Capnolog is a case log for anesthesiology and surgical residents that fills ACGME's Case Log form on your iPhone. • Log a case in a few taps, from a template or your last case. • See each ACGME category next to the minimum, with your pace to graduation. • File on ACGME from your iPhone: Capnolog fills the form, and you press Submit. • Plan tomorrow's cases with each attending's preferences on the plan. • Catch up from a pasted case list, a CSV or a PDF. • Export your whole log to CSV or PDF at any time. • Medical students in any specialty track interviews, letters and the draft order. • Your log records the kind of case, never whose. FILE ON ACGME FROM YOUR IPHONE ACGME's Case Log page opens inside Capnolog. Sign in on ACGME's own page, and Capnolog fills ACGME's form from your log. You check the form and press Submit yourself. On a computer, the Capnolog extension for Chrome fills the same form. Capnolog never presses Submit, never sees your ACGME password, and no Capnolog server ever touches acgme.org. Filing past the first 50 cases is part of Capnolog Premium. Capnolog is independent and not affiliated with or endorsed by the ACGME. PLAN TOMORROW'S CASES Build tomorrow's list the night before. Each plan shows your attending's preferences, and the plan fills in the case log after the case. Send a plan as a PDF or as text; the shared copy leaves out patient details by default. Case planning is free for 30 days from your first saved plan. ROTATION-AWARE LOGGING (PREMIUM, ANESTHESIA) Enter your rotation schedule, and Premium learns each rotation from your own cases. The case form puts your rotation's details first, and the rotation's usual technique, site, and attending fill in with one tap. YOUR NOTES, FROM APPLE NOTES Keep attending preferences, checklists, and photos in notes. Bring your notes over from Apple Notes and review each note before saving. NEUROSURGERY Residents at any ACGME program can join. Say the operation, type your own shorthand, or start from a template. Insights counts your cases by primary code and training year, and imported notes land in the neurosurgery note template. MEDICAL STUDENTS IN ANY SPECIALTY Track each interview with the date, time, track and thank-you note, keep a Letters list, and build your draft order. The ERAS summary works without a case log, and on Match Day Capnolog saves where you matched. CATCH UP FROM A LIST Paste a case list, or import a CSV or PDF you exported. Capnolog reads the columns, skips the cases you already have, and adds the rest. Nothing pasted leaves the phone. PRIVATE BY DESIGN The case log records the kind of case, never whose. Your cases stay on your iPhone, and a de-identified copy syncs to Capnolog by default; turning off Case sync in Settings deletes that copy. iCloud Backup uses your own iCloud, encrypted so only your devices can read it. Medical record and case-ID fields are masked to their last four characters before they are stored. CAPNOLOG PREMIUM (OPTIONAL) Logging, progress, export, the paste import, and the calendar schedule import are free. Premium adds case planning after the first 30 days, rotation-aware logging in anesthesia, unlimited templates and attending notes, ACGME Case Log filing past the first 50 cases on the phone and in Chrome, case lists, and remembered import formats. Premium is an auto-renewing subscription, yearly or monthly. Payment is charged to your Apple Account at confirmation and renews automatically unless cancelled at least 24 hours before the end of the current period.

Verdict

The call

The clearest difference is review sentiment: Capnolog at 100% against Elsevier eBooks+'s 43%. Capnolog also leads on update cadence (every 2 days vs every 2 months) and rating (5.0 vs 4.8). Elsevier eBooks+'s advantage is in-app purchases (none vs 2) and ratings volume (1.9K vs 3). On price, ads, monetization model and device support there is nothing between them.
