Changelog

What’s new in the app — the key changes across releases.

v0.126 – v0.135 July 2026 Latest

App & platform

  • LimnoLog speaks Spanish: we added a full Spanish language version — the interface, the indicator and methodology dictionary, help, Excel/CSV exports, PDF reports, and e-mail and push notifications. Terminology follows the Spanish scientific vocabulary of water monitoring (DQO, DBO₅, oxígeno disuelto). Switch the language in account settings, and set the export language per project.
  • Clearer project roles: if you only have view access (e.g. as an observer), the app now shows this upfront and stops offering actions you can’t perform anyway — no more confusing errors when trying to save. Sending feedback is easier to reach: from the menu in the project screen and directly from the “Reports” screen.

Reports, dashboards & integrations

  • We launched a public, live demo dashboard, “Reef & Coast Watch”: water level and temperature from six coral-reef monitoring stations (Hawaii, the Florida Keys, the Caribbean, Guam), updated automatically every hour. See for yourself what a public LimnoLog dashboard looks like with live data: https://app.limnolog.com/p/reef-coast-watch
  • Station maps now show all sites at once — even when they’re far apart (no more centring on the empty midpoint between them). The public dashboard link opens in the browser and can be copied with one tap, so it’s easier to check how the page looks and share it.

Other improvements

  • More reliable photo attachments in reports on older phones; the photo count on the session list now updates immediately after adding a photo; the project list no longer falsely shows “Offline” on large accounts; plus small interface fixes (the map no longer covers the project actions menu). Measurement and session counts — on the project list and in the admin panel — are accurate again. Push notifications now show a readable report status, and the Spanish language version received terminology and formatting fixes.

Reports, dashboards & integrations

  • Exports and reports now work reliably for very large projects (tens of thousands of measurements) — Excel, CSV and PDF files and the report generate all the way through, without breaking off. Restoring a project from a backup is resilient to repeated sensor readings, and reports show more clearly which indicators have no guideline set. Trend charts in the report now mark year boundaries, making multi-year series easier to read.

App & platform

  • Smarter language selection: after signing in the app shows the language set in your account — the same preference follows you on every device. Users outside Poland, the UK and Germany now see the interface in English instead of Polish.

Analysis & quality control

  • Faster chart loading for large projects: on subsequent visits the app fetches only new measurements instead of re-downloading the whole history. If you previously loaded the full dataset for analysis, a full refresh is one click away via “Refresh full data” — and the view now shows how many measurements you have on the device and when they were last refreshed.
  • Downloading the full history is now interruption-proof: if fetching a large dataset gets cut off (lost signal, app closed), it resumes from where it stopped next time — instead of starting over.
  • Fixed a misleading “Offline” message that could appear while a large project’s data was downloading despite a working connection — during a download you now see its progress, and the full-refresh button clearly shows that loading is already in progress.
  • Charts read better: month names on the time axis now match the app language, and on multi-year data the axis clearly marks the year — at the start and at every year change — so you instantly know which year the data is from. A single-day view shows the full date at the start of the axis (unambiguous in exports too), and with very dense sensor data we suggest switching to a daily or weekly view.
  • Opening charts and analysis for a large project now shows download progress and a “loading measurements — the chart will appear shortly” message instead of a blank screen. The progress no longer disappears when you switch project tabs, and the chart appears on its own as soon as the data is in.
v0.19 – v0.124 June 2026

Field work & data entry

  • Photo documentation: add photos to sessions and stations (camera or gallery, with GPS), tag them by type (station, sample, anomaly, equipment fault), view them on a map and export their location to GIS. The session list shows a counter, thumbnails and a highlight for data-quality events. It works offline too — photos taken with no signal upload once you are back online.
  • Field outings: a calendar of all your fieldwork. From an outing you can print sample QR labels and start measurement entry right away, and scanning a code opens the right session (the next bottles from the same outing land where they should). For fixed stations you can print permanent station QR codes. Scanning works offline too.
  • Reliable offline work: enter and correct measurements, create new sessions and export CSV/Excel files with no internet — data syncs automatically once you are back in range. After a longer offline break you stay signed in and see your projects instead of the login screen.
  • Set a station’s location straight from the map — point to it (click or drag the pin), search by address, or use your location, and the coordinates fill in automatically. The project map has “My location” and “Navigate to station”, so in the field you know at once where you are and how to get there.
  • In the mobile app (Android, from the store) you get a native camera QR scanner, device location, and file printing and downloads.

