Opensolr emails you at 90%.
Your phone can tell you at 70%.
By the time a warning lands in your inbox, an index is nearly out of disk or out of monthly traffic. This app puts every index you own in your pocket, draws the two years of bandwidth behind it, and warns you at the percentage you pick — not the one the platform picked.
Version 5.0, 7.1 MB, Android 7.0 or newer. Free with any Opensolr account, including the free forever one. No ads, no trackers, no crash reporting.
01 — Why it exists
The control panel is on a laptop. The problem is not.
Disk fills and monthly traffic runs out while you are somewhere else. The website tells the whole story, but only once you are sitting in front of it, and the platform's own warning is sent at 90% — late enough that the next thing after it is a blocked index.
Warned when you choose
Pick 50, 65, 75, 80 or 90 per cent, for one index or for every index on the account including the ones you create later. The platform's 90% email still arrives; this is the one that arrives in time to do something.
Both numbers, at a glance
Every index with disk and bandwidth as a share of the plan, in the same four colour bands the website uses, so a list of forty indexes reads in one look.
Two years of trend
The monthly bandwidth chart per index, with total, average and peak. A quiet month and a month that doubled look different from across the room.
Nothing to break
It reads. Creating, deleting, reindexing and everything else that changes an index stays on the website, one tap away. There is no destructive button to hit by accident on a train.
It never sees your password
Signing in opens your own browser, so the account's two-factor authentication and lockout still apply. The key it receives is sealed by the phone's hardware keystore and excluded from backups.
Speaks your language
English, German, French, Spanish, Romanian, Japanese and Chinese. It follows the phone by default, or you pick one in Settings.
02 — The warning
90% is where the wall is. Not where the warning should be.
An index that hits its monthly bandwidth stops answering until the first of the next month or until the plan changes. Knowing at 90% leaves very little room. Knowing at 70% leaves a week.
The threshold is yours and lives on your account, so it follows you to a new phone. Setting it against every index covers the ones you have not created yet — the usual way an index ends up with no warning at all.
03 — What is on it
Four screens. Nothing you have to learn.
The app opens on your indexes and everything else is one tap away. It is the same data the control panel shows, arranged for a thumb instead of a mouse.
- Indexes — every index with disk, bandwidth, region, Solr version and document count. Tap one for the full picture.
- The index — both usage bars against the plan, the 24-month chart, the plan and its limits, the crawler and AI allowances, the server address, and a link into the web panel.
- Alerts — your own usage warnings and anything Opensolr announces, newest first.
- Account — the account-wide thresholds, which announcements may reach the phone, your plan's API limits, and the way back to billing.
- Settings — the language, and a check for a newer version.
04 — Signing in
Your browser does the signing in. The app just gets a key.
Tapping Sign in with Opensolr opens your phone's own browser on opensolr.com. You sign in there, with the password manager and the two-factor authentication you already use, and approve the app on a page that names the phone asking.
The app never sees the password. What comes back is an account key, sealed with a key generated inside the phone's hardware keystore, kept out of Android backups, and forgotten entirely when you sign out.
- No password in the app — the standard native-app flow, in a real browser rather than an embedded one.
- Nothing to configure — no API key to paste, no URL to type.
- Reads, and notifies — it asks for your figures and sets the thresholds you choose. It does not change an index.
- Keeps itself current — it checks opensolr.com for a newer version, and Android checks the signature before installing anything.
Put your indexes in your pocket.
