more tests
Duolingo is the dramatic case because its minimums spread so widely, but the same point holds for the tests with tighter ranges. In the same harvest, the 965 records stating an IELTS minimum centre on 6.5, with half of them at that band exactly. The 764 records stating a TOEFL iBT minimum have a median of 82: 236 sit at 79 or below, 268 between 80 and 89, and 119 at 100 or more. Nobody's target should be "a good TOEFL score" in the abstract. It should be the 82-ish middle if your programs are typical, or the specific number your shortlist publishes if they are not.
This is also where the two tools in this comparison divide their labour honestly. The database tells you the distance. The streak, paper or digital, is just the engine that closes it. Choosing the engine first and the destination later is how students end up with a beautiful 40-day streak pointed at a score nobody asked them for.
Where streak tracking wins
- Reminders that fire. Paper never nags you, and the day you forget is the day the chain breaks.
- Frictionless logging. One tap versus finding the notebook, and small friction is what kills habits in week three.
- Visual pain. A broken 20-day streak hurts enough to study, and that mild dread is a feature, not a bug.
Where paper wins
Writing practice is the honest case for paper. Handwriting Task 2 essays beats typing them for the paper-based test, and a notebook cannot show you a notification. Paper also wins on distractions: your phone is also TikTok, and the streak app lives one swipe away from it. Neither tool wins on the thing that matters most, though. Neither one knows your cutoff unless you tell it.
The hybrid that actually works: phone app for daily tasks and streaks, paper notebook for writing practice. TestReady handles the streak side at $9.99 per mock; a two-dollar notebook handles the rest.
Paper has its own version of this discipline, for the notebook loyalists. Write the cutoff on the first page of the planner, not the first day you happened to start. Every weekly spread then gets judged against a number that came from a real admissions page, and a missed day reads as distance reopening rather than a broken decoration. The medium matters less than the anchor. An unanchored app streak and an unanchored paper chain fail in exactly the same way: quietly, and right up until the application deadline makes the gap visible.
Set the streak target from the gap
The 8-Week Score Sprint Planner starts from the gap itself: your test, your test date, your current score and the target the database says you need. It turns those four facts into a week-by-week plan with daily tasks, which is what a streak should have been measuring all along. Keep the streak, by all means. Just make it a streak of days spent closing a known distance, counted against a cutoff you looked up, not a number you hoped for.