Analysis & quality control

  • Compare a sensor with the lab straight from raw telemetry: the app averages sensor readings in a window around each sample (mean, or a median that shrugs off spikes), so you can line up the methods without crunching it in a spreadsheet. For surrogate indicators (e.g. turbidity as a proxy for suspended solids) there is a new calibration mode with prediction error and a confidence band.
  • Quality control (QA/QC) for sensors: an equipment registry with a service log (cleanings, calibrations, replacements), control samples with standards and a control chart, automatic drift-risk flagging, retrospective drift compensation between services, and predictive maintenance. The raw value is always preserved.
  • Data quality center (the “Verification” tab): review anomalies grouped by type (out of reference range, frozen sensor, spikes) and exclude or restore a whole group in one click — with a confirmation and a count covering the entire project. In search you exclude the specific measurements you select. Excluded data drops out of statistics, charts and the report, but stays in the database and you can always restore it.
  • Data validation: automatic flagging and exclusion of faulty readings (out of range, “frozen” sensor, spikes) — charts, statistics and the report use only valid data. Method comparison sonde↔laboratory with Deming regression and a Bland-Altman plot tells you whether an online sensor can be trusted.
  • Expanded analysis: correlations with a trend line and fit (R²), methods robust to messy data (Spearman, Kendall), partial correlation, lag analysis and a map of all indicator pairs; Shewhart control charts highlighting outliers; a sample profile against guidelines; depth and CTD profiles (comparing vertical profiles of several sites).
  • We aligned indicator labels with international standards — codes based on Polish names (BZT5, ChZT, OWO, turbidity, total nitrogen and phosphorus, suspended solids, hardness, discharge…) are now widely recognised abbreviations (BOD5, COD, TOC, Turb, TN, TP, TSS, TH, Q…). Full names in your language stay the same, and files using the old labels still import.
  • More confident entry and clearer charts: a warning about unusual values during entry, bulk correction of many measurements at once (with full history), consistent number formatting (your language’s decimal separator), clearly distinct station colours on time-series charts, and a fixed daily value when a day mixes sensor readings with a manual entry.
  • On a computer you can now load the full history of even very large projects into analysis — charts, correlations and control charts cover the whole dataset, not just the most recent part.

Field work & data entry

  • When importing data from a sensor or data logger the app suggests automatic grouping into daily sessions — pick the last reading of the day or the arithmetic mean. The option appears when the file has more than 100 timestamps.

Reports, dashboards & integrations

  • A live PDF report builder: pick the date range, indicators, sections (summary, data quality, charts, statistics) and field photos, and the A4 preview updates instantly — download the finished report in one click. The report covers all of a project’s measurements (even beyond a thousand) and is fully available in German.
  • Public dashboards: share a project under your own read-only link without login, with tiles (current values, summary, station map, table, correlation chart, control chart, CTD profile), several charts side by side, a live preview, a station-status map, plus embedding and data access via API.
  • Much simpler connection of automatic data sources: pick a ready source (e.g. IMGW) as a single-click card and click fields straight in the response preview (CSV/XML/SOAP, many stations at once, source timezone). We added meteorological indicators, and sensor data is clearly separated from manual entries.
  • Reports sent automatically by email — pick the indicators and recipients, and a project summary reaches them weekly or monthly, with no login. We refreshed all emails and now send them in German too.
  • Exports with no size limit — CSV, Excel and PDF files include all measurements regardless of row count. We added a full, restorable project copy in one file (with stations, indicators, sessions, measurements and equipment) recreated in one click, plus better chart PNG exports (legend, clear axes, every point).

App & platform

  • We added a German language version (app and limnolog.com), refreshed the look (a consistent teal/petrol scheme in light and dark mode) and improved accessibility (keyboard navigation, screen readers, high contrast and larger text).
  • Contextual help — a “?” button on many screens opens a guide for exactly that place (from the bottom on phones, the right on desktop), works offline and comes in Polish, English and German, with search and a PDF handbook download.
  • On-device push notifications for guideline exceedances and report status changes (with a “push instead of email” option), plus reminders for scheduled sessions the day before sampling.
  • Faster, more stable start-up and sign-in — we pre-load mainly your active projects in the background, fixed Google sign-in on phones and working in several tabs at once, and field-collected data is better protected from loss.
  • Faster opening of large projects — after the first download the app fetches only new measurements instead of reloading the entire history.
  • Smoother project management: create from ready templates in three steps (lake, wastewater plant, river, urban monitoring), activate a draft in one click, delete sessions and whole projects (once archived, with confirmation and a backup), and edit session details after saving.

Reports, dashboards & integrations

  • Restoring a project from a backup now works reliably regardless of project size — importing a large archive no longer times out, and restore progress is shown on a bar. If any measurements need attention, you get a clear notice.

Other improvements

  • Other fixes: fixed a false offline mode (on some devices the app showed “offline” and skipped downloading data for fieldwork even with a working connection), local time instead of UTC in the PDF export table, better use of screen space on small phones, clearer session-list loading, a clear message while a large project’s report is being prepared, file printing and downloads in the Android app, content no longer hiding under the bottom bar, and many small interface and stability improvements.
v0.1 – v0.18 May 2026 (launch)

App & platform

  • First LimnoLog release — projects, sessions, stations, indicators and measurements in one place, an installable app (PWA) with a weekly email backup, team roles and inviting collaborators. Shortly after came a full English version, a desktop layout with a side navigation panel, and export of your own data (GDPR).

Field work & data entry

  • Offline work from the start — enter measurements without internet and data syncs once back online. You can also import from CSV, ODS and XLS files, and quick entry plus measurement search speed up working with lots of data.

Analysis & quality control

  • Analysis foundations: indicators calculated from formulas (including from other calculated ones), a dictionary expanded by dozens of indicators with version history, guidelines (min/max thresholds) as reference lines on charts, season comparison and a moving average, and soon after an advanced analysis mode (correlations with R², Shewhart charts, sample profile).

Reports, dashboards & integrations

  • Sharing and integrations from launch: export to Excel (multiple sheets), CSV and PDF, public project dashboards (read-only, with embedding and API access), automatic pull of measurements from devices and services (API connectors), and email notifications, exceedance alerts and daily change summaries.
