The app is not released yet, so there is nothing to support quite yet either.
Once it is published, the contact address travels with the listing: on Google Play every app shows a developer email under App support on its store page, and that is the address to write to. It is deliberately not printed here — an address on an open web page is an address harvested by every crawler that passes.
Every message is read. If you are reporting something wrong with a sentence or a recording, the most useful thing you can send is the Spanish text of the phrase itself — that is enough to find it exactly, out of three and a half thousand.
The app keeps everything on your device and has no way to report a problem by itself, so a description in your own words genuinely is the only signal that reaches us.
Common questions
Do I need a connection?
No — not even the first time. Every sentence and every recording is inside the app when you install it. The app has no network permission at all, so it cannot reach the internet whether or not you have a signal. See the privacy page.
Is there an account?
No, and there will not be one. Nothing about you is stored anywhere but on your own device.
Where has my progress gone?
Because everything is stored on the device and nothing is synced, uninstalling the app — or moving to a new phone — starts you over. There is no account to restore from. If this matters to you, say so; it is the clearest argument for adding an export.
Why does it show my retention as 90% and not 100%?
Because 90% is the target. A scheduler aiming for perfect recall would show you every card far too often and waste most of your time on things you already know. The interval is chosen to catch each phrase just before it slips, which means a small share of cards are always about to slip. Seeing roughly 90% means it is working.
The coverage number seems low.
It is honest rather than low. It reports how much of ordinary spoken Spanish is made of words from phrases you have actually consolidated, and the complete course tops out near 73%. No deck of sentences gets you to comfortable understanding on its own — that is what the listening hours in Progreso are for.
Dictado marked me wrong and I typed what I heard.
Accents are forgiven, so que is accepted for qué. But ñ is treated as a genuinely different letter, because it is one: año (year) and ano are not the same word. If you think a marking is wrong beyond that, send the phrase.
Sessions feel too long, or too short.
Change Frases nuevas al día. Each new phrase becomes two cards, so eight phrases is sixteen new cards a day. Lower it when reviews pile up; raise it when sessions end too quickly. Reviews already scheduled still come due either way.
I missed several days and now there is a pile of reviews.
That is expected and nothing is lost — the cards waited. Work through what you can; anything still due tomorrow will be there. Lowering the new-phrase setting for a few days lets the backlog clear without adding to it.
Is it on iPhone?
Not yet. An iPhone version is planned; the Android app comes first.
